Master Post for Semi Lightweight Barrel Shootout

This post is a master archive for everything surrounding the Semi Lightweight Barrel Shootout.  The test was conducted over veterans day weekend of 2016.  The data was processed over several weeks following and as a result it became some what hard for the casual observer to jump into.  When reading this information remember that during much of the ammo presentation we did not know which barrel or ammo had shot the best and we simply presented it as we found it.

 

The original post can be found @ SLW Barrel Shoot Out.  We fluctuated back and forth with the procedure for the test and it went from something we could do for a good time to concentrating on presenting everything clearly.

 

Testing went relatively smooth but we found early that we would be presenting fewer groups than we would have liked and the process was taking longer than we had hoped.  All barrels shot one ten shot group of each of the ten ammo selections.  Then they fired two five shot groups of each of the ten ammo selections.  Resulting in 60 rounds fired of each ammo and 600 match grade rounds being fired overall.

We went after the ammunition break downs first and each of the ten can be found in the links below.

The data from each of the ammunition types was compiled in a Data Summery found @ SLW BARREL SHOOTOUT AMMO DATA SUMMARY

Finally we compared the barrels using both Extreme Spread and Mean Radius

We also have an ammunition comparison adding price in as a factor found in the Price for Performance rundown.

If you enjoyed reading about this particular test share with a friend.  We learned a lot on how we wanted to share data in the future and how much we could attack in a given time frame.

SLW Barrel Shootout – Australian Outback 69gr Ammo Performance

The ninth ammo we are posting the data for is Australian Outback 69gr HPBT Sierra MatchKing. Australian Outback isn’t as well known in the United States but this ammo is sure to turn some heads at around $0.55 a round (if you can find it in stock!). I was excited to see how it performed as it is a very budget friendly round.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


 

The Australian Outback 69gr shot an average of 2529.226667 fps between the 60 shots fired. Australian Outback 69gr had an Average Velocity about exactly in the center of the pack and had an Averaged Standard Deviation over 6 series of 10 shots of 28.99 FPS which was one of the highest SD’s recorded in testing. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.

Price vs Accuracy – Finding the best value in your ammo choices.

Now that we have established a baseline for all of the ammo tested, we can look at which ammo’s give us the best bang for the buck. While everyone would love to have a consistent sub-MOA performer (like Federal Gold Medal Match 77gr did in our testing) the $1.15-1.20 price per round scares a lot of people off, especially with some of the ammo’s we tested being available for under $.50 a round.

As we have done with all of our previous data, we wanted to present this as visually as possible, so here are graphs of each rounds averaged performance (in MOA) with all of the data (5 and 10 round groups averaged together) and seperately as both 10 and 5 round groups. The bottom of the graph features the price point of each round in US Dollars based off of actual retail price. All of the ammo’s we tested, except for ASYM 77gr, is sold by SG Ammo and I find them to be a good consistent source for quality ammunition and reasonable prices. All per round prices were based off the largest quantity available, either 200 or 1000 rounds for most.

price-to-accuracy-5-shot price-to-accuracy-10-shot price-to-accuracy-all-data

As you can see from the data, generally speaking the more expensive ammo shot better groups. However while going from a $1.15 FGMM 69gr round to the $.48 PPU 69gr round only resulted in a ‘loss’ of around .15MOA accuracy (based off 5 shot groups) which leads many to ask ‘Is that extra .15 MOA really worth twice the cost?’. The IMI and CBC 77gr appear to be the best compromise between accuracy and value, they shot some of the best groups (second and third to FGMM 77gr) but cost almost half of what the FGMM retails for.


Now that we have analyzed the data with a Group Average vs Price Per Round, I would like to introduce a new metric to help decide Accuracy vs Price. I made a table with the price per round (in US Dollars) and the averaged velocity for all of the different rounds groups sizes (in MOA). I then multiplied the price by the averaged group size to get a value. I am going to call this value the ‘Price For Performance’. The lower this value is, the better performance you are getting for the price. This PFP metric places more emphasis on the price per round (seeing as we had rounds from $.48 to $1.15 in our testing), especially when most of the ammo’s are shooting similar group sizes.

Looking at the 5 Shot data below, you can see the PPU 75gr had the largest groups by far with a 2.350333 MOA average but the lowest price at $.48 a round. This gave it a ‘Price For Performance’ value of 1.12816. Now if we look at PMC 77gr, it had a smaller group average with 1.531833 MOA but a significantly higher price of $.79 a round, giving a PFP of 1.210148, slightly higher than PPU 75gr. Now I am going to use some data from my own testing of Federal XM193 55gr FMJ (not match grade, but cheaper) it has a per round price of $.38 (on SG Ammo) and I averaged 2.68 MOA group with it. This gives the XM193 a PFP value of 1.0184, lower than either PPU 75gr or PMC 77gr but no where close to the values of our best performing ammo based on this metric (CBC and IMI 77gr, PPU and Aussie 69gr).

By this Metric the following were the ‘winners’ based off this data:

ALL DATA – PPU 69gr with a 0.847947, Australian Outback a close second

10 SHOT – PPU 75gr with a 1.07264

5 SHOT – PPU 69gr with a 0.67592, Australian Outback, IMI 77gr and CBC 77gr in hot pursuit.

The ‘worst’ performers?

Federal Gold Medal Match 69gr, with its high price and marginal increases in accuracy.

Please note, all of this data is based off low round counts, through 3 different barrels and two different shooters. Please consider this when making decisions based off of this data. I look forward to using this metric more in the future as we get more data and post it to help develop more of a ‘full picture’ of which ammo’s consistently out perform their price and which under deliver for their price.

I look forward to hearing your results and thoughts on this metric to decide which ammo will give you the best ‘bang for the buck’!

Barrel Overview using Extreme Spread of Targets

Extreme spread is a strange thing.  In it we compare groups with one another using the outer most shots in the group with little care about the rest of the group.  I’m sitting down with a ream of data in front of me and I think this is just the best place to kick off a big chunk of it.

We have mentioned this before and I think it is important that I reiterate it before you dive into pictures and graphs thinking either this is nonsense or this is gospel.  This is the data as we recorded it.  We didn’t know what barrel we were getting behind when things kicked off.  If we did happen to see the barrel it did not matter as we were doing our very best to provide the best data as we could.  These groups were not fired from a special locking rest and human shooters outshot the Caldwell Lead Sled every time using a bipod and squeeze bag so it was ruled out as a useful tool in this test.  It was not used for any of the groups I am sharing now.

We shared information of each of the ammo types and from that information we compiled barrel profiles.  I was asked immediately following the test which barrel was the best and I had no idea.  I still really don’t.  They all shot 5 round groups that some would brag about.  They also shot groups that many people would sweep under the group rug where fliers go to die.

All the group information below is using extreme spread.  In the near future we will present the same data by way of average to center or mean radius.  I think the two different presentations may paint different pictures but without further ado this is what we found.

Below are the group shots for each barrel.

Ok pictures of groups, now which performed the best?  Well none of them were MOA all day superstars.  That said three barrels lined up and averaged about 1.5 MOA each over 600 rounds.  That is something to be said towards barrel manufacturing today as well as the availability to get ammunition for quality barrels.

barrel-all-groups-average

The group averages were within about a tenth of an inch at 100 yards.  I am sure we can pick this apart and separate certain rounds to make that seem more shiny and chrome but that is not what we are all about.  The same could be said with removing one or two rounds of any of the ten round groups to show how much better the spread is with the elimination of a ‘flier’.  Speaking of 10 round groups.

 

barrel-10-round-groups-average

The ten round groups averaged were larger than the 5 round groups….Shocker right.

barrel-5-round-groups-average

Now bar graphs in the particular use are a bit misleading as the scale makes things look to the extremes.  The intent was simply to show which was the leader in each demonstration.  An interesting bit of data can be pulled from the last two graphs though and it uses the Bryan Litz method of determining group growth between sample sizes.  In his book ‘Modern Advancements in Long Range Shooting Vol 2′ Bryan talks about samples and how they generally extend out using actual shooters to test.

cimg2516_zpslxgxyeok

I think this is a very useful little tool for an approximation of actual group data for the times you have a limited supply of an ammunition type and want to stretch it out.  You can shoot a three shot group and expand it out to the 30 shot  group scale taking it by a factor of 2 and then set up the appropriate size steel at long range and make hits.

Using that line of thought our Criterion Hybrid shot a 5 round group average at 1.39525 if we take that times the constant of 1.24 it comes to 1.73.  The actual 10 shot group average was 1.884 although these groups were fired by two different shooters.  Again we can and likely will dissect each of the ammo types down the road but what you are seeing now are generalities of groups fired at the beginning of each barrels life span.

Below are each ammunition type broken down by barrel and string.

SLW Barrel Shootout – Ammo Data Summary

Yesterday we posted the final set of Chrono and Target data for PPU 69gr HPBT. Now we get on to the interesting side… interpreting that data and processing what it MEANS.

Through the posts about the ammo we compared two major components of the chrono data, the average velocity and the standard deviation. Here is how all of that compares in two, simple to read graphs:

ammo-average-velocity-16-barrels

ammo-standard-deviation-16-barrels

The IMI 77gr and Magtech/CBC both topped the field with an impressive 2639 fps (IMI) and 2637 fps (CBC) average over 60 rounds. IMI also took home the honors with the lowest standard deviation with a low 17.17 fps Standard Deviation with the two Federal Gold Medal Match offerings a close second (17.88 fps for 77gr and 17.94 fps for 69gr respectively)


Also during the ammunition posts we showed group sizes and averages for each individual ammo. We broke those average group sizes into two graphs, one for 5 shot and another for 10 shot groups so that you can easily compare all of the ammo’s to each other. The final graph is all of the groups for each ammo averaged together (5 and 10 shot groups both) and gives a good picture for the ‘total’ accuracy of each round.

ammo-5-shot-group-average

ammo-10-shot-group-average

ammo-group-average

Federal Gold Medal Match 77gr had the best 5 shot group average by a large margin, over .2 MOA smaller than the next closest Ammo. When it came to 10 round groups, Black Hills 69gr had the smallest group average by a large margin as well. It was interesting to see that the winners of the opposite category were rather average in the opposite category (FGMM 77gr had the 4th smallest 10 round group average and BH 69gr had the 7th smallest 5 round group average).

The best group of all of the testing was a .701 MOA group fired with Federal Gold Medal Match 77gr. It should be noted that there was only one 5 shot group over 1 MOA fired with FGMM 77gr. The only other ammo’s to fire multiple Sub-MOA groups were CBC 77gr (3) and PPU 69gr (2). The only ammo that did NOT fire a sub MOA group was PPU 75gr. The only Sub-MOA 10 shot group was fired with Black Hills 69gr ammo

SLW Barrel Shootout – PPU 69gr Ammo Performance

The tenth and final ammo we are posting the data for is PPU 69gr HP BT. PPU is well known for making a wide variety of ammo and their 69gr and 75gr offerings were some of the cheapest rounds we tested.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


 

The PPU 69gr shot an average of 2515.81 fps between the 60 shots fired. PPU 69gr had a fairly average velocity and had an Averaged Standard Deviation over 6 series of 10 shots of 32.58 FPS which was the highest SD of all the ammo’s tested. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.

SLW Barrel Shootout – Black Hills 69gr Ammo Performance

The eighth ammo we are posting the data for is Black Hills 69gr MatchKing HP. Black Hills is well known in the ammo industry and their 69gr load is one of the most popular.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


 

The Black Hills 69gr shot an average of 2583.093333 fps between the 60 shots fired. Black Hills 69gr had a higher than average velocity (kind of expected with a 69gr load) and had an Averaged Standard Deviation over 6 series of 10 shots of 21.16 FPS which was about average for all SD’s recorded in testing. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.

Next are the targets, each barrel shot one 10 round(*) and 2 5 round groups for a total of 58 rounds fired on target. Barrel 1 had the smallest 5 round group of all the testing with a 0.969 MOA target and a 5 shot group average of 1.441 MOA averaged between all 6 groups.  Sadly this was the first 10 round group fired through the second barrel.  We failed to make the correction during the optic swap and the first two shots for the black hills are off paper.  All chronograph data was captured but we had to adjust and fire the remaining 8 rounds.

SLW Barrel Shootout – Federal Gold Medal Match 69gr Ammo Performance

The seventh ammo we are posting the data for is Federal Gold Medal Match 69gr (Also known as FGMM 69gr). This is the first of four 69gr offerings we tested and is the one of the most common ammo’s used for testing AR’s for accuracy. It is one of the most expensive ammo’s we tested as well and I was curious to see if its high price was equaled by high performance.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


 

The FGMM 69gr shot an average of 2608.214 fps between the 56 shots fired out of the 3 different 16″ barrels we tested. 4 shots of the test were lost when the Chronographs battery died (no fault of the equipment, just the operators lack of attention!) FGMM 69gr had one of the highest average velocities (just behind IMI 77gr and CBC 77gr) and had an Averaged Standard Deviation over 6 series of 10 shots of 17.94 FPS which was one of the lowest SD’s recorded. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.

SLW Barrel Shootout – PPU 75gr Ammo Performance

The sixth ammo we are posting the data for is PPU .223 Rem 75gr HPBT Match. This is one of the least expensive ammo’s on the list and has a wide variety of reviews (both positive and negative). I was interested to see how it performed for us.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


The PPU 75gr shot an average of 2516.5 fps between the 58 shots fired out of the 3 different 16″ barrels we tested. 2 shots of the test were lost when the Chronographs battery died (no fault of the equipment, just the operators lack of attention!) PPU 75gr was about average for velocity when compared to the other ammo’s and had an Averaged Standard Deviation over 6 series of 10 shots of 21.98 FPS which was one of the lower SD’s recorded. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11).

Barrel 1 had the smallest 5 round group of all the testing with a 1.476 MOA target and a 5 shot group average of 2.350333 MOA averaged between all 6 groups. We had difficulty with this ammo throwing random fliers for no apparent reason. The chrono data (see above) shows no oddities in the extreme spread or standard deviations of any of the series and the shooters didn’t feel they pulled any of the fliers. We also noted that the PPU 75gr had a distinct smell to it when fired, possibly due to the powder type.

SLW Barrel Shootout – PMC 77gr Ammo Performance

The fifth ammo we are posting the data for is PMC .223 Rem 77gr OTM. This ammo was added at the last minute when I was able to purchase a large enough quantity to get good data. PMC isn’t really known for making match ammo so I was curious to see how it performed.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


The PMC 77gr shot an average of 2341.117 fps between the 60 shots fired out of the 3 different 16″ barrels we tested. PMC 77gr had the lowest velocities of all 10 ammo’s tested and an Averaged Standard Deviation over 6 series of 10 shots of 32.13 FPS which was one of the highest SD of all ammo. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.
