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.
