[QUOTE="jrock, post: 2595957, member: 78569"] You are correct. Looking to post more of the testing that was done. Some of the other data was with 129 grain bullets and suppressed vs. unsuppressed. Just as a teaser. Before doing the test, I did some research for published data on MV changes in barrel lengths. I couldn't find anything in the PRC case type. On the charts I did find, for larger bore rifles (.223 aside), 20" does seem to be the starting edge of the muzzle velocity "cliff". That doesn't mean you will loose all of it below 20", just more per inch. I wanted to find out how much more per inch with the PRC case. [/QUOTE]
