So around a year and a half ago, I got a wild hair up my ass to make a matched pair of tac6's. 1 in an AR15 platform, and one in a bolt gun/PRS style. The ar came first, since it was the cheapest to build. Barrel, bolt, upper and other legos to add on and I was done. So, after looking at other load data on the different forums, I found a reliable load for a 95gr SMK with 30.2gr of Lvr and said ok for the AR...Took it out to Nebraska, validated that the 95gr smk's don't like varmint cong and called it good. After scrounging around the house to come up with the funding, I had the reamer cut from PTG, picked up a chassis, got a TL3 and ended up buying a Rock Creek 6mm barrel w/a 1-8 twist. After finding a new gunsmith down in Trinidad that is of the old school values on the lathe, I paid him to chamber the barrel. He timed everything up for my lil yeetle yee, and here is the result...Still working on the barrel break in, and had to do the shoot 1 clean, shoot 2 clean...etc...Scope sight in was the middle target, or large diamond with 5rds of 30.2gr of cfe223. Both top small diamonds had the same 5rd cfe load, along with the lower right diamond. Orange dot and lower left diamond were the lvr load. All the velocities are at the bottom. Still can't get over how dirty cfe is after 5 shots...
Just a note, all loads were on a Dillon RL550B...
