outerlimits Posted June 29, 2008 Share Posted June 29, 2008 my first JP barrel-finished the build and went to the range. did the barrel break-in, adjusted the gas system and got a rough 100 yd zero. then, squeezed a 3 shot group of less than .4" with 55gr NBT's. 200 yd groups still sub MOA. gotta like it!

outerlimits Posted June 30, 2008 Author Share Posted June 30, 2008 outerlimits... what does that load chrono at? didn't drag the chrono out, but will this weekend. noticed my poa changed on the bdc, so i'm guessing it's going faster than the old barrel. that load was going 3,039.
