I went to the range today armed with my new Jack Carbine AR and a bunch of different ammo and went through all of them at 400yds and came up with two winners. They were the Nosler Custom 77gr HPBT Match Grade 223 and PMC X-Tac 55gr. Both were about equal and each had one flyer out of 3 but it was probably me and not the ammo. I'm real happy with the results and want to reload some to match these two. I've got 4 different load manuals but wondered if anyone here has any input on what powder and data along with the COAL that they used to match these two different ammo brands. Below is the 8" target I shot at 400yds with the Nosler as 'N' and the PMC as 'X'.
