I wanted to shoot factory 175 FGMM for function check as this was purchased used. I could only get my hands on a PMAG for now but have a knights mag on order. Function check, check! Shot a decent group at 750 with 2544 avg speed.
I then loaded the once fired brass bumping the shoulder 5thousands. I loaded Fedral match 210m primers and 41g of IMR 4064 with a 175g Smk.2.80 oal. Shot a .55” 5 shot group at 100y. I feel the load may still be a little hot as the primers are pretty flat. and the is an extractor mark. This is 1.3g under by bolt gun load.
Anyone with a GAP -10 have a pet load?
