Re: georgia arms
Mixed results, About 2 years ago my buddies and I purchased about 30K rounds of 223 and 308. The 223 canned heat yeiled about a 3"MOA regardless of the AR RRA DPMS JP Pre. 16 to 20" tube all with a 1:8 twist. The Match 223 would shoot consistent sub .75 groups to 300 yards in most gas guns. Had silver primers, a cannalur and 68 Grain HP Boat Tail Bullets. No idea who makes those. Appeared to be reloaded with 748 24.5 grains of powder were used.
The 308 canned heat 150 grain was about a 2 to 2.5 MOA bullet in most Gas guns from 16 to 20 inch tube. The 169 match 308 was about a 1.25 MOA out to 200 yards with a gas gun. Perfectly fine ammo for most 3 gun matches. No failure to fire or feed or seat with all rounds.
I have not been able to duplicate the origianl 223 68 match load, I wish I could. Recently one of my buddies went back for some more 223 68 match ammo and although he got great results with the first batch from 2 years ago the replacement ammo did not perform as well as the original stuff.
Hope this helps
