Just got this one and all I had on hand were some hand loads that I did for my PTR-91. These were 150 gr Hornady Soft Point bullets in LC brass using AA2460 and they clocked at 2650 fps-ish out of the PTR's 18" barrel. These failed to fully cycle the action on the M1A as there was no eject. It was obvious that the action partially cycled since it was easy to hand cycle each time. The load shot about 2 MOA at 100 with the open sights and was very close to zero from the get go. I am assuming that this rifle would run better on heavier bullets at full power so obviously I will step up to those as soon as I can acquire some. I already have Small Base Dies which were used to load the above. In spite of inadequate ammo on hand I can already tell this is going to be my favorite rifle. The only other time I have fired this platform is while qualifying on a jungle range in the Philippines on an M14 while I was in the Navy back in 1990. I have wanted one every since and am loving it!
