What do you consider great, and what are you using for powder?
I run 25.5 grn of Reloder 15 and CCI Small rifle primers, (I like the magnum primers when I can find them

less deviation in velocity,) but standard primers work fine.
This is the only combination if come across that matches GP90 ammo in group size and point of impact, and I've tried lots.
Groups, looking at my stack of targets beside me, they average about 1.25 at 100y for a 5 shot group.
Lots of times, 4 shots in a small cluster and that 5th shot and inch away to pi$$ me off. Pretty good I think for a combat rifle not tricked out with match grade barrels or triggers.
Point of impact was point of aim, the centre of the target, not 2 inches to the right like lots of commercial loads do, when rifle was sighted in with GP90 ammo.
I've had some good luck with 77 sierra match kings as well, 24grns of RL15 behind the bullet, but the point of impact is different.
I feel that the Sierra 65 SBT gameking works best for me.
