Was wondering what factory ammo everyone uses. I've tried remington umc 45gr. hp. and could not get a grouping at 200 yards. (When I say could not get a grouping I mean under 2 inches). at 100 I held less than an inch. With winchester I hold a little better grouping at 100 and at 200 1.25in. grouping. Same 45 gr. hp. At 100 yards the remington shoot almost 2.5 in. higher than winchester. Havn't tried any other brands yet since the winchester seem to be very consistant. Was just wondering what others shoot.
