Remington UMC worked well for me. I was behind an M1 carbine for the first time when I shot this group/pattern. I was running Remington UMC through my friend's Inland at 50 yards. The first 4 rounds went high left. I made an adjustment in my hold and put the next three low left. After another adjustment, I fired for effect until the RO called a cease fire.
I'd say it went rather well for my lack of ability with iron sights.
