I don't hunt with one - yet. I just picked up my first 10mm last week. I don't have any reloading components or dies for it yet, either, so I bought a case of federal fusions. I've seen great results with the fusion line of ammo and decided to give it a whirl since I don't have time to hunt down components for 10mm as of now. I've got it zeroed in and it'll do 2.5" groups at 50 yards with me resting my arms. If I rest the gun on anything, it'll do 15" groups at 50 yards. I look forward to giving it a try on whitetail this season. I do not like chasing brass though, and it's throwing brass 15-20 feet. We'll see how it all plays out. Oh......it's the Springfield 1911 TRP 5" with trijicon RMR.
