Well as far as just plinking-they were alright for me.
I might get shot for saying that, but hey :twisted:
My Ultra shot them ok, and ejected them over my shoulder. I have yet to try to put them on paper, but from my rough guess I was shooting them within 3". Like I said I haven't tried to group them, but for just plinking were accuracy isn't needed 100 percent, I had fun with them. Not a bad idea if you want to at least get the feel of you rifle. Pretty dirty though. After shooting a few and then going back to brass, the spent brass got stuck in the chamber.
I like good ammo though, and would rather spend my money on brass rounds that will group well under an inch. Just my 2 cents.
