I'm not a big fan of Wolf ammo. I've tried it in several different gun/caliber combinations, and have always had accuracy, or functioning problems.
The one brand of steel cased ammo that I've had excellent results with both in accuracy, and functioning is Silver Bear.
I've shot tons of it in a Bushmaster(223), and also in 380, and 9MM pistols. It's always been very consistant, extremely accurate, and 100% reliable with functioning. The Silver Bear 62g HP 223 ammo works very good on groundhogs through the Bushmaster, and the 92g HP in 380, as well as the 145g HP in 9MM also give great terminal performance on critters like possums, coons, groundhogs and such.
