I have the older model Knight Wolverine II and it shoots the #11 caps. It will shoot the loose powders just fine, but the pellets it seems to get a bad delay if I can call it that for a better word.
I rechecked my Wolverine this morning shooting 85 grains of Goex 3f and 250 grain Barnes Expanders at 35 yards. I just grabbed the shooting sticks since that is what I will be using tonight. Both shots touching 3/4 inch high over the bulls-eye.
I think if the deer break cover tonight (the last few nights it has been a waiting game with them) I will fill another tag.
