The really hot stuff would cause the occasional malfunction. Messing around with aftermarket springs, etc, increased the number of malfunctions.
I don't have them anymore.
I recommend not going beyond "warm" loads for maximum reliability.
200 gr at 1100 fps, 180 gr at 1200 fps, that sort of range.
I never tried anything over 200 grs because when I'd read / watch reviews malfunctions seemed common.
I'd go with a hardcast 200 gr @1100 fps for woods protection/ penetration. Not a super-wide meplat, either. Just a common shape.
Underwood is normally hot stuff, I've fired quite a bit of it. I'd want 40 rounds with zero malfunctions from the gun before relying on it. You'll need good grip and recoil control. It's not a combination for a novice. (Not saying you are)
