Thats like asking what a beautifully woman looks like. Taste differ but he goes my list.

32 preferred but 30 might work, heavy proofs.
Full and Full chokes
Two triggers
Weight 8 plus pounds, 81/2+ even better
I like a stock with 1 1/4 drop at comb. 1 1/2 the max.
POW or pistol grip. I just dont shoot straight grips as well.
