Wrong place, but I'll answer anyway.
I have one drilled 50* 4 3/4" 20* That I like to use on longer patterns when I need a strong entry angle
I have a 2nd drilled 50* 5" 65* That I like to use on shorter sport patterns or on most house shots. Both are OOB. I haven't had the chance to test either on a sport shot yet, but hopefully soon.
