Sorry if I come off as lazy but I would appreciate a good place to start. I have a Xtrema2 with a factory full, and I also bought a HS Strut .685 undertaker on clearance last year. It seems to shoot pretty well, sorry no numbers on shot/pattern count. What have y'all found to be a good combo as far as load/choke. Any help would be great. I'd like to start shooting now so I'm not rushing when March rolls around.
