Not much overboring. The "pros" shoot whatever their sponsor mfg. gives them. Most are already .735-.740. Some may have a little forcing cone work done. Chokes and choke tubes vary from fixed mod/imp mod/light/full for guys like Wendell Cherry to whatever screw-in mfg sponsors them.

All the rest of us are somewhere in between. I'm in AA and shoot 1500-2500 registedres targets/tournaments a year, and 6000-8000 practice targets a year, and I shoot a 32" DT-10 with Trulock chokes. No ports, no adj comb. A little added weight under the forend, it weighs 8lbs. 10 oz.

Works for me. http://www.winscoreonline.com/view_resul...mp;class_id=All
