Ok guys I have a 10 ga BPS NWTF 24",shooting magblend 5,6,7's. I,ve shot jebs .680 got 168 in 10in circle.Kicks .685 181 in the 10,Indian creek .690 about the same as Jebs .680. Then jebs sent me a .695 got 204 and 207.A friend of my has a NEF 10 with a factory .720 choke non ported he let me try. I got 250 hits in the 10. Indian creek traded me the .690 for the .710 but havn't got to try it due to the weather. If anyone can tell me what is going on with this gun I would appreciate it greatly, for I feel this thing should be getting over 300 in a 10 inch circle.
