To start with I love this forum. Heres my situation.. Ive got an 835 with a 24in ported barrell. Ive been hunting with a .695 undertaker in it with win xtd range 6s and had an awesome pattern. But, since they arent an option and none of my birds have been killed past 35yrds Im swithching to lead. Last week I bought a tg ssx .670 and deep cleaned the barrel. My first shot with the clean barrell was win xx mag 3.5-2 1/4-6 and got 121 in 10" at 40. Then I shot in this order,win hv 3.5-2-6 (104 pellets),win 3.5-2-5S (86 PELLETS),FED TURKEY THUG 3.5-2-6 (78 PELLETS)!! I was shocked at the low count of the thugs and later noticed the descending number of pellets from each shot. I'll shoot some more to know for sure, but does anyone believe a clean barrell is that much better than one with 3-4 shots through it?
