well ive been seeing a couple of posts about bb gun improvements. but the one were u put 10 BBS in the barrel is crap! ive been doing that and the bbs up front go slower and dont shoot worth crap! i have a crosman 760 pump and wat i do is take a 1/4 inch thik ball of tiolet paper and put it in the chamber then push the bolt forward. then i shove about five to ten #6 lead shotgun bbs in. then i push teh bolt forward. then i put a 1/8" wad of tiolet paper in afeterthat. then push the bolt forward again. now ur ready. i pump my gun up 30-50 times and get a 10" spread at 25 yards and all the bbs are evenly spread and go the same spped as the other bbs in the barrel. the bolt may b hard 2 push forward but it works as good as h*** when u use it. i love it and it works great and shoots fast. and the bbs dont cost much at all. well good luck. but i am not taking responsibilty for any injuries, damage or anything negative. but 99.9% of the time that wont happen and i have been doing it for 3 yeaers now and nothing bad has happedn.

That sounds risky, at the very least you're going to blow your seals. There are pellet shotguns out there in the air rifle ranks, why take such chances?
