I picked up a browning gold sporting clays gun in great shape. Its a great gun except it jams a lot. It slams the cartridge into the side of the barrel. Sometimes i can shoot two rounds of skeet no problem, other times it has this problem five times in a single round. The average seems to be one out of twenty five. I've read that they are finicky on oil, and CLP was recommended and that's what I use. I tore the whole gun apart and cleaned the recoil spring mag tube. Any help would be greatly appreciated. Thanks in advance. I should also mention it has the light gas piston and I'm using 7.5 shot winchester factory ammo.
