HI all, My first time to post so hope I don't miss any protocall. I Live in the beautiful Willamette Valley and enjoy enjoy shooting whenever I get the chance. Grew up with guns and want to pass that on to my own family, hopefully for many generations to come. I enjoy all firearms but am mostly interested in things that have some older history attatched to them. Question: Recently a Remington 550-1 came to me and I've been enjoying it very much. First 500 or so rounds, no problem. Then it started jamming really bad, like every other shot! It always ejects the old shell just fine and the new one is not jammed either. The bolt sticks back and I have to pull it back the rest of the way. This frees it to move forward and load the fresh cartridge. I've noticed that a few times even after I've unjammed the bolt and the new round is in, it still isn't cocked even after going through the full cycle (albeit manualy) and I have to pull back on the bolt, eject the good round and chamber another. I've given it a basic clean but the problem still persists. Sure would like to get it up working. It's a fine little rifle. Any thoughts would be appreciated. Thanks!!
