ClackClackBAM Posted October 10, 2020 Share Posted October 10, 2020 Just got back from the range and am wondering if I did something wrong. While it only happened twice and it stopped after I put my shoulder into it, the last round hung up at the end of the mag tube. Shells in question are Federal Power Shok 2 3/4” 1oz slugs. Thoughts?

Evolution Posted October 10, 2020 Share Posted October 10, 2020 (edited) Do you mean that the spring popped the last round into the receiver but not far enough back so the bolt carrier could engage it and activate the elevator? Or was the shell still partially stuck in the tube? Edited October 10, 2020 by Evolution Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted October 10, 2020 Share Posted October 10, 2020 Disassemble and clean your magazine tube well. Do not put oil inside the magazine or on the follower afterwards. Looks like anemic feeding or the shell onto the elevator. The last few rounds in the mag tube feed the weakest. If it doesn’t feed strong, the round can cause the elevator to hang up on the front of the shell. Limp shouldering it can cause the action to slow significantly and the bolt carrier can get hung up on the hammer. 1 Quote Link to comment Share on other sites More sharing options...
ClackClackBAM Posted October 11, 2020 Author Share Posted October 11, 2020 Thank you! I had oiled the spring in the mag tube before I realized I wasn't supposed to, but I forgot to go clean it out. Taking it down for a full cleaning tomorrow. Quote Link to comment Share on other sites More sharing options...
bambihunter Posted October 12, 2020 Share Posted October 12, 2020 (edited) In my experience, limp shouldering, or in my case not shouldering at all will always cause it to fire previous shell and not release the next shell at all leaving the bolt closed on an empty chamber. I was doing some testing with my M3T folder without using the shoulder at all. I could resist with my hands and never had a feed issue, but if I just let the gun fire like a pendulum, it would do as described above. Still, I'd trust SD's knowledge over my anecdotal evidence. *edit* Never mind, I just saw the M4 in the picture. Gas gun wouldn't likely have the same results as the inertia guns...
