The Magnums, have a heavier action sleeve (a couple of ounces if I remember correctly) and a single gas port vs. the standard two. So if it wasn't cycling it might be from light loads. it wasn't designed for it. Just google 1100 action sleeve, standard vs. magnum.A buddy gave me a 12 gauge magnum 1100 that is in pieces. Supposedly it didn't cycle, so it was taken apart and not reassembled.
I wondered if there is an 1100 expert around that would reassemble and get it working? I live in NWI.
Time for you to pick up a copy of Jerry Kuhnhausen's book The Remington M870 and M1100/M11-87 Shotguns - A Shop Manual.I think this piece is buggered up.
And there's a bar (for ejection?) that came unstaked.
The soft clay pigeon loads are more what I'm referring to. A lot of people tend to get that 100 rd. value box from Walmart. Guilty of it myself.12 ga 1100 magnums run low brass field loads fine. Ive shot several, one was my main dove gun. Heavy Trap or Sporting Clays 7.5s from Winchester.
Over 1200 FPS, maybe a little more than that- cant remember.
Steel dove or softy target loads....nope.
Not with the single gas port magnum bbl.
Most of the time they split and lock up the hammer --Yours don't look that bad. All it does is soften the hammer drop -Couple of clamps and a good prick punch would restake-- Fellow shooter had his come loose he just cleaned and use J.B. weld and clamped -- Worked for him??I think this piece is buggered up.
