I just purchased a mid 80's Rem 1100 Magnum from another member on the EE. The gun is in decent condition but I can not get it to cycle any 2 3/4" loads except for slugs. It has a 26" vent rib barrel which was cut down to 18.5". The action is pretty clean with no large deposits of carbon on the piston or in the port opening. I have already ordered new springs for it from Wolff and I plan to replace the rubber "O" ring in the gas system before my next outing. A few questions:
-The barrel is marked "3" shells", not 2 3/4" & 3" which is what I'm used to seeing. Does this mean the barrel is not designed to function with 2 3/4"?
-I have heard about opening the gas port up a bit, is this an option that might resolve the cycling problem? If so, anyone know how to go about it?
-Did cutting the barrel down limit this barrel to 3" loads only?
Any help would be appreciated. I am considering sending the barrel to Vang for a work over but am unsure if he would solve this issue or if I need to get it cycling properly before I send it. Thanks in advance for any advice guys.
My guess is the gas ring. If you don't form a good seal, you won't reliably cycle the action.
As for the barrel, it is likely from an 11/87, shouldn't have an affect as most parts are the same between the 1100 and 11/87, just don't run 3" rounds thru you 1100.
When I purchased mine, used, I took it to my smith and had him replace worn parts. Cost me like $40.
I love my 1100. Points well, easy follow up shots.
Thanks for the info. My receiver is marked 1100 magnum so it should be OK with the 3" shells.
