3 Inch Barrel on 2.75 Wingmaster

[ReadyontheRight]

Outside of someone possibly loading a 3" round after reading the barrel, is there any safety concern with putting a 3" barrel on an old 2.75" Wingmaster?

It's fine. The 3" barrel will handle 3" shells when installed on a 2.75" receiver, but they probably won't eject, or eject all of the time, because the port is too short.

Number Six wears a new LC barrel with a 3" chamber. It's a 2 3/4" receiver. I've not tried to fire any 3"shells from it but it doesn't cycle fired 3" hulls well.

2 3/4" is STOS.

HTH....

John,

I don't think the size of the ejection port is the problem. I believe the critical difference is in the ejector.

Could be the ejector doing it, but the folks I know who've shot 3-inch barrels on 2.75" Remingtons seem to have had the hulls hang up on the edge of the ejection port. So far nobody has tried filing or Dremeling a quarter inch off to see if it would fix the problem. It was just easier to use the shorter brands of 3's.

I have an original 3" gun that has had the ejector replaced with the 2.75" type (the only way I could get it up and running locally). It will hang Winchester 3" shells in the port as regular as clockwork and others 85+% of the time. I really should have it fixed, but it keeps getting put off since I have 6 other 870's filling in for it. It's kinda handy for practicing clearing a struck case, but putting a rubber band around the reciever works fine.

Using my cheep dial caliper, the ejection port on my newest Magnum receiver 870 (Express SN D810XXXM) measures 2.980" long with the bolt open. The front of the port is .575" from the front of the receiver, the ejector step is even with the back of the ejection port.

So, who has a standard V-suffix receiver handy to measure???

There should be no problem with the ejection port, but the problem is the ejector is not located back far enough to kick out 3" shells on 2 3/4" recievers. A gunsmith can simply move the ejector back and you can then cycle both kinds with a 3" barrel.

I once owned a 3" mag 870 and a 2-3/4" 870TA trap. The ejection port was smaller on the 2-3/4" and the longer 3" shells wouldn't eject even though the barrels swapped fine and this was with shorter "unfired" shells.

Thanks all. Just wanted to make sure before I take it to the range. If it ever warms up here in MN.
