Well......just when I think I have it all figured out.......an airplane flies over and somebody flushes.
So, I have a '94 that is currently in repair mode (another one) that has a longer mag tube. So, I just cut the spring on that one....plus I leave it a few inches longer for that X-tra push (I'll like get into trouble later for that) load up the mag tube, and Wha-La.....I get the same results. I put 5 rounds in the tube and two feed great....3 don't make it to the pick up link. Ghee...I'm glad I cut that spring.
So, now I look further. I take the forearm off and examine the tube again, examine the follower again and all of that appears good. So, now I mic the tube inside diameter and compare that to the receiver's dimension where the cartridge "exchange" takes place. Well, there's quite a difference in that the receiver is much smaller. I don't recall that dimension off the top of my head...but it's a good 50-thousands anyway. Or at least 25-thousands all the way around the tube\receiver "connection." So...ok...this is not Winchesters first rodeo on this. So, now I pick up the 94 that I have in repair mode and it's really obvious!! The chamfer of the receiver from the mag tube to the receiver on the 94 in repair mode is much more generous than the 32-40 that is hanging up!! In fact, the 32-40 is more "shelf-like" than the angle of the other one.
Now, this would be an easy fix if the barrel were out of the receiver. Yeah.....if.......but it's not. So, I did at first grab a fluted chamfer (I think it has 6 flutes) and just manually began to work it in the receiver hole. It actually fit perfectly......but I was putting chatter marks as I could put any real pressure on it. So, out came the jewelers files and with a half-round file and just slowly worked my way around the hole giving it a nice (or as nice as I could) relatively steep chamfer. So, I got it thru a "first run" and just put the tube back on. I then ran ten rounds thru it......AND.....got only 1 jam!! Not to shabby for the first run!! So, some more time and this time with the magnifying spec's and I will bet I can run twenty thru with no jams. I'm betting that Winchester was counting on nobody ever firing this one. Maybe....maybe not. But at least it is fixable.
