Model 12 feeding
« on: April 11, 2016, 05:28:42 PM »
Is it possible for the magazine spring in the Model 12 to be too strong, even if cut to allow 6 shells in the magazine?  It seems that I often have feeding issues, especially with the first or second round out of the magazine.
Would a newer spring, or the Wild Bodie Tom spring set help?

J, I don't think it would be the magazine spring to strong, to weak can cause problems. Tell me what issues are you having? Are your shells falling out of the gun? Double feed? Gun hanging up and just not wanting to cooperate?  Dusty Boddams

 The action itself feel smooth at least when empty    Often with the first one or two shells the shell seem to block the action or get stuck and not chamber correctly    With dummy rounds that are empty of shot they seem to chamber perfectly and do not hang up

Jorge, have you had that shotgun taken down completely and fully cleaned? Some of these model 12's have been setting for many years with old gummy oil. That would be the first thing to do also when taken down go all the way to the firing pin,pull and inspect it.

 It was cleaned in the fall after our season  and it had not been used to the winter
 However I'll inspect it and see what it looks like

Sounds to me more like a carrier and/or bolt problem. Has the top of the carrier been polished or worn too much? Is the shell stop on the bottom of the bolt worn?

Is it double feeding? If so check the cartridge cutoff. Make sure it's in position to stop the next shell from entering the receiver.

I've had to tweak the cutoff outwards just slightly to make up for wear.   The tip should hang out in the way of the second shell getting onto the carrier ("cutting it off") after the first is already shoved out there.

Good luck, GJ

Me too Joe, that's why I was asking.

I cleaned the mag tube inside.  It wasn't terrible, but a little dirty.  The spring had no rust on it.
After reassembly, I used some dummies with shot for the correct weight and ran them through without an issue.  Now, I'll have to try them with regular shells at the range.

I am not sure how much the bolt and cutoff are worn, I'll have to inspect them a little more.  How obvious would that be?

Of course, might just be operator error.

Next step, off to the range.

Can't say for sure on the bolt, but the hook of the cut off should block the next shell from exiting the magazine tube when the slide starts to move to the rear position. Hopefully your gun just was in need of a good cleaning.

Off to the range today.
Although things started well, I did have several "jams," when the shell would miss the chamber to the right and strike the side of the breech.
So, I shall see if something is out of alignment or weak. 
I was wondering if a weak left extractor/spring could do that.

What brand of shells are you using? The guns can be brand sensitive. Is the carrier un-flagged or flagged? My un-flagged needs AA's or STS's to run, Federals will go to the right and imped chambering. My flagged M12 feeds anything.

I seem to have got darn lucky. My unflagged one runs anything I put in it. I haven't shot my backup enough to know if it will or not. I do have a carrier with flag that someone needs more than I do......

The M12 is not flagged.
I ran federals and AA both new last weekend, and today I ran various reloads.  There was no particular shell that did or did not work.
