The dreaded Marlin jam

full against the case stop - there is nothing in the action that guarantees the case is full back against the stop. Only that the nose clears the mag tube. If the case gets crooked in the lifter it won't chamber. Pic doesn't look to be 357.

What exactly are you saying to me here??

The cartridge stop is so named why??

I can assure you your looking at a 357 Mag dummy. Case trimmed and Lee 358-158 seated to crimp Groove.

Case does NOT clear mag tube. (Whole
Reason Im doing this)

Cases that make it out of mag tube feed perfectly.

Can you get a photo of the cartridge where it is stuck? Maybe thru the loading gate?

Your last photo shows where the cartridge sits on the carrier. The lever should not interact with the cartridge in any meaningful manner.

Is the lever really that far open when the carrier drops full-down and and exposes the magazine? With my 30-30s the cartridges don't pop out of the magazine until the bolt is almost locked. The head of the lever catches the carrier at the front and pulls it the last little bit down as the lever snicks closed.

In my pics the lifter has only just started to raise to feed a cartridge. I believe that the rim of the cartritage is hard impacting the lever, below its relief. BEFORE it reaches the cartridge stop.

Yes, but that isn't where the lever nose is when the cartridge first comes out of the magazine toward the lifter stop. What you're showing isn't what's happening, the lever is almost horizontal when the cartridge pops back...or should be. If the cartridge rim is hanging up on the lever, it isn't doing it at the point you indicate. Time to put some Dykem or sharpie on the lever nose and see where the actual hangup is.

yep, I could not tell the number of times my eyeball assumptions proved wrong when DyKem was applied. I have also learned not to marry my assumptions as often they are wrong.

What exactly are you saying to me here?? pics I got were a bottle neck and your hollow point cast. Are you sure the mag spring/tube are OK? The spring should pop the rnd all the way back into the stop. The carrier is a gate, when it clears the spring should forcefully do so. Every once in a while my 30/30 bounces the case crooked onto the carrier. Kinda got to shake it into alignment to close the bolt.

I disagree If id posted large pics to see all we would not see areas of issue clearly enough. These parts are on top of receiver so yes approximations. But lever loop is parralell with where stock would be, so "dingus" that engages bolt is close to actual position on action.

I have everything in white so I will try dykem later tomorrow aft docs.

I dont think we are looking at same pics or I seriously do not understand.

No bottle neck cases in my pics at all.

No hollow points either!??


As mentioned if bolt & lever removed. Dummies slide forcefully from mag tube a foot out back of action!! Seems plenty smooth forceful & free. With bolt in but NO lever. Dummies freely & forcefully eject from mag tube. Onto carrier, stopping @ cartridge stop.

I do see how crooked would impede proper movement.

Maybe dtkem will show something more.
Thanks guys

Well boys...
Thanks to Walks I am pretty assured I have a 357 Lever. He showed the differences biggest being thickness and mine is thin like his.

BUT, as you can see, this is proper parts position and my case does in-fact impact exactly where I have tjought.

Here is pics where I have removed gate to gain ability to see.

Looks like I need to alter the length of the relief so the rim can pass. If It causes another issue I can add weld and shape back to orig shape...

Any more thoughts before I do.

Here is the lever farther open

This is using a factory loaded Winchester Blk Tallon.

You can see the rim is stopped by the lever not the cartridge stop. Without the gate case can go where it belongs. But never with gate in place maybe not even with the alteration I feel
Is needed.

2nd pic down, how does case get there with the lever just barely open? Carrier should never drop that low that early. Or are you just closing lever on an already dropped case? But then the carrier should be up to the chamber ready for the bolt to push.

Thats the way ever lever I ever owned works. The rim of the last Cartridge, stops at the gate. I honestly have never seen a lever function differently.

The lever never completely raises until you actually start to close the lever.
On the bottom of the lever there is a cam that sightly raises the lifter blocking the mag tube. THIS is where it grabs the nose if my bullet that cannot travel to the cartridge stop.
