Crimp Jump?

[tnieto2004]

Has anyone ever had crimp jump cause a stuck bullet in a revolver barrel?

Last week at my range I had a shooter with a Ruger LCR shooting aluminum cased 158 gr rounds and 2 bullets jumped forward and jammed the cylinder.

I don't crimp light loads in 357 Mag. Last year I had a couple of 158 grain lead bullets creep out of the cases and jam the nose of the bullet against the rear of the barrel. I just pushed them back into the case with my finger.

I can afford to use a weak crimp for range ammo using fast powders. For ammo carried "for real", I take a lot more care.

I guess they were just eager to get where they were going.

Nope. I put a pretty decent roll crimp on all my 38/357, though. Even the wadcutters. I think it helps them find their way into the chamber.

I haven't split any cases, yet. I notice with my wadcutter nickel brass, a fair bit of the roll remains after firing, sizing, and even after flaring! So when I reapply the roll crimp, it's not working the edge of the brass that much.

I wouldn't think that a bullet that jumped its crimp would stick in the barrel but it can creep far enough to extend beyond the cylinder face and prevent the cylinder from turning. Had that happen recently with some very lightly crimped 158gr LRN bullets being shot from a S&W model 36.

I'm Wondering if I had one jump, then I fired the round with the bullet barely seated. There was powder on the outside of the case and I felt a good bit of powder burning on my hands. The bullet made it about an inch down the barrel

That doesn't sound good! Are you shooting 38sp in .357? I'm just wondering how the bullet could move forward enough to greatly reduce pressure w/o jamming the cylinder.

 

[tnieto2004]

No, just through my .38 S&W 642. I'm wondering if the primer ignition popped the bullet out and the powder blew behind it. I'm at a loss. I didn't put much crimp on these loads.

 

[MtnCreek]

It could have been a squib with the primer sending it part way down the barrel, but your comment about the powder burning your hand doesn't make sence. I like a pretty heavy crimp for revolvers. The heavy crimp seems to give more consistant accuracy and SD's, at least for me.

Sure glad you didn't pull the trigger again!

 

[tnieto2004]

Ya, I have no idea why the round did what it did..

I just don't think you have much to brag about. While I've been forced by circumstances to have weapons exposed to sever mud and freezing conditions I've always did my best to keep the weapons clean enough to function. In so doing kept squad members healthy. If that is the way you intend to treat your weapons, you might want to consider owning such weapons.

I've never had one actually get stuck in the barrel, but I've had them jam up the cylinder pretty good on a couple of instances.

Huh??
