View Full Version : How dangerous is a revolver that will not reliably index?

Wondeirng is this is a minor nusance that can mostly impact reliability or accuracy, or can a round touched off while the cylinder is not in line with the barrel lead to a catastropic failure?

I've always assumed that if the chamber was "in-line" enough for the primer to detonate, then the forcing cone would allow the clyinder and/or bullet to realign, possibly at the expense of spitting some lead and loosing some accuracy. Now I'm not so sure, especially if I imagine a bullet with a large meplat. Seems like in some cases, this could cause a pressure spike.

I've seen split forcing cones with pieces of shrapnel blown out and taken guys to the ER to have metal fragments removed from their hands, wounds cleaned and stitched up, tetanus booster administered.

I'd say that's bad.

It's very bad, and might have been worse. I suspect it happens with very powerful magnum loads and/or with loading practices so unwise than they cause a brief hangfire. What is barely noticeable in a rifle could become more than noticeable with rapid double-action fire in a revolver.

I've been standing next to a guy with a badly timing taurus 32 at a match.. Thank God for wearing wrap around eye protection other wise I would have been blind by now.
Had to call an emergency cease fire and have him removed from the line.. Big chunk of lead stuck in the glasses and bloody cuts to my face..

If the pawl and/or ratchet are worn enough to cause the gun to be out of time, return it to the factory for service NOW. If you continue to shoot it that way it will certainly not get any better.

I got splattered from 30 feet when I was ROing a state level IPSC match. That evening I dug it out with a pair of tweezers. Digging it out didn't hurt as much as when my wife poured alcohol on it.

If it's American made, I would contact the factory.

As others have said, it is a serious issue that should be addressed before firing the gun again. In addition to lead/shrapnel splatter the gun is firing without the cylinder being properly locked in battery. This will turn a simple timing job into a replacing major parts job.

If your brakes are "iffy" in your car, maybe "you" find them acceptable, since they do stop the car, You have been driving it for some time & know it is needing brakes, but just have not fixed it or take it to a shop to have it repaired yet...

Would ya let your missus or a son/daughter use the car with the brakes not quite what they should be?

If ya have such a firearm with issues as ya post about... Go get it fixed. Or, do something to make the issue not be an issue to anyone.
Particularly since it could not just cause issue with the shooter, but anyone nearby. No one needs "that" on their mind for the rest of their lives if something was not to work out right...
;)

Maybe this is just one of those, "Hypothetical", or ""what if" questions in your OP, but if it is not, please get it fixed. I think you will not be the only one happy ya did, if something goes wrong...

G'Luck!

Picked lead out of my hand for weeks 35+ years ago when the 22 revolver didn't index correctly.

Please get it checked out.

I wore out the timing out on a 629 (44Mag). The day I noticed I shot a few more rounds then usual, the gun was dirtier, and the more I shot the worse the groups. Got home and started to deprime the brass ..... Never seen the firing pin mark offcenter before. LOL

Using the bullet to align the cylinder to the barrel is Not good for accuracy! LOL

No damage was done and a new aftermarket hand from Brownelles fixed it. They have one that is longer and wider in the white.

I did not shoot it until it was fixed. The offcenter primers gave me pause for thought. The loads were 1,000 ftlbs at the muzzle.

I had a cheap imported revolver, in 38 Special that had a sloppy locking bolt. the cylinder was off by just a few thousandths of an inch but it would "spit" lead out of the cylinder gap/forcing cone enough that a person standing 10+ feet away got sprayed enough to sting. Good thing he was wearing shooting glasses. I can't imagine the force applied to the forcing cone every time the gun fired and fortunately I stopped shooting it before any lasting damage occurred. I put the gun away and 20 years later, after I knew a bit more about guns, I replaced the locking bolt and peened the slot in the frame a bit smaller, fixed it...

Shooting a Martial Colt DA .38 long colt with borrowed .38 special ammo. The third round blew 1/3 of the forcing cone into my support hand. The primers dragging and the worn lockwork conspired against me.

For a cylinder to index, the hand turns the cylinder and the bolt engages the flute in the cylinder. If a cylinder is out of index, there will be drag marks on the cylinder caused by the hand being either too long or too short.
Is a simple fix if you are a 'kitchen table' gunsmith - otherwise pay the freight and have a real gunsmith replace the hand and possibly the bolt spring (either weak or broken)

Years ago I shot a "warm-up" PPC match next to a shooter with a badly timed revolver, nothing serious but blood was flowing by the end of the match and I spent the next few days (at a national match) picking lead shavings out of my left hand. I told him about it and when we reported back to the line for the next relay he said his team "armorer" had assured him his timing was perfect. I sat out the next relay!
A very minor misalignment is detrimental to accuracy, a bit more generates bullet shavings outside of the forcing cone and can be somewhat dangerous and at the very least annoying. Only a little more misalignment can be very dangerous to the shooter and anyone nearby.
With all due respect your assumption is very wrong, any timing error that is apparent to casual observation is dangerous. Please suspend shooting of this revolver until it is repaired.

This is what I was wondering about...so it can actually cause a KaBoom?

You haven't lived till you've had a cap & ball revolver chain fire! Both times I've been there the revolver survived. Creepy.

Had a firing pin strike on the edge of a large pistol primer. It did not fire. The old model Ruger SBH has to be loaded correctly. If its not, it possibe to be out of time. After this, i loaded it correctly. I think a fully loaded 44 mag may do some damage.

The photo was just to make you think "Safety First" . I dont remember the cause.

A revolver chamber that doesn't correctly index in line with the bore is akin to holding an ice cream cone, raising it to your mouth but hitting your forehead . . . .

Like trying to stick a fork in your mouth but sticking it in your eye?

LOL. Good analogy & easy to picture in ones head. Made me laugh a bit anyway.
