Remington Converson Blows Up

He used a .45 cal round in a .44 cal pistol.
If the bullet cannot get out the pressure has to go somewhere.
Also if they were hard lead they might not have made it through the forcing cone in a pistol that was designed for soft lead.
Naturally, I can't say for sure but that is IMHO.
 
The idea of two bullets in one case, as a possible cause, is a revelation. I'm not sure if two 225 gr. bullets could be seated in a .45 Long Colt case without being noticed, but today's presses have good leverage and it might be possible.
Anyway, it's a revelation and a warning to keep your dies clean, especially with lead bullets and any kind of sticky lubricant, such as Alox.
Or it could have been a double charge of powder.
Mystifying. I hope the shooter can remove the rest of the cartridges to identify and weigh their powder.

It's not unheard of for reloaders to finish a batch, then pour the powder in their measure back into the wrong container, such as pouring Bullseye into a 2400 container. Later, he goes to reload with 2400 and pours the 2400/Bullseye mix into his powder measure, failing to notice the contamination.
This has happened more than once.
It's why, before I pour any powder into my powder measure, I place all other powder outside of my reach. Then I pour the intended powder into a Dixie cup and look it over. It's a moment of safety that could save you or your gun.
 
I'm betting over charged case.

Bear Creek Supply 225 gn RNFP ahead of 5.3 grains of 700-X

Bet you a good cup of coffee that load was 10.6 grains or more, probably more. 6 grains is a maximum load.
 
its a tricky thing this type of situation. used to have a photo of a blown up brss framed remington that had been loaded with bullseye powder instead of pyrodex...


the way the original post was listed, it sounded like one of the original 6 shot conversion cylinders where the chambers were slightly angled to allow the rims of all 6 cartridges not to interfere with eachother andmakeit a 3 shooter.
 
.44 C&B has a .450 bore. .45 cast bullets are .452, no biggie

But you are still putting a .452 diameter bullet in a case designed for a .429 diameter bullet and then jamming it into the cylinder. I don't know anything about these conversions, maybe this is standard procedure, but the above just sounds wrong.
 
I have an R&D conversion in my 1858 and have fired countless rounds out of it. I'll bet on a double charged reload. I reload my own with Trail Boss these days and have never had a problem. Those cylinders are very well made.

What are you talking about?? Where does a .429 case come in at? The cylinders are chambered for the .45 colt round, not a .44-40/special/magnum/russian(.429)
I don't know anything about these conversions
I can see that. The standard size round ball used in a .44 C&B revolver is anywhere from .451 to .454. I use .457s in my dragoon .44s. This is why a C&B .44 is converted into a .45. The bore is the same. There is no problem with the conversion. He said he was using hand loads. My guess is, that is where the problem lies. These conversion cylinders have been around a long time and are quite popular. First time I have seen this type of thing happening.

Wish this wasn't being titled like this all over the net...:rolleyes: It has nothing to do with a conversions fault.

This was almost certainly caused by 2 bullets being loaded into the case...a double charge maybe..but his load was very light so even a double charge (of his load) probly wouldn't have done this.

I can't beleve how many people don't know that the "44" designation is NOT the same as the 44 (.429) of today...all of these Remingtons ARE 45's...NOT 44's

I just had a guy bring me a bunch of rounds (to reload) that he had been firing through his Rem conversion...when I looked at the cases they were all expanded clear out and I looked at the headstamp and they were 44mags!!!!!!!!!:eek::D Guess the "44" on the barrel confused him too..lol Good thing all that pressure just blew by or he could have had troubles.
 
On one forum, the owner of the gun in question speculated that the cause of the explosion could've been a small charge/large case detonation. One reason or another I would say the problem was with the loads.

As stated earlier 44 c&b is .45cal.

In the old black powder days folks measured things all kinds of differently. Some of it is still labeled weird like how .38 special and such isn't .38cal its actually .357cal. ;)
 
I bet he loaded it with 10.6 grains of powder, which is a double charge and easy to do.
You can't doublecharge blackpowder, it wants to be loaded to the rim.:)
 
"If ya want a .45 Colt revolver , buy a .45 Colt revolver!"

AMEN! I don't understand the point or purpose to the conversion, but each to his own
 
Thanks for the clarification. I did not realize the conversion was to a 45 colt cartridge. Made an incorrect assumption that a .44 C&B would be converted to 44 Special.

When you convert it to .45 Colt, it is a .45 Colt revolver. If the problem was a double charge or a double ball, this could happen to any .45 colt revolver whether converted or not. IMO it has nothing to do with the gun or cylinder, and everything to do with the cartridge. I load .45 Colt with BP, Pyrodex, or Trailboss to make sure that the odds of this happening to me are slim to none. Actually, I'm looking for a used conversion cylinder for a Uberti 1858. Anyone scared out of keeping theirs, please send me a message. ;)
 
Gentlemen, I am new to the C&B revolver arena. I purchased inexpensively a '58 Rem brasser & '51 brasser on gunbroker. Can't remember which one I did this with, but I doubled-balled (inadvertently) one of the chambers over 18gr of 3f and just shot it out. It was no big deal and certainly didn't seem to cause any problem.

Perhaps I'm not paying attention to the details of this case, but what was the cause of this malfunction?
