45 colt destroyed

[flyingmonkey35]

I was out in the desert shooting my Ubriti cattleman 1873 colt.

When this happened.



It appear s the cylinder broke in half.

Barrel is empty no bulging present

I was shooting reloads. 45 lc 200 grn swc PC. 6.4 grains of IMR BP

This happened after round 80.

No one was hurt. Just my pride.

Thoughts?

I plan on giving Uberti a call to see if they want to test it and the metal

[flyingmonkey35]

Oh this has less the 1k rounds down it.

[enfield]

you meant to say, most of the cases had 6.4 grains of IMR BP in them.

[CastingFool]

That's a bummer, glad you weren't hurt.

[DeanWinchester]

Double charge?

[flyingmonkey35]

While a double charge is always possible . that wold have put at at 13 grns. Max for this was 9. That would put this at a over charge

[country gent]

Several things could have happened here. 1) a double charge of powder, 2) a timing issue where the cylinder wasnt fully alighned with the barrel, 3) an under charge leaving a bullet in the bore ( normally bursts or bulges the barrel tough.
Did anything seem odd or diffrent on the rounds before this on or this one light report recoil or excessive report and recoil? Larger than normal muzzle flash? Were the rounds grouping accuratly up to this point? Anything that stands out or seems unussual during this session.

[flyingmonkey35]

Not really.

I was shooting at a duleling tree. About 25 feet 6 in plates and hitting more then missing. Nothing felt odd at all.

Even the last shot was a bit more of a boom then normal. But not handnumbing or anything. You can see that the two rounds next to it were shredded but did not fire.

One still had the projectile still In place.

I searched but could not find the top half of the cylinder.

If you guys want close ups let me know.

Should I bother calling Uberti? The gun is only 4 months old.

[country gent]

Yes contact uberti I would e-mail rather than call. Include the pictures and all pertinent information. There may be an issue with the cylinders also. Give them all the info including number of rounds thru the firearm. Flutes cut to deep or off center could result in a thin cylinder wall. There are several issues that could affect this. Include fiorearms serial number as this will allow them to track what stock was used and records checked on materials.

[flyingmonkey35]

Thanks, I'll post relpys

[DeanWinchester]

Not sure I'd mention they were reloads unless I had to.

[John Boy]

How many reloads on the case in the picture?
May want to look at the case for indication of weak brass because of the separation below the web

Did you find the bullet from the exploded case?

[flyingmonkey35]

Nope. Couldn't find it.

[flyingmonkey35]

Unknown for brass reloading times. I inspect each piece before

[DeanWinchester]

Crazy question but....it didn't happen to be a ballon head case??

[JHeath]

Hmmm . . . probably a multiple charge overpressure caused by concentrating 5 loaded chambers into a posting on the single-shot forum.

[rondog]

Did you say that was black powder? Is that what BP means? I thought I'd read you could pretty much use compressed loads with that in .45C, but I've never loaded any .45C with black powder.

PB

Named for the porous base structure of its grains by which the burning rate is controlled, PB is an extremely clean-burning single-base powder. It gives very low pressure in 12 and 20 ga. shotshell target loads and performs well in a wide variety of handgun loads

[flyingmonkey35]

Corect IMR BP. Ball powder. Smokeless

[flyingmonkey35]

Dang it pb peanut butter.
