45 colt destroyed

[freebullet]

O my. I'm glad your ok, and thank you for sharing the pics & experience.

Did you charge the cases from a loading block?

What type of press if not a single stage?

I know of a gentleman that blew up a new Browning high power within 22 hours of owning it. He shot some unknown source reloads. He sent the gun to Browning, they gave him an estimate to fix it for 200$ more than a new one. He pleaded with them and they wound up selling him a new one at dealer cost. They kept his old one for display. Their best guess was a squib load.

Can you show us a photo of the can that this IMR BP Ball Powder Smokeless came out of that you describe ?

If your powder was indeed PB, it is not a Ball Powder, it is an extruded , single base powder .

Over the years I have seen several colt and colt clones come apart just like that. On some the topstrap is totally gone. Most of them have been suspected double charges but one was factory load so double charging shouldn’t have been an issue. The easy answer is always it’s a double charge but I am not sure that is always true.

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

Louder could be just the extra gasses but if it kicked more than normal that would seem to indicate an overcharge.

Kick was gun going kaboom!

OK, didn't know this was smokeless. The original post says "BP", and I know loading .45C with black powder is common, so I just thought......

I shouldn't try to think.....

Lee loadmaster.

For colt brass I do it in two stages.

I deprime / clean / handprime

Then load starting with powder. Bullet. Factory crimp.

I'm with Ben, can you elaborate a bit on this powder? A picture is worth a thousand words.

Did you use IMR PB data? It is not the same powder, I don't believe.

I thought it was the same (or at least very similar). Just imr started putting their name on it at some point. I obviously could be wrong though.

[flyingmonkey35]

This where I got me load data.

IMR had it first. IMR had it befor hodgdon bought them out.

[M-Tecs]

PB was first Dupont than IMR. I didn't know Hodgdon was labeling it now. PB meant 'porous base'.

[Bullshop Junior]

I'm guessing a double charge. How do you charge your cases?

[freebullet]

An rcbs lock out die is a good investment. Never been a fan of lee products to dispense powder.

Had you checked the bore for leading prior to the kaboom? Reason i ask is I had a leading problem that would turn smooth bore in 6 shots. If a guy were to continue shooting with such a load it could eventually get ugly. The cause of that horrific leading was over crimping. You could pull a boolit and measure it.

If you go to imr website it redirect s you to hodgen

[freebullet]

Wonder if you had a squib followed by a double.

[flyingmonkey35]

I'm willing to go with overcharged. Or a weak Case. Or both the barrel is a bit dirty no worse then any other day of shooting. PC boolits is all I've shot out of this gun and have seen no leading.


I'll give urbiti a call tomorrow and see if they want it back for testing.

They have a YouTube video of them making this gun. They test all guns with a triple load before shipping.
