What blew up my gun?

I had a room mate years ago that went to work for a gun manufacture in Utah. They built 45 win mag. pistols. They would put the equivalent of 5 times the max load, and put a solid barrel instead of a bored out barrel and fire it to see if the frame would hold up. It did some damage but the frame held.
LH.. Was that the Wildey pistol you are speaking of? The one Charles Bronson used in one of his ''Death Wish'' movies??
 
I'm amazed that they were able to get 5 times the normal amount of powder in the cartridge.

He said the equivalent of 5 times the max load. A .357 mag with a 125 grain JHP bullet can tolerate about 20 grains of WW 296 easily. 20 grains of Bullseye might not be so tolerable. it was often said that double charges of Bullseye would demolish most revolvers.
 
I just this morning thought of this....is it possible that the brass was too long, actually entering into the throat area and not allowing the bullet to release easily/properly! memtb

That's what I was thinking as well. I load 35g Varget with 55g bullets in my .22-250 and it's not a max load.

Question for the OP - do you trim your cases? If so, how far back do you trim them and is it possible you missed one?

It's always possible I missed one.

I pulled all remaining reloads from this batch (approx. 20)
Powder looked like powder in 1lb bottle (not powdered or anything)
Case length were all between 1.88" & 1.91" ( in spec.)
All cases had 34.6gn of Varget except 5had 35gn, 3 had 36gn & 1 had 37gn
I went back to Hornady Load Book and 34.6gn is absolute Max for 55Gn V-Max bullet
The loads I've been making are for 50Gn V-Max bullet. (which I used previously)
Max amount of Varget I could get in a 22-250 case is 39gn
 
I had a friend put a 270 Winchester round in his 270WSM Ruger M77 and when it went off it destroyed the action. Noone hurt...

I know how I reload and the steps that I go thru to do it. They don't vary too much. I personally don't believe that over charged chases were the problem. I think that cleaning media could have been stuck in the case to cause the case to fail from over pressure. Just my 2 cents worth.
 
270 win is .284 longer at the shoulder than 270 wsm, the wsm is almost .100 bigger in diameter at the shoulder so it wouldnt even start to chamber
 
All we can really do is speculate . reassembly and testing so as to reenact , without the explosion , the event are probably the best way to get the best answer . I've seen this done with large high speed fans . They do it with aircraft as well as other things .

Just a couple of possibles. Since your powder wts aren't consistent, were you loading with a powder measure instead of scale? If so, it is possible you had a "bridge" on one load that then broke free and overcharged the next load. OR, and I have seen this a few times over the decades, a heavier wt bullet found its way into your box of 55's. These mistakes can come from the factory or a lose bullet was mistakenly placed into the wrong box. I.e. a 60gr Hornady placed into a 55gr box. Just last year, I found a 147gr 9mm in a factory box of 124gr Gold Dot bullets. In past, I have found 180gr in a 165gr 30 cal. box, a 158gr in a 125gr XTP box, etc.
