DESTROYED MY K38 TODAY/ update #139/ range report post #148

Several years ago I had a Winchester 110gr 38spl Silvertip go off like a magnum in my 637 at the indoor range I used to shoot at. Amazingly, it was unharmed, after pounding the bulged case out of the chamber with a dowel.

All were replaced by Winchester, even the ones I'd already shot, and all were made in the U.S.A. Any factory ammo we buy is subject to an occasional flaw, no matter where it is made.
 
How would a undercharge cause the gun to blow up?

It allows the powder to spread out and burn much quicker. Think of it like this...A square bale of hay will burn fairly slowly if you light the end of it...Cut that bale in half and spread it out and light it and it will go up like a candle.

My very custom K327 Fed Mag is built on a pre-15 frame that I got cheap because someone cut the barrel off. If the frame and yoke are good, the possibilities are endless...

Have you posted pictures of this revolver? If so, can you post a link to the pictures? I'm in the process of building a .327 Federal Magnum using a M15-2 and a re-bored M53 .22 Jet barrel.

The internal ballistics of a high-pressure (50K+ PSI) bottleneck rifle round and it's relatively slow-burning propellant, are very different than that of a straight-walled pistol case with relatively fast burning powder.

You can't blow up a revolver with an undercharge of most pistol propellants, including Bullseye. These claims were investigated decades ago and were never able to be duplicated or verified by ballistic labs. The overwhelmingly likely answer was an undetected squib, and a subsequent round fired.

There are certain specific slow-burning pistol propellants - such as Win 296/H110 - that have minimum charge weights. Underloading these can cause a variety of inconsistent ignition, including pressure spikes, hangfire and squibs. The pistol propellants with minimum charges are specified by the manufacturer.

If you had a Garmin Xero, this may have been avoided.

“Seemed hotter” is not a standard unit of measure. A Garmin would have told you exactly what was going on.
If the previous bullet was lodged in the barrel, the Garmin would not have registered a shot, and maybe you would have stopped to investigate.
If the previous round was too hot, the Garmin would have told you and maybe you would have stopped. Maybe all the rounds were hot. No way of knowing.

If you don’t have a chronograph, you don’t have a clue what’s going on. I’ve seen reloading resources state velocities as much as 200 fps lower than what they chronoed.

Garmin are cheap. There’s no reason in the world for not everyone to have one.

Since they are so cheap, go ahead and buy me one. I'll PM with my address. Heck, I'll even pay the postage! :D

Wouldn't a squib followed by a subsequent round bulge and/or blow the barrel too?

Unlike this poor Model 10 that succumbed to a double charge.

I think this could be fixed with a replacement S&W barrel, (as long as the frame itself didn't warp)....

If you just want to fix it on the cheap, I have multiple K frame barrels. If you didn't care the exact model, I'd donate one to you if you want to go that route. I have several 4 inch K barrels.

Thanks, I will keep that in mind I will take to the smith next week and see what he has to say about fixing it.
 
Dang! I am in the camp of a bullet or a piece of a bullet being lodged in the barrel near the forcing cone, then subsequent bullets hammered into the barrel and basically wedged the forcing cone and it fractured. I also think that if the frame was not damaged, then it is salvageable.
 
First of all, I’m not going to buy you. What you should have said was “buy a Garmin for me”.

If you can afford 2 guns, you can afford a gun and a Garmin.

Your car has a speedometer, doesn’t it? Same concept. How many more car crashes would there be if very few cars had a speedometer.

People here are guessing whether the loaded round in question was over charged, or undercharged. If the shooter had a chronograph, he would be armed with the knowledge to answer that question. Had he been chrono graphing all that ammo that fateful day, he would have information that may have prevented that event.

What would have been cheaper? Buying a Garmin that he could still be using?

Or blowing up a $600 revolver?

Knowledge is power. Get some.
 
Not sure if owning a Garmin would have made any difference. I have one and like it a lot.

How did you shoot 60 years without a Garmin? In the dark. We all did. We really didn’t have a choice. Now we have a choice. You can choose knowledge or not.

I pulled ammo apart after I got my Garmin.
The resource I used said I should be getting 1100 fps, Nosler 185s, with the data given. I was shooting a 645. I wouldn’t have run those thru a 1911. The G3 Smiths were basically 45 Supers. Anyway, I chrono end those loads. They were going 1300+! Those loads didn’t feel hot to me. Who really knows what a 185 at 1100 is supposed to feel like?

I pulled those apart and started over, and stopped at 1100 fps.

Good luck with "the gunsmith", hoping he is the old fashioned type who is a pretty good machinist.
If not, did Steelslaver say he would fix it for you or for himself?

I have a Garmin but my pistol shooting does not admit to having it read every shot fired; although I know rifle shooters who have one clamped to their barrel so they can blame an off shot at long range on uneven velocity.
 
During the Pandemic I bought a couple of boxes of Norma .357 Magnum 158 grain FMJ. I intended to shoot it sparingly in a nice S&W Model 28-2 that I own. Reading this horror story has me paranoid about whether the stuff is safe. These rounds are made by Ruag in Hungary. Does anyone have any experience with this brand?

Regarding RUAG small arms ammunition, it is now a combine of several European ammunition manufacturers, including Norma and RWS, which is owned and controlled by Beretta. No reason to be paranoid.

This is nonsense. If I am just casually shooting, I'm not setting up a chronograph. And yes I do have one for when I actually need one.
