This will NOT buff out - 360 pd explodes

[niceguymr]

Found this over on another forum and though it belonged here too. It appears to have been caused by reloads.

According to author of original thread on other board:

"The load was 200 gr. Horn XTP'S with 27 gr. of H110.......no double charge, can't do that with 27 grs. of H111...oal of 1.600". I fired 3 rounds with no problems, checked for bullet creep, loaded 2 more rounds, fired ok............then loaded 1 round.................k'boom!"

If he blew the cylinder and the topstrap, that's an overpressure situation no doubt. I'm betting all my money on faulty reloads.

 

[MakeMineaMagnum]

Incredible. Does use of "non-factory ammunition" void the warranty?

 

[okie john]

27 grains of H110 would be a stout load for a 200 grain bullet in a 44 Magnum.

That will be an interesting call to the warranty dept.... " hello? yes, I have a small problem with my revolver..."

 

[rburg]

Its Bush's fault. Besides, the IL caused it.

DAMNNNN!

Ok, I don't even reload, and as I read the base note, I said out loud "that can't be right". If even I know that, it's pretty obvious. Someone either made a hell of a typo, or they need a guardian a lot worse than they need reloading equipment.

That's no 360PD- that's a 329 or something in a 6-shot.

360PD's are 5-shot .357's.
329's are 6-shot .44's

And yes, it's H110.
Looks like an undercharge/detonation.

I don't load H110 for the reason that detonations have been known to happen with that powder. I'm a bit scared of it to tell the truth.

I might get flamed for this- but the guy needs to suck up his pride knowing he- not S&W, screwed up his revolver.

Fact is, a normal load won't do that.
Indications are- that wasn't a normal load.

A quick review of selected pages from Sixguns by Keith shows exactly the same results on revolvers.

I do find it curious that even with space-age materials, revolvers that are over pressured in any caliber explode the same exact way as K-38's, 1917's or N-frame .44 Specials of years gone by...

Just my two cents.

 

[Vanilla Gorilla]

He's been told my many people that it's his fault. The question is whether or not he'll believe it or convince himself that a dozen experienced relaoders are wrong and he alone is correct.

 

[Andy Griffith]

Heck, I just took a look at his statement:

"I've loaded over 50,000 rounds..."

A. That's not many rounds.
B. The more rounds that you load, the more chance of making a mistake.

If you load, chances are that you will make a mistake. However, if you check, re-check, and then check again- chances are you might catch that bad load before it ruins an heirloom gun, injures pride, or creates a self-righteous idiot.

I've made mistakes in my loads- and thankfully caught them. If I ruin a gun, I'm going to suck it up and know that it was my fault. That's the calculated, yet minuscule risk that I take by reloading.

People with no personal sense of responsibility have no business reloading.

Anyone have a rough estimate of how many guns Elmer Keith blew up? I don't know if I have enough digits...

 

[tanksoldier]

A double charge may be impossible, but is a overcharge?

Could the bullet have been set back enough to raise the pressure enough to do that?

Heck, I've had a single YEAR where I've loaded and shot 50K...lol

I looked through Lymans reloading book, and could not find any data that suggests 27 grains for "ANY LOAD".

In a .357, The "MAX LOAD" with 180 gr bullet is only 14.5 gr of H110. Where did he ever come up with "27" grains.That has to be over 40,000 p.s.i. and is certainly a "DOUBLE LOAD".

I think as shooters, we need to get rthat P+ business out of our heads. "IT AIN'T NECESSARY" and can be very dangerous.

If you want to make a kill that bad, get a 50 cal. pistol.

 

[Duke426]

For a 44 Magnum, 200gr JHP the Hodgdon website shows 27.5 grains of H110 as the starting load. I don't know if you can get a double charge of H110 in that case (I don't load that caliber or powder) but he sure did something wrong.

 

[Andy Griffith]

There is only one grain of difference between the starting load and the maximum load of H110, but there is a significant increase in C.U.P.

I copied it from Hodgdon's website:

H110 .429" 1.600"

grains velocity pressure
27.5 1708 29,000 CUP
28.5 1806 37,800 CUP

That's a bit of a jump for only one grain!
There is also the precaution of never reducing loads of H110 or W296 below minimum.

These powders just don't seem as forgiving as many others out there- I think I'll stick with my old 2400 and RL-7 thank you.

 

[bagolden]

H110 is a funny powder the only trouble I've had with it involved a light bullet and possibly not enough crimp. In a Ruger BH and 250 Speer LSWC's my load was 27 gr .45 Colt caliber. (*not sure where I got that load or if it's even published in the Ruger/TC section, worked well in my gun though.) Standard disclaimer about the load though. Anyway one of the 100 bullets was 200gr NOT 250gr. The effect was a big gob of yellowish goo plugging the forcing cone and chamber throat. We found the bullet about 10 feet down range. My understanding this is what is to be avoided when not reducing H110.

About this blow up we know nothing abou this guy's reloading practices. He might well have used 20 what ever grains of Bullseye for all we know. This is the biggest reason there is only one can of powder on my bench.

On your 329 scanduim smith,I can see what elese caused it to blow,,,,,TITANIUM CYLINDER KINDA WARPED BEFORE BLOWING UP. The brand new ones [329 ngs] have a steel cylinder. But,always to be safe read the owners manual and follow to use factory loads. Not reloads on the before ng revolvers. Also do the same if smith gives you a new gun with a steel cylinder. I do not trust the scanduim frames so next time guy,buy a steel gun. leave those high priced problem child guns alone. rz625-8

 

[Spotteddog]

Amazing?
Titanium is good enough to build a bunch of an SR 71 out of, but it ISN'T tough enough for this nipple heads hand loads!
I think Mr. Burg was correct.
It's Bush's fault.....
