H110 is the Devil! & I’m so Stupid. Flame cutting my 629 5” pre-lock.

I’m so Stupid. I shoot 50 +P+ Hottt loads out my 629 5” and I destroyed it!

Did the same thing to my Colts Lawman Mk.V shooting W296 and 125gr JHP’s back in the 80’s. It still shoots, just looks kinda gnarley.

Now go try some Accurate 4100 and stay away from MAX.
ETA: 21gr isn’t a +. It’s under Winchester’s standard magnum load.

Accurate 4100… here I come. Glade I’m not the only one! Max+ load is a blast at the indoor range. Makes you feel TOUGH!

Do you know why H110 Flame cuts!

 

[wanderinwalker]

Calling it ruined might be a wee bit dramatic, aye? I'm fairly confident I put around 15,000 rounds through my 629-1 (or maybe it was a no-dash) and it saw a lot more than 50 rounds of HOT .44 Magnum ammo. Memory says one of my favorite accuracy loads was 24.0 grains of W296 under a 240 grain Hornady XTP lit off by a Winchester LP primer.

My understanding is "flame cutting" is more "bead blasting under high heat and pressure from combustion." It has something to do with the fine grain particles abrading the metal boosted by the hot gasses. On the bright side, it generally only gets so far and then increasing damage tends to taper off. Some powders are more prone to it than others. Oddly enough, I almost wonder if incomplete combustion could be as big of a contributing factor as using "hot" loads. Turning less of the fine grains of powder into gas at ignition would definitely provide more media for the cutting process.

I think I’m going to get a Used New 629 for my Super Hot Loads! check the top strap for flame cuts.

they have the Lock S&W .44 mags here used for a good price. Leave these classic S&W to .44 Special Light loads

+P+ Hottt loads

Maybe.......buy a .460....

 

[Mark_Mark]

already have one 5” (4” really but 1 “
of comp) . Will be change powder on that too. I load that super hot too. 300gn coated with 40grains of H110. It shakes the building

ooooh yeah, light .44 Special gun now! less recoil then a .357!

 

[Slamfire]

That is some flame cutting! Wow!

I am shooting up a keg of H110 in my 357 Magnums, I am not loading them so hot I get severe flame cutting.

 

[12Bravo20]

Yes everyone should stop using H110 for magnum revolver loads, they will ruin your revolvers.

Said by the guy who loads his own .410 shells that has to compete with the people using H100 for magnum revolver loads and 300 blackout.

your load is not +p+ you are below starting load I have never seen a +p+ designation for 44 magnum. I have been using W296/H110 for years with no real issues for 44 magnum I use a Hornady 180 grain XTP @ 29.5 grains of W296 with a LP primer . In 454 Casull I use a Hornady 240 grain XTP with 36.3 grains and a SRP . I also use it in 357 magnum with a SPM . I can’t imagine 50 rounds would do that but I could be wrong.

maybe my scale is set to Grams then! lol

my cylinder gap might be too tight

I Have to blame something!

 

[papajim2jordan]

Do you suppose it could be a "stainless" thing? My 4" M29-2 (blue) has seen a bit of 296 with no indication of such cutting. It does sometimes do a bit of mischief to the palm of my hand, however.

 

[edwardware]

I think that flame cutting won't look nearly so bad after you scrub the fouling off.

It's not ruined. . . it's used.

but… you guys have made my day! thought I was going to catch hell about hotter loads and distorting my gun!

sounds like everyone here has been there & done that

 

[ColtPythonElite]

That looks like built up lead spatter to me.

Hope so!

 

[GarrettJ]

Yeah, back up for a minute there. I agree at first glance that looks pretty gnarly.

As noted, 21 gr. of H110 isn't even a starting load. My Lyman 50th ed. says a 245 gr. lead gas checked bullet can be loaded from 24.0 to 25.0 gr. of H110. That should produce around 35,300 CUP. Max standard pressure for .44 Mag is reportedly 40,000 CUP or 36,000 PSI. You're not going to be anywhere close to a +P load. The only issue you will have from that is going to be potentially inconsistent ignition, maybe.

What bullets are you shooting? What type of coating? Do you have any more of them?

Go smash one in a vice. Or smack it with a hammer. What does the coating look like? Is it still sticking to the bullet, or is it flaking off?

Take a look at the second bullet from the left in the picture below. That was from a commercial bullet maker using Hi-Tec coating. They apparently hadn't figured out the application process, as I'd had failures like this from them in multiple bullet types and weights. What you want to see is like the bullet on the far left, where the coating remains completely adhered, even though the bullet has been deformed.

And here is what the failed coating will do in a new barrel. And yes, it was extremely difficult to scrub off.

I'm interested to see if the "damage" you see on the forcing cone is actually just an accumulation of failed coating material. It does appear that there has been some flame cutting of the top strap, but again this could mostly be coating.

I shoot hot loads in marline carbines.... so that doesn't happen to my revolvers...
