What 14 gains of 2400 did in my M-19-4

[Jersey Doug]

Looks like I have a lot of re-crimping to do?

Yup, pretty stout load in a K frame 357.

I typically only load 19 grains for my blasting loads in my .44 magnum Mountain Gun.

 

[Mike SC Hunter]

My standard load for 357 is 13.5 grs of #2400 and a 168 gr cast bullet. I don't shoot these lads in my 19. In 1986 I busted the forcing cone on my 4"19 with 150 gr cast bullets. Pics of it are posted on older threads.

 

[Jersey Doug]

Agreed, this batch going through my M-28 only.

Yes, 14 grs of 2400 in a 357 is definitely not a starting load. Especially in a K frame. I doubt if you can even work up to that amount without excessive pressure. What a shame.

Lee Factory Crimp Die works wonders for heavy magnum loads.

The pics are much better than what I was afraid we were going to see!

I have some 14.0gr 2400 loads behind a 155gr WFN I cast out of some pretty hard alloy. I haven't shot them yet but the 13.5gr loads didn't seem too crazy.

My hunting load in my pre 27 is 13 grains
of 2400 with a 173 gr. Keith bullet and consider it a heavy load.

For yrs I shot a 180 gr cast bullet on top of a full charge of W296 ( current load data ) in a 4" K frame , model 19 357 , never a problem . The gun is still as tight as it was the day I bought it . regards Paul

14gr of 2400 pushing what bullet?
That charge behind a 110gr JHP is a lot different than the same charge behind a 158gr LSWC.

We could assume but you know what happens...

Without even knowing what weight bullet the op's loaded, since he didn't tell us, how can we know that?

You did not mention grain weight of bullet but I would guess either 180 or 158 grain by your picture. For 158 grain it would be close to maximum load and would require a nice crimp.

I purchased some Buffalo Bore 180 grain 357 magnum hard cast LSWCFP for walking in he woods in Black Bear country. The crimp on those is crazy - but the proof of the pudding is they don't jump crimp.

I download my 158 grain .357 rounds to 12.8 grains of 2400 for my 19's and 66's. I hope that's low enough to avoid any problems.

 

[kenjen]

with a 158gr. bullet and 2400 powder, I use 11-12 gr for fun loads and 13-13.5grs for hunting. I do use 14grs but save them for my Marlin rifle.

 

[rockquarry]

I don't load any magnum handgun cartridges anymore, but when I did, I found best accuracy with 12 grs. #2400 and a 160 grain cast H&G SWC. Not an unpleasant load to shoot and I think muzzle velocity was around 1100 fps, maybe a little more. 14 grains of 296 /H110 was comparable in accuracy and velocity, but with that horrendous fireball and significant blast that such powder was known for.

So glad you only have to deal with bullets jumping crimp!!! Saw the title and thought you'd had a gun let go on you. Sincerely. bruce.

SPEER #9

Used as reference for the load was Speer reloading manual Number Nine. There's 158gr. (like I used) loads that go beyond 14 to 14.7 and 140gr. at 16.5 of 2400 ?

In my heavy M-28 the 14 grains seemed equivalent to factory .357 bullets and used that load for years. This K-Frame 19,, had just switched it's 8-3/8" (modified) barrel to 4".. "agreed" too hot for my intended use.

You should see the crimp BB puts on their 340gr 44mag ammo!!!
If it was not so perfectly done a guy might think they were using a vice.

So it made your camera not able to focus?

Taper?

Back in the '70's bought this extra Taper die for this purpose. Will have to go over the 500 shells made using it. Thanks for the info.
