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

Not enough crimp? Can you post a close up of the crimp on one of the cases?
MY dies on a 38 special and .357 Magnum are setup for three crimps.
Light target........
Medium loads .............
and Factory (+P) or full hunting loads past 1200 fps.
MY lead loads get a Heavy Crimp when they go past a medium pressure loading, to prevent bullet jump.
In my 19-5 and a 158 lead I used 12.5 grs of 2400 as a full load
for less recoil and accuracy, in the old girl.

You definitely need to post a pic of your "crimp".

See what 15 gr will do

15gr performs great in my 4.62" Blackhawk.

Not so sure it is crimp alone. What size are those bullets, vs. what size is your expander plug? The heaviest crimp in the world won't hold a bullet that the case doesn't have good neck tension on. As others have said, 14 grains of 2400 may or may not be an appropriate load, but without knowing the bullet weight we can't say. I personally have taken 158s up to I believe 15 grains of 2400 for testing/chronograph purposes in my K frame, and had no issues with pull. I've settled on 13.5 grains.

My standard heavy .357 load for years was 14.0 gr or 2400 behind 158 gr. LSW. My old Lyman 45th Edition Handbook listed 15.0 gr as max. Speer #11 Reloading Manual listed 15.9 gr. as maximum. Down through the ages all these rhino roller loads have been moderated to less than 15.0 gr. I thought 14.0 gr was a plenty stout load. Accuracy was excellent. With young eyes I could get 1 in. ragged clover leaf groups over sandbags at 25 yards out of my 4 in. M-28, but the muzzle blast was brutal trying to bench shoot the beast. Never had a bullet back out, and never sticky extraction, flattened or cratered primers.

That's a good point! I've only experienced a bullet moving out of the case with a 500 S&W which was solved with a heavier crimp and even that only moved like 1-2mm.

12gr of 2400 with a 158gr bullet is all I put in a K frame. It's plenty.
I've got a 27-2 for the stouter ones.

Here's the photos. Bullets were a no-name buy from Gun Broker in a bag? Looks like missed the crimp groove, those here will know?[/QUOTE]
In the photo if the bullet is seated deeper than recommend would be more pressure. To me it looks deeper given the profile of the bullet. I like to be able to barely hang a fingernail or see a few thousands on the crimp.

Yes, that load missed the "Can"............
the bullet is seated a little too deep but you came close, only missed it by that much.

You can shoot any load you want buy how often do you tighten the side plate screws? After every outing at the range? Are the screws coming loose or is the little flex in the side plate stretching the screws?
Just wondering?
My most accurate load in my python was 140 gr Speer jhp with 2400 powder. A nice magnum load not too hot.

I use a Redding Profile Crimp die for Magnum rounds. In ancient times (1970's) we'd use a roll crimp and a taper crimp. The Profile Crimp die does sort of the same thing in a single pass.
The model 19.....
...being a lighter gun than a medium or heavy frame will be more susceptible to jumping crimp. If you fired those in a heavier frame they might not have backed out. But it looks like a little more crimp right in the cannelure would help.

Seated too deep, which is preventing the case mouth from rolling into the bullet's crimp groove.

You need a roll crimp in the crimping groove...Simple..
Some one my wife new(before we got married) gave re some reloads for self defense, 10.5 grains of 2400 for her charter arms, about the size of a J frame. I wouldn't let her shoot them didn't trust the loads of the pistol.
Got her a Ruger 9mm.
