I need reloading help.

[Honey Badger]

So I found some powder. Accurate TCM. It says it is/can be used in 357 magnum pistols. Ok.... that’s what I’ll be shooting it out of. However, I am going to reloading 38 spl brass. So here’s my question. I know 38 spl brass can handle pressures up to around 15,000. The 357 magnum can handle pressures around 36,000. I’ll be shooting lead, 158 gr semi wad cutter bullets with brinell hardness of around 14. I have seen 357 load data
for this powder. It says 10.3 gr will produce pressures of around 33k. So... if I cut the load down to around 3 gr. I should be able to shoot 38 spl safely and not split brass right? I’m not worried about exceeding pressures for the 357 pistol. I just don’t want split cases and incur problems like that. What say you?

Or does anyone have any info on this powder in 38 spl applications? Or even a good load recipe?

Thanks

Sleeve the inside of the 38spl brass with more brass for more resistance to the pressure.

I also don’t know what I’m talking about

I don't know anything about that powder. Some powders an extremely light charge is dangerous because it "explodes" instead of burns at a controlled rate.

 

[Honey Badger]

So I’m better off reloading 357 at the higher pressures? And higher charge?

Only if you find a good recipe for that powder in 38. They have been tested in a ballistics lab. But I would NOT try radical cutting back a powder like that. Not all powder can be used for a reduced load. Some like H110 are only recommended for near max loads. You can get into a dangerous situation like that. You can even unknowingly have a bullet not exit the barrel and lodge doing that. I think you can imagine what your next shot is going to do after that happens.
Try to find a recipe for you cal and powder or you just have to bite the bullet and find a recommended powder. Someone here may have tried this powder before and have some info for your 38 cal.

Good point above. And @Honey Badger you miss all the time so you’d never know if a bullet didn’t exit the barrel or not.

Short answer: Try to find a recipe for a load you want to reproduce from a reputable source.

It may be that you will need a different powder or bullet. You will have to be mindful of velocity with lead bullets.

you have a good point! I always figure I’ll keep pulling the trigger till it’s empty or the target is hit.

I say cut your losses with this powder and go back to your original thread requesting recommendations for 38 special powders.

If you decide to load some really hot 357 loads, that powder may be ok. You need to stay in the working range of what a powder was designed to operate at.

Stick with some proven powders with tons of load data.

Consult the Manufacturers customer service and ask them. It's likely they have the actual testing data for the loads your wanting to produce. They will also tell you if it's unsafe and why because they have tried it.
