.357 mag in python

[kennedy759]

I reload .38 already, and shoot it in my python. using universal powder and 158 gr laser cast lead bullets. buddy just gave me a bunch of .357 mag brass, so I thought I would try reloading them. any problems with using lead in mag rounds? standard small pistol primers ok? looks like I can use my lee dies, just turn them out 1 3/4 turns. Lee says 4 grains of universal for a starting load, any advice?

Is this a new Python or a classic one?

I actually prefer to shoot .357 mag. cases in my revolver with lead bullets. The .38 SPL loads leave a ring in the cylinder charging holes that is somewhat hard to clean. The thing is that I have a hundred times more .38 SPL brass than I do .357, so I usually don't get to do what I prefer. To answer your question, loading those Laser Cast 158 gr. bullets and shooting them in your Python should be A ok. I'm not familiar with Universal powder so I cannot comment on the proper charge.

classic from the 1970`s

Be careful shooting a bunch of hot magnums. The classic version is not super strong and a lot of mag loads can cause issues.

It sounds like you want to load them like 38 Specials. That will work fine. A 158 gr lead bullet is the standard for that type of load.

Regarding powder and primer, stick to what your load data suggests.

The Hodgdon data matches your Lee source.....Hodgdon Reloading Data Center

Looks like Universal can cover loads from mild to fairly spicy.

standard small pistol primers ok?

For most powders and most loads, yes. Some will call for a magnum primer, but if it doesn't specify magnum primers you are good with standards.
