black powder 357 magnum

Be sure you are comfortable detail stripping and cleaning every crevice of your gun.

Forget the Campro bullets and get some cast as soft as possible. Lube with a non-petroleum black powder lube like SPG or something homemade.

Dump the powder in until you get it to a level in the case where seating the bullet will compress it some but not enough to deform the bullet.

Go to the range and smoke out everyone downwind.
Clean with soap and water, oil well and repeat.

No need to use magnum primers. There is nothing easier to ignite than real BP.

I thought there was a school of thought / bro science that suggested the hotter primer makes it burn cleaner?

Same with duplex loads.


I tried BP in 45 Colt once. Never again. That thick case doesn't obturate worth a damn and all sorts of soot blows back.

I might have a go with 44-40 one day. Those cases are foil thin.

I expect .357 would be messy as well.
 
Should work out just fine, this is my 1911 on black, everything went down the barrel, the gun was clean as smokeless shot through it.
The load info is in the YouTube description.

 
thanx for all the feedback guys :)

this is more being done as one of those "maybe once in a while for shyts 'n giggles" things, I'm definitely not a huge fan of constantly cleaning the ladies lol
something where I'd make a 100-200 rounds and keep them aside for whenever

thanx too for the non-magnum primer input, tho these days the magnums seem to be a lot easier to find than regular SPs

will see how everything works out tomorrow !!!

cheers!!

That might be true of some BP substitutes, such as Pyrodex and T7, which are harder to ignite than real BP. Think about the fact that one spark ignites the BP primer charge in a flintlock's pan.

BTW, if the BP chrage is not hot enough to cause your casing to obturate, try the FFFg granulation instead of FFg. It is slightly hotter and faster burning. Always make sure that the bullet sits right against the powder.
