    Can you load black powder/pyrodex in a 45-70? Would it dick up your barrel? I just think it would look cool.

    Yes you can. Just remember bp is nasty corrosive. Be sure to clean your rifle soon as possible. I use hot soapy water to scrub out my bp rifle

    Can you use it in say a marlin guide gun? Or should you stick to the trapdoor models?

    As the name indicates, the cartridge was a .45 cal bullet over 70 grains of black powder, With the possible exception of an auto, any gun should handle BP. Please note that the case must be completely filled, no air pockets, slight compression of powder by bullet. You will need to clean the fouling out.

    it will work fine. i dont do it just cuz cleaning the gunk out is sorta a pita.

    the 45-70 is a fantastic cartridge for jut about everything and the marlins are stupid strong rifles. you cant stuff enough powder in the case t blow one up.

    local lgs here had a customer that used pistol powder instead of rifle powder and shot an entire tube of that stuff before the breach lock failed...

    i saw the rifle and it was just a sheared part where the bolt refused to stay in battery.

    low pressue black powder wont hurt it long as you dont leave airgaps in the case like C3 said.

    blakpowder and air gaps means detonation. thats a verrrrry bad thing.

    I've used black powder in several old cartridge guns. If you reload you have to remember to wash your cases in water also. Black powder worked in cartridges for about 40 years before there was smokeless. If it worked then it will work now.

    Yes, works for Pyrodex. It IS a bit cleaner than the BP. Just remember to load by volume, and NOT by weight.

    I load 45-110 Sharps with Triple 7. It is much cleaner. If you can not clean after shooting it is OK for afew days. Remember T 7 is about 15% hotter than BP. I use a wad cut from milk ctns for an Op. I would get a powder compression die and learn to use it.:) When using Pyrodex follow the same rules as you would with BP.:) I prefer to use lead bullets only with any of these loads.
