I always thought it would be neat to use black powder in an "old" lever actioned rifle on a deer hunt. Any particular problems that would prevent me using a 94 winchester or even a marlin 336 with black powder for the occasional hunt and would it be better to use cast bullets as opposed to regular jacketed bullets with the lower velocity I would expect?
Lots of experience reloading, none at all with black powder, or the cartridges mentioned for that matter!
Those cartridges can be loaded with bp, the result may be less than stellar. I have not loaded the 32 special, but the difference between it and the 32-40 are very slight, and the 32-40 is known historically as one of the more accurate match shooting cartridges.
The 35 remington I load with smokeless and haven't ever had the urge to shoot it with black.
The 30-30 will benefit greatly by adding one of the lubed felt wads for a 31cal cap and ball revolver on top of the powder.
I would suggest if you try any of those 3 to use 3f blackpowder, fill the case to just short of the mouth and then use a Lyman "M" die to compress the wad and powder to just short of the base of the neck. Don't use any more crimp on the bullet than it takes to take the flare out of the case mouth.
Cleaning up after firing blackpowder is not as hard as those on the internet that haven't done it, always seem prone to make it out to be.
Start by opening the action and pointing the ejection port down So when you push the patches down the barrel they fall to the floor/ground). Then blow a few deep moist breaths down the barrel. Then push a dry patch down the bore with a jag on the end of your cleaning rod. Follow that with a damp patch (just water works fine) followed by a couple of dry patches, and repeat until the patches come out clean. At this point you may need to use your favored lead mining technigue if your patches show grey streaks or splotches.
Liberal coat the bore and the inside of the action with your favored bore cleaner. put the gun up until the next outing, don't forget to wipe the oil out of the bore before shooting.
cleaning the cases, deprime the cases, drop into a coffee can with about 1/4 inch of simple green in the bottom, when all the cases are deprimed and in the can fill with water until all the cases are covered. Shake the can for a little bit. Then flush with cold water until the water comes out of the can clear. Spread cases with mouths down to dry, when dry put them into the tumbler and make them sparkly again. If you're not going out in public and don't care if you have grubby looking cases skip the tumbler part.
