Reloading. What would happen if i reloaded my centerfire cartriges with black powder?

I want to reload some shells to scare people at the range when a huge puff of smoke comes out.Reloading. What would happen if i reloaded my centerfire cartriges with black powder?
Many of the older shells were actually designed to be reloaded with black powder. For example, a 45/70 got it's name because it was a 45 cal loaded with 70 grains of black powder. Guess where a 30/30 and a 44/40 got their names. Beware that black powder is corrosive, so your guns must be cleaned properly after shooting. If you can find the appropriate load information for the caliber you are shooting, have at 'er. I wouldn't go it blind. You need to find the correct info before you proceed. What caliber were you wanting to load. Let me know and I'll help you look for a load. It's snowing again outside and I got nothing better to do.Reloading.

Unless you are shooting a old black powder cartridge that survived the transition to smokeless like the 45-70 you would very quickly foul the bore and have a devil of a time cleaning it. The rifling twists are a lot quicker for small bore (comparatively) smokeless rounds. It would be safe but I doubt it will be worth the effort to clean especially as you have to clean up after black powder with a black powder solvent or soapy water and then dry and oil everything.
Your reasons are very childish. The gun range is no place for pranks. You should save the childish pranks for something other than your guns and the gun range.





Now, if you want to load your cartridges with black powder, you won't hurt a thing as long as you know how much powder to put in the cartridges. You will have a pretty serious cleaning job ahead of you after shooting the black powder cartridges. The combustion products of black powder are very corrosive and have to be completely cleaned from your firearm or it will corrode. The best way to remove all of the corrosive products of black powder combustion is to thoroughly wash your gun barrel in hot soapy water, rinse it with boiling water and spray with WD-40. Wipe away all of the excess WD-40 and apply a coating of a good gun oil.





But, please, no silly childish pranks at the gun range. When handling and shooting guns, be serious and be safe. If you're not ready to do that, find something else to do and leave the guns alone until you can be serious and safe.
You could be more specific with your question. Many of today's popular cartridges began life as black powder cartridges, though they now have smokeless loadings. And then there are some like 32 Winchester Special that, though originally in smokeless loading, was designed to be reloaded with black if the owner wanted. Others simply have no known safe loading.


I can personally attest that if you shoot black powder loads in a 45 Colt revolver, you're likely to raise no eyebrows at all, much less cause a fuss.


I've also shot a double rifle in 500-3'; BPE at the range, and all I got out of that was one of the range officers told me I should rest the barrels on the sandbags instead of putting my elbow on the bags (doing as he suggested is proper for single barrels but dead wrong for side-by-sides).
A lot of smoke and fouling and a loud bang, but nothing much more.





The smokeless powder in a cartridge is far more powerful than black powder could ever be.





I reload shotgun shells with black powder for old, antique shotguns here at home. They're so low power that it's not even close to smokeless.





Just be sure to fill the entire space in the cartridge. Use Cream of Wheat as a space filler. It's not going to cause any real probs if you don't, there's just not enough space in a cartridge, but do anyway. It's a good habit.
i'm not sure the new powder we use in todays firearms is much more powerfull than black powder. now if u used todays powder in a black powder gun then it will explode for sure. i wouldnt try it non the less its probly a bad idea
what was thegrade of the powder? your are supposed to use 4x gun powder for reloadind cartridges.black powder is for mussel loading firearms.
With a semi-automatic, you'd probably get increased fouling, which could lead to malfunctions. Anything else, I can't even guess.
You would damage your gun. The cartridges are not meant for that type of explosive pressure, the chamber and barrel are not meant to be exploded in.
