Shotshell shooters can use muzzleloading shotguns, or use black powder shells. Metallic cartridge shooters have an array of cartridges available, including some old-time black powder cartridges which survive today in smokeless form, such as the 30-30 and the 45/70. However, there are a number of black powder only cartridges in use, too, such as the 50-100 and the 38-55.
Not every store that sells firearms and smokeless propellants carry black powder, due to its explosive properties. But there are black powder substitutes. These substitutes go by the trade names Pyrodex and Black Canyon.
Pyrodex is volumetrically equivalent to black powder. Do not measure Pyrodex by weight.
Black powder can be ignited by impact or static electricity. It can cause an explosion when ignited, even when not tightly enclosed. It must be transported and stored as an explosive. Pyrodex is somewhat safer, and can legally be transported and stored in similar fashion to modern smokeless propellants.
A store which sells Pyrodex has far less trouble with regulators, insurance companies, and shipping firms than one which sells black powder. Therefore, it is more readily available.
Should misfires occur when your firearm has been cleaned, prepped, and loaded properly, and you only have Pyrodex available, contact your firearm manufacturer. They may have optional equipment available that could improve reliability.
Some manufacturers offer special percussion nipples for using Pyrodex, others have special ignition systems which use centerfire primers rather than percussion caps.
There have also been concerns about shot-to-shot variability. Hodgdson now markets a premium product called Pyrodex RS Select, which uses more consistant grain sizes than their standard FFg compatible product, Pyrodex RS.
Reports in rec.guns describe the product as producing less smoke, no sulfur stink, and much less powder fouling. Reports also mention requiring a compressed load in order to function with consistent velocities and without misfires. At this time (January ‘96), I understand it is only available in one grade.
Corrosive powders leave various complex salt compounds in the barrel and action. Just like road salt on a car, these salts attract moisture, and the moisture will cause corrosion. And just like a car, one wants to remove the salts as soon as possible to minimize the rusting.
Hot water and liquid dish soap will dissolve the salts. You can also use a black powder solvent.
The general consensus seems to be that soap and water is recommended when plumbing is available, and black powder solvents at other times.
The percussion caps I have seen for sale have been non-corrosive. To me, this means that if you use non- corrosive caps, you can fire a few to burn away oil or grease from your nipple and flash hole after taking your unloaded firearm from storage; then load with black powder and not need to clean the firearm until it is fired.
Once again, black powder is more dangerous than smokeless powder. Never smoke around it, don’t store percussion caps with it, and keep it separately from your smokeless powders, so you’ll never confuse them.
Black powder firearms are just as deadly as “modern” ones. All standard firearm safety rules apply. Some extra rules apply to muzzleloaders and percussion revolvers. Of course, you should now how to confirm your firearm is unloaded, and you should know its safety systems, if it has any.
