Why do the guys on the net, and at the range, put Pyrodex down?
Pyrodex has a higher ignition temperature than black powder, some firearms dont ignite it as readily. 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.
