Abstract: Electronic ignition systems which are designed for use with personal firearms utilizing black powder (or black powder substitutes) such as shotguns, rifles, and pistols. Generally, the firearms will be of the type classified as muzzleloaders. The electronic ignition systems generate an electric arc in the barrel of the firearm which ignites the propellant charge in the firearm discharging it when a firing switch is closed.

Abstract: An electronic ignition system for use with a personal firearm utilizing black powder or black powder substitutes, such as a shotgun, rifle, or pistol, is disclosed. The electronic ignition system generates an electric arc in the barrel of the firearm, which ignites the propellant charge in the firearm, discharging it when a firing switch is closed. A sequential discharge of lower and higher capacitance capacitors increases reliability of discharge of the firearm. A multi-switch system may include an arming switch to charge the ignition system, a safety switch to selectively enable and disable firing, and/or a firing switch for triggering discharge of the firearm, for increased safety in use.

Abstract: A portable, elevating stand is constructed of a platform movably connected to a generally columnar upright support having a height along which movement of the platform is constrained. Connection between the platform and upright support may be through a linkage assembly comprising channels in which are positioned flange portions of the upright support, such flange portions being located along a majority of the height of the upright support. The platform assembly may be driven by a portable electric motor, including the use therefor of an hand-held electric drill, which is carried onto the platform assembly prior to use of the elevating stand. A method of raising and lowering a portable, elevating stand includes carrying onto the platform assembly a portable motor, engaging the motor with a means for raising or lowering the platform assembly, and operating the motor to effect raising or lowering of the platform assembly.

Abstract: Projectiles for firearms, specifically bullets, are discussed that include a rear thin-walled counter bore. The counter bore is designed to be a first size and shape when the bullet is loaded into the firearm and expand upon discharge of the firearm so as to force the walls of the counter bore into barrel rifling. The expansion may occur through the direct interaction of propellant gases with the counter bore walls, or at least partially indirectly though the inclusion of an expansion plug that is placed at least partially within the counter bore in a manner that the expansion plug can be driven further into the counter bore by the firing action of the firearm.
