摘要 A projectile for cap and ball revolvers and black powder rifles including but not limited to muzzleloaders, black powder cartridges etc. A soft lead body, cylindrical in form and having a front band designed to hold the projectile firmly in place prior to firing. During it's travel in the rifled bore, it then imparts spin to the projectile improving accuracy, range, and making the projectile stable during impact with intended target. Outside diameter of band is not drastic enough to negatively affect trajectory.
