High velocity ignition system for ammunition
First Claim
1. A shotgun shell comprising:
- a shotgun shell casing having a base portion and a forward portion configured for a shotgun;
a primer provided in the base portion;
a payload being one of a plurality of shotgun shell shot pellets and a shotgun shell slug provided in the forward portion;
separation structure provided rearward of the payload, the separation structure defininga first propellant region located in the casing intermediate the primer and the payload; and
a second propellant region located in the casing intermediate the first propellant region and the base portion;
the separation structure having;
a flash tube substantially extending between the primer and the first propellant region;
a divider separating the first propellant region from the second propellant region, at least one channel extending between the first propellant region and the second propellant region;
the shotgun shell further comprising propellant in the first propellant region and propellant in the second propellant region.

Abstract
A high velocity ignition system for ammunition including an casing, a primer, a payload, a first propellant region, a flash tube, a second propellant and at least one channel. The casing has a base portion and a forward portion. The primer is provided in the base portion. The payload is provided proximate the forward portion. The first propellant region is located in the casing intermediate the primer and the payload. The flash tube substantially extends between the primer and the first propellant region. The second propellant region is located in the casing intermediate the first propellant region and the base portion. The at least one channel extends between the first propellant region and the second propellant region. A separator with a forward extending cup and a rearward extending cup has a cylindrical portion that engages the inside surface of the casing, spans the internal distance in the casing, and defines flash pathways between the primer and main propellant and between the main propellant and the secondary propellant.

7. A method of increasing velocity of ammunition without increasing a maximum pressure rating for a gun system in which the ammunition is used, the method comprising:
-
activating a primer to cause a first flame to be emitted therefrom; directing the first flame through a flash tube towards a first propellant region and past a second propellant region, the second propellant region position laterally of the flashtube and rearward of the first propellant region; igniting the first propellant region with the first flame; directing a second flame from the first propellant region to the second propellant region through at least one channel, wherein the second propellant region is in a spaced-apart configuration from the first propellant region; igniting the second propellant region with the second flame; and propelling the payload away from the casing with a combined force generated by the ignition of the first propellant region and the second propellant region. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
