Ammo Inc 45 Colt 250 grain JHP ammunition puts 385 ft-lbs of energy downrange at 842 fps, balancing expansion and penetration for self-defense scenarios in classic wheelguns and modern lever-action rifles. The 45 Colt (Long Colt) cartridge, adopted in 1873 for the Colt Single Action Army, remains a go-to for handgun hunters and CCW revolver carriers who need a load that opens reliably without fragmenting. This jacketed hollow point uses a copper jacket over a lead core, with a cavity engineered to initiate expansion on impact while retaining enough mass to reach vital zones. Boxer-primed brass cases seat consistently and eject cleanly, and the non-corrosive primer keeps your cylinder and barrel fouling-free between cleanings.
Built for the Box
Each 20-round box ships from Ammo Inc’s Arizona facility with lot-consistent powder charges and crimps uniform enough to pass quality-control pressure testing. The brass case headstamps with boxer primer pockets, making spent cases reloadable for handloaders who want to tailor velocity or swap projectiles. Lead-core construction meets traditional accuracy standards without the premium price of bonded or monolithic bullets, and the 250-grain weight stabilizes in barrels as short as 3 inches or as long as 7.5 inches. You’ll find this load indexed under “Self Defense” in the Ammo Inc catalog, signaling a powder burn rate and bullet design tuned for two-legged threats rather than paper or steel. The jacketed hollow point expands predictably in FBI-protocol gelatin at velocities above 800 fps, and the 842 fps muzzle velocity from a test barrel gives you margin even after real-world barrel losses.
