Perfect 45 Long Colt ammunition for any firearm that can chamber it – Governor and Judge included! Military Ballistics Industries was founded by an American machine gun enthusiast who needed an ample supply of ammunition so he could enjoy his favorite pastime. He scaled his operation to a point where he could deliver the goods to other shooting fans as well, and we’re now proud to offer MBI’s 45 Colt ammo for sale!

This cartridge’s 250 grain bullet is a round nose flat point. Its flat nose profile makes the bullet perfectly safe for a lever-action rifle, as it does not pose a risk of igniting the primer it butts up against inside a tubular magazine. The RNFP is completely enveloped by its hard polymer jacket, so hot propellant gasses will not cause toxic lead to evaporate during ignition. If you’re posting up at an indoor range, that’s going to help keep your lungs healthier. Polymer is also much less brittle than the copper alloy that’s usually used to jacket bullets, which makes this ammo safer to fire at ranges with rocky or concrete backstops.

MBI often produces remanufactured ammo, but this ammo’s noncorrosive Boxer-primed brass cases are brand new and never before fired.

Q: Would these work with my Henry 45 long colt w/octagon barrow?

Posted On: 1/28/2026 By: Ruben

A: Hi Ruben! I can't promise any kind of a performance out of a firearm that I haven't personally tested, but there's zero reason why this ammo should fail your lever gun. The bullet's safe for a tube mag.

Q: I have a 45/410 Rough & Rowdy 2.5” Derringer pistol. Will this ammo work ok In it?

Posted On: 7/18/2024 By: Chris Edwards

A: Hi Chris! Bond Arms has not tested this ammo in your pistol, although I foresee no reason why it shouldn't function as you would wish.

Q: Is the ammunition safe to shoot from a Colt 45 clone revolver? I question the use of the polymer casing in a Colt 45 revolver. I also wonder about shooting it in a Henry Big Boy rifle chambered in Colt 45.

Posted On: 10/2/2023 By: Curtis Shipman

A: Thanks for reaching out Curtis! This ammo ought to work just fine in any 45 Long Colt revolver or rifle. (To be certain, this round features a polymer-jacketed bullet – not a polymer casing.)
