Box of Twenty blackpowder .45-55-405 Government (Gov’t) Carbine cartridges.  New production ammunition!

17 in stock


Box of twenty new production black powder .45-55 Government Carbine ammunition.  Round nose, hollow-base 405gr bullet to replicate the original 1886 load for the Trapdoor Springfield line of carbines.

In 1886, the US Army adjusted their ammunition in order to distinguish the 45-70 rifle ammo (500gr)  from the 45-55 carbine ammo (405gr).  Before then, they sat the projectiles to the same overall length, which meant the only way to tell them apart was by the paper packaging (not a very effective method of keeping them straight).

We can do custom loads as well.  Please contact us for a quote.


Before firing:

– Confirm you have the correct caliber

– Have a qualified gunsmith inspection the condition of your firearm

– Always wear eye AND ear protection

We assume no liability for the proper function of your vintage firearm.

    Just wanted to say service was great and all questions were answered. I have not shot the ammo yet but couldn’t be happier with the communication with Old South Ammo!
