proper ammo

Bought an original Springfield 45/70 trapdoor and an orginal Springfield 30/40 Krag from a buddy. Would like to know the proper ammo to fire through each.


Both ammos are available, BUT I don't want to exceed pressures for antique rifles. Both bores on the rifles are dark, but both are fireable.

Serial number on 45/70 51110
Serial number on Krag 411831

    In the Trapdoor I?d only shoot Cowboy style ammo like from Black Hills or learn to reload and use black powder. I definitely wouldn?t run high octane stuff like Buffalo Bore or Garret unless you want a grenade. The Krag you should be able to run factory ammo like Remington and Winchester make.

    I think any Factory ammo would be fine in the 30-40. The SAMMI specs for it are established and have been based on the original loading.

    For the 45-70 shoot, like stated above the "Cowboy" loads would be fine.

    Remington makes a load "For all Rifles" with a 405gr SP.

    Where it gets fun is when you reload for the trapdoor. Trailboss and A5744 powders are great for low pressure loads.


    One trick I use when loading 45-70. I have several Marlin 1895's in 45-70 that will handle "hot" loads. When I reload for the trapdoor I used nickle plated brass so I don't get them mixed up. The regular brass cases are for "Modern" guns only.
