(5 customer reviews)


Set of three 45-70-500 Government M1886 dummy rounds / snap caps / fake bullets.

Cartridge Options Explained

With this option steel BB’s (ball bearings) are added to the cartridges. This makes them rattle when shaken, aiding in identification as inert, snap caps.

Cartridges all patina darkened to aid in identification.


Set of three .45-70-500 Government dummy rounds / snap-caps / fake bullets. The 45-70 was adopted by the US Army in the early 1870’s and was used in the Army’s “Trap door” Springfield (M1873, M1888).  This version of the cartridge utilized a 500 grain bullet set to 2.795″ in order to differentiate it from the 45-55-405 used in the carbine version of the “Trapdoor”. It was the US Army’s standard 45-70 from 1886 until is was replaced by the 30-40 Krag.  It was also very popular with civilians, especially in the West when buffalo hunting was prevalent.
Available with spent primers remaining, empty primer pockets, holes drilled in the cases, or rubber inserts added to the primer pockets.
Great addition to your western or Spanish-American War re-enactment kit or display with your fine piece of American history.
Thanks for looking!

    Just what I needed

  3. Ron W. (verified owner)

    45-70 bullets are a little too large diameter to extract from an original trapdoor carbine. Sandpaper fixes it.

  4. Alan S Kenney (verified owner)

    Looks great in my display case without keeping live ammo next to my rifle

    Don’t think reproduction snap caps get any more accurate than what J&M can produce.
