I just picked up an 1873 trapdoor springfield(1878 manufacture date based on serial number) and was wondering what if any factory 45-70 loads are safe to fire in it?

I have had no problem with any "cowboy action" type Winchester factory rounds in my trapdoor.

I'll tell you though, I have reloaded everything in Blackpowder for the 45.70 and it's a blast.

I also understand that the jacketed hp's are bad for the Springfield barrel.

Go check out Greybeardoutdoors.com.
They have a lot of info on the 45-70 ammunition and what type can be used in the older springfield rifles.

My LGS has a trapdoor (same place I just picked up the 1917 Enfield). Doesnt have a price tag on it and its kinda rough, and my money is all gone, but I want one bad. I'm jealous

I got a 1884 Trapdoor for Christmas, still haven't shot it. But, I finally got dies and some brass and bullets, so I loaded up some test ammo. I loaded a 405 grain cast bullet from Missouri Bullet Company over 5 rounds each using 43.5, 45, and 47.5gr by weight of Shockey's Gold FFG powder. I know the BP load was 70 grains, but I just didn't see how I could fit 70 grains (by volume) of that powder in that cartridge and get the bullet in any meanigful distance. I know you're supposed to compress the powder but, damn, that would be a lot of compression!

Hopefully one day soon I'll get to go try them.

Remington makes safe for trapdoor .45-70. Make sure the box says safe to use in trapdoors on any store bought ammo.

Also, you can shoot jacketed bullets in aTD I`v been shooting them in my 1873 & must have a least 700 rounds down the barrel & it still will put 5 in 6" bull at 100 yds. I do reload & use smokeless powder. Remember, the copper is much softer then that steel barrel, & no they won`t wear the rifling out either. Win. ammo is also safe to shoot in the old TD
