Guys, I have an original 50-70 Trapdoor Springfield in excellent mechanical condition that I have owned for many years. It appears that the state of Indiana will be approving the 50-70 cartridge for deer hunting this fall season and I'd like to be prepared with a new load for the old gun. Anyone out there have a load for 440 Gr. solid lead bullets that will be in the range of 1200 FPS MV? I have no interest in shooting anything but smokeless powder. Thanks for any help, BOBinIN

Might not be a good idea. Quote from: www.riflemagazine.com/magazine/article.cfm?tocid=220&magid=18 "It should be stressed that under no circumstances do I recommend using smokeless powder for reloading .50-70 Government loads to be fired in 1870’s vintage rifles - especially “trapdoor” Springfields. However, for modern manufactured ones such as this Lone Star rolling block or Sharps produced by either Shiloh or C. Sharps, there is no problem in using smokeless powders if the loads are based on suitable data." |

Are there any other cartridges that you have heard about. Recently I heard that the additional cartridges under consideration had been tabled but crossbows were still being considered during archery. By the way, I have an original 1873 trapdoor in 45-70 That I shoot smokeless trapdoor loads in with no problem. Orange County.

I found one 50-70 govt load at www.handloads.org It said that it duplicates pressures of black powder, check it out. |

Hit the cast boolit forum. They have a huge amount of info on the older cartridges. You may even want to go smokey. castboolits.gunloads.com/10 ga |

TrailBoss lanenebraska, That's kind of general...can you be a bit more specific as to an actual amount for a decent load that you recommend? |

Bob
I would treat that gun like a 45-70 trapdoor to start, and check out these loads listed by Hodgdon:
data.hodgdon.com/cartridge_load.asp
I would start with about 10g TB, under a 400-500g Cast Lead bullet. Or the lightest cast bullet you have. Then check for pressure signs, and move up slowly.
My experiance has been, that when using TB in most large cart cases=44-50cal, will give you just about HALF the speed of regular designed Blackpowder loads.
And it fills up the case better than any other "reduced load " powder on the market. Plus it burns very clean too.
