    Releoding for the Trapdoor presents several problems.
    1. Weak action The Speer Manual Recommends keepimg the CUP below 21,000
    2. Large case. Smokeless Powders will require some sort of filler to make up for the case that was meant for 70 gr of BP
    quote:Any recommendations how to eliminate the brass damage
    Open the case mouth more, better grade of brass.

    Someone should be along with more info for you

    John,

    No, the model 1878 was not the last Springfield Trapdoor made. I know there was a model 1887.

    Yes, be sure to buy 45/70 Government in 405 gr ammo for it. It's about 14.00 to 20.00 bucks a box.

    I currently own two of them are they are a hoot to shoot. I never know if I hit anything when I take them to the range, because they shoot alot further than I can see. [:D][:D][:D]

    1888 was the last.
    I think the trapdoor was in service longer than any other service rifle
    1865 to 1888

    MOST COMMERCIAL AMMO LOADED TODAY IS OK FOR THE SPRINGFIELD (REM./WIN/ FED. 405 GN) BUT THE JACKETED BULLETS WILL WEAR THE BARREL FASTER THAT LEAD BULLETS. THE BARREL STEELS USED BACK THEN WERE NOT AS WEAR RESISTANT AS TO DAYS STEELS. AS TO YOUR RELOADING ?; YOU PROBABLY EITHER AREN'T EXPANDING OR BELLING THE CASES ENOUGHT BE FORE SEATING THE BULLETS OR YOUR TRYING TO CRIMP TO MUCH.

    You need to bell the brass a surpeising amount on this round, and then form and crimp it back up at the seating stage. I also reload for collectable (Trapdoors, Sharps) and modern 45-70 (Marlin GG, Siamese Mauser) and each presents it's own little idiosyncracies. I generally use either a 405 or a 455 gr. gascheck lead bullet in my olderguns and follow standard load values for the Trapdoor Springfield. 20 some odd grains of IMR 4198 and a light cotton ball seem to make a good load (although it looks as though it may be snowing when you touch it off!)but check your loading manuals before getting adventurous.

    With the guide gun, I use either 350 grain jacketed rounds or 455 gr gas checked lead and with the 455's, I use 37 or so grains of 4198 and a COL of "2.55 to "2.57...this is very important as the lifter will jam anything longer!
