I went to search, I've never been able to get the search to tell me anything.
Anywayyyy, I shoot a lot of .45/70, have four rifles, one of them a trapdoor. That's the issue. First question is, does anyone out there have a safe smokeless load for a really tight model 84 trapdoor? I have loads for the Summit, and the Marlin, and my Remington rolling block seems to digest them without any problems, so far. If I had a good soft load for the trapdoor, I'd use it in the trapdoor and the rolling block and then wouldn't worry about damaging my antiques. Also, does anyone know where I can get nickle plated .45/70 brass to make it easier to keep the low power loads seperated from the rest of my .45/70 loads? I may be in the wrong forum here, but I don't know where else to go. Thanks, Mike Marlin model'95 .45/70 Remington #1 business rifle .45/70 Model 1884 Springfield trapdoor sporter, 26" barrel, English sporter stock, built many years ago Gibbs rifle co. "Summit" .45/70 bolt action |

From Lyman's Cast Bullet Handbook - 3rd edition
Loads greater than 15,000 CUP should be used only in Springfields (the so-called trapdoor Springfield) in good condition and should not exceed 17,000 CUP What grain bullet are you wanting to shoot? Here are the loads that DO NOT use a dacron filler Mold #457191 - 293gr - SR-4759 start 26.0gr 1311fps 9,400CUP, max 30.0gr 1602fps 14,600CUP Mold #457193 - 420gr - IMR-3031, start 34.0gr, 1161fps, 11,100CUP, max 38.5gr, 1352fps, 16,000CUP All the other loads are using a 5/8" square x 1/4" thick Dacron wad over the powder. Other bullet weights listed ar 322gr & 366gr. They also have loads for 1886 Winchester and 1895 Marlin, no other particular warnings on it and the loads vary from 9,600CUP to 28,300CUP Ruger #1 & #3 loads go up to 40,000CUP So, anything else in particular you'd like me to type? |

Thanks, dad. I've used a similar 3031 load for some time, 30 gr., in the rolling block, but I was afraid it was too much pressure for the trapdoor. I like that load. It's clean, and stiff enough to befit this fine old cartridge. I've been using a piece of paper wadding against the powder to assure it stays against the primer. That's good to know. I can quit worrying about stretching out my old rifles. I have some real snorters for my modern rifles. Thanks, Mike |

Duhh! My uncle and I always used a sharpie to designate what loads were in our brass. Do you guys have some idea more permanent? Thanks, Mike |

Thanks, Mike I use a fine sharpie on the primers to put a number or shape (square, triangle, circle) that is in my reloading log. When you punch out the primer to reload it is gone. |

Less chance of the marks being rubbed off by mistake. Black primers= Trapdoor ! Thanks, Mike |

Passing along internet lore, i.e., I've never tried it, but it sounds like a good idea. Brass Black Anyway, I've heard to put your cases in this stuff to turn the case head black - and it won't rub off. They're even saying as much on their website.

Thanks for the ideas. My uncle was an avid reloader. I usually reload simply because I can't find ammo for some anachronistic firearm I've bought. I'll find a load for say, .30/40 Krag, that doesn't show any pressure signs and stick with it. Friends accuse me of dropping out of Hi-Power competition because I hated to reload.
I have some of the brass black, and used it on the brass of a generic Hawken B/P rifle. It didn't make the brass black, what it did do however, was make the brass look like some of the prettiest color case hardened steel I've ever seen. I have some brass that will be tossed. I'll clean it, and try the brass black. I'll get back to you on this. Thanks, Mike |
I use 49.0grns of Varget under a 415grn cast bullet. The pressure is accepable(right at 19,000 lbs in my 1884 Trapdoor)and they are running right at 1600fps. This load seems to work good all the way out to 900 yards. We have a full size buffalo silouette on our range and it's at 900 yards. The information that I have concerning cup pressure is that a Springfield Trapdoor in sound conditin will handle 25,000 lbs.

I bought my trapdoor at the Denver antique gun show several years ago, and if it was shot at all before I got it, not much.
The guy I got it from sold it to me for $175 because someone had sporterized it and he considered it ruined. Ruined or not, it's still a lot of fun to shoot. I've shot black, and pyrodex in it, but it's a bitch to get really clean, and I saw a guy at one of the local ranges shoot his with smokeless, but I didn't get a chance to hit him up about loads. Thanks, Mike |

My "ruined" Trapdoor, Model 1884, 26" barrel, I'm guessing Remington 700 sights,!?! but it all seems to work, and is a ball to shoot.
And, before you guys gripe, check out page 23 of Jack Behn's book, '45-70' Rifles. Look at the third type Officer's Model 1875. Mike
