Picked up at a gun show a while ago some .458 250 gr lead bullets for the 45/70.... they where cheap, and I figured they could be cheap plinking rounds. my problem is, I can't find any load data for a 250 gr lead slug. I'm almost thinking these are for something else? They all measure out at 0.458, and weight is all mostly right at 250. Gr. New to the 45-70, all I've ever reloaded for was 44 mag. Any help?
Hum...250 grain semi-wadcutters lead bullets might be for a .45 Colt handgun perhaps and not a .45 2 1/8" or 45/70 as it is most commonly referred to as...
If you want to plink with that 45/70, it's a big case, so pick a powder that will fill it over half way. Try Lyman's Book of Cast Bullets. Remember, "Trap Doors" use a lighter load than the newer lever guns. For garage shooting, the "Quick Draw" .45 wax bullets and a primer are accurate and a lot of fun.
wrong size for a 45 colt,they are the correct size for 45-70. Dang,my old Lyman's doesn't have loads for that light bullet either.

I'm not a cast-bullet guy, but is it unreasonable to think these may intended to be lubed/sized to .453" for a .45 colt??
They do look like revolver bullets. That being said, Freedom Arms, the guys who make the 454 Casull, also made a 45-70 revolver at some point. I would say call Western Powders, the current distributor of Accurate powders. They would perhaps help with a load for a cast lead bullet with Accurate 5744. I shoot BPCR and have a 45-70 HiWall. Like I said, no big deal to just get 100% load density with Black Powder, put in a wad, seat the bullet, and squeeze it off. I don't know how hard these bullets are, and you definitely have to lube them before loading. Not gas checked, so keep the velocity to around 1200-1300 fps, even with smokeless powder.
