250gn 45/70 load data ?

[bigpete]

Anyone have any load data using adi powders for 250gn 45/70 bullets ? I'm getting some in amongst a bunch of reloading gear and it would be fun to see what they do. At the very least I can chuck a bunch of trailboss behind them but it would be interesting to get them boogying

I have been reading up on lever guns.Now I need one but do I get 450 Marlin .444 458 Win Mag 45/70 they all seem to go about the same

Well,it turns out the ammo is .451 instead of .458,so the question is moot.
Duncan,450 Marlin trumps 45/70 trumps 444 in factory ammo. Handliads are a different ball game. I'd still go 45/70 any day of the week coz of the history
