45/70 lever loads

So...I'm 90% sold on buying a 45/70 lever gun...

I've never loaded for a straight wall cartridge before....

What changes? If anything?

Anyone make good brass for it? Varmint rifles I shoot Lapua..the rest of my hunting rigs run Nosler brass...

Good loads start with good brass IMO..

We'll get into loads and bullets shortly...

Just wanna start figuring out what needs done load wise..if I need anything special or additional to what I already have...and what kind of brass to keep an eye out for...

Re: 45/70 lever loads

Starline makes good brass, or you can "harvest" it from factory ammo.

The biggest thing you need to think about will be a crimp. You can do that with the seater die, or buy a third die to crimp independently (which is what I do). It just makes things simpler for set up, but does add a step to your process. You need a decent crimp on the rounds, as they'll be in a tube mag, and under recoil you don't want any set-back to occur.

The Marlins seem to shoot almost any load well, so you should get it running to your liking in nearly no time at all.

Re: 45/70 lever loads

I've run into issues (buckling/kinking the case) with the roll/taper crimp in a seating die when I try to get a good hard crimp. Lee make's a 'factory crimp die' that doesn't push the bullet at all....rather it's a collet that squeezes the crimp on from the side of the case.

I generally despise Lee equipment, but that is one piece that I consider a 'must have' for loading anything straight walled that's going in a tube magazine. The cannelure is in the right place for bottle-neck stuff I load so a taper/roll crimp works out fine for those. I'd say it ends up depending on the bullet you're using. I was loading hard cast lead at varying seating depths so hitting the cannelure wasn't a given.

444 for me, not 45-70 but same applies.

You really under estimated the ramifications of the boondoggle you have just perpetrated!

Re: 45/70 lever loads

Yep, that about nails it. I'm no fan of Lee stuff, either, but I have the crimp die to accompany a set of Forster dies for my 45-70. I've done crimping with the seater, but it's just a lot less of a pain in the butt to use the Lee collet setup and just bang it out. No trial and error that way.

I've always seated my 45-70 loads to the cannelure and not fiddled with seat depth, and the gun has consistently shot 2" or better at 100 that way, so I figure I won't argue with it or mess with the process, lol.
