I've been reloading for handguns for a while now, but the only rifle that I reload for is my .308. I decided to try my hand at loading for the 45-70. The attached picture is of my first completed round. My rifel bore slugs a hair over .459. The bullet that I cast for this round is from a Lyman 457193 mould and drops a 412 grain bullet (Lyman #2 alloy) that measures .461 out of the mould. This round is seated a little deep. It's not the greatest picture, but I would like any comments you have, especially about the crimp. Most of my rounds will be mild-to-moderate loads, I was trying for a firm but not tight crimp. I don't have any frame of reference for the 45-70, other than pictures, so any help would be appreciated.  |

A lot depends on the type of rifle you are loading for. If a lever action, the crimp is a big issue, but with a Sharps or other single shot, not so much  |

It is a Marlin lever action.

I have never done anything different loading 45-70 rounds for my Marlin other than lube the cases than I do for any handgun round. It's a easy cartridge to load for...

I crimp them heavy like heavy magnum revolver rounds. Seen them shift around and force themselves deeper in the case on repeaters with heavy loadings. I have to seat the bullets a little deeper then normal on my gun (arisaka based bolt gun) as the throat is a little shorter and tighter then I would have liked in hindsight (was originally cut to fit the lever evolution rounds bullet profile). One of these days I'll get around to reaming it, but at the moment Im shooting 340gr cast seated just a little shorter then spec and the cast bullet allows for a descent crimp. I look to get the front edge of the case almost flush with the bullet side.

I have only reloaded it for a T/C Contender and used basic handgun reloading practices, nice tight crimp for sure.

I would tell you to crimp it tighter...fwiw you do not want that bullet moving around ...

The Marlin lever action is sensitive to overall length of the round. Just keep that in mind before you run a couple of hundred rounds to find that they won't function well through the rifle LOL.
My Marlin (with Ballard rifling and a GOOD recoil pad) shoots quite well with the Lee 340 gr cast bullet (I have the Lyman bullet mould for the Marlin (457643) but it doesn't shoot as well as the Lee (in my rifle).
The bullet mould I prefer for the lighter big game (deer) is the Lyman Gould Hollow Point bullet 457322. Cast of an appropriate alloy they work quite well and will work well in the Marlin.
FWIW

FWIW Dale53 Even if I know the the round will work, and I like it, I never load that many rounds of it. Loads are like girlfriends; you think "this ones really the one I love, she's for me". Until something else comes along.LOL |
