Question about reloading for Marlin 45-70

[coreyr]

Hello, I just bought a Marlin 45-70 and have a few questions about reloading. I order a few book on the topic and I'm interested in buying the Lee Classic Loader to use before I spend a lot of money reloading. The question I have which I can not figure out is which primers should I be using? The reload data I'm going to follow is:

Bullets = 300 GR. SIE HP (Sierra Pro-Hunter Bullets 45 Caliber (458 Diameter) 300 Grain Hollow Point Flat Nose)
Powder = IMR 4064 @ 59 Grs per round
What is this? -> C.O.L. = 2.525
Primers = unknown

Thank You

What is this? -> C.O.L. = 2.525
"Cartridge overall length" It indicates how far to seat the bullet. Although in this case, you will seat so you can crimp into the cannelure of the bullet.

Primers = unknown
Any large rifle primer (non-magnum)

Or you can use mag primers. I load for the 45-70 and I sometimes use mag primers. Not really needed with 4064 but I use them with BL-C2 and even 5744 which is what I use in my two 45-70's.
So do not worry about the primer. Crimp in the cannelure for your lever action. With a single shot I do not crimp.
