So what is your bp load? I am shooting the Lee 405 grain hb over 55 grains of 3F goex with about 10 grains of cream of wheat as a filler. It is all over the place off the bench at 50 yards. By contrast a load with 3031 grouped into an inch.
My bullets are not hard, so I am not sure how much of a difference that makes, especially with that load, but I don't know what else to mess with.

I'm shooting a 20:1 405 grain RN boolit lubed with SPG lube, over 65 grains of Goex 2F with a .060" thick card wad. I can't remember how much compression I'm using - I'm 8,000 miles away from my guns and gear right now.

I'd suggest buying this book by Mike Venturino: http://www.trackofthewolf.com/Catego...rtNum=BOOK-SPG It contains a lot of useful info on loading BPCR.

Here's a reasonably good Youtube video on how to load BPCR ammo. I disagree with his bullet seating procedure, but I guess it works for him: http://www.youtube.com/watch?v=DOyvtS3pOzg

emorris, Welcome to the forum!
And welcome to the 45-70.
Their are many ways to load
the 45-70.
The way I found is IMR 4198
and a card wad.
Get your self a milk carton.
Then drill out a primer pocket
of your of your shells.
Chamfer the mouth of the case
on the inside.
Cut the wax cardbord from the milk
container.
And use the case as a punch and
make some wads.
use a nail to push out the wads you made
from inside the case/punch.
After putting your load in a case,
put the card wad just inside the shell
Then load your plane base boolet and crimp.

I went through the same thing several years back. I had purchased a Wesson ANd HArrington Buffalo Classic. Which is a glorified Handi Rifle. I could find ZERO concrete information about which load level strength this thing could safely operate at. I found some folks saying that they could only handle trapdoor level loads and others saying they would hold anything you put in them. Nothing in writing and H@R/nef had no comment except factory loads were OK.

I settled on the Weak Trapdoor level loads for this rifle. Easier on the rifle as well as the shoulder.

Those 'Weak" loads have killed every deer and hog that I have shot with them.
