40-70 SS loads

Mike.

I haven't shot my .40-70 for several years but I used to load it with a 420 gr GG or a 400 PP using 72 gr of the old 2F goex exp powder that had a 1/16 ROT barrel.
I haven't loaded and of the O-E powder yet in the .40's but I'm finding the 3F O-E powder is shooting quite well in my .45-2.4 and the .44's I been working with lately. It is a very fast powder, cant tell you just what the velocity is but judging by the dust kicking up down range it is mighty fast.
The 3F O-E is showing a pattern of low to no compression so far from the results I been getting. Between .100" and .150" has been proving out well.
