Speed green or Blue angel?

[quietmike]

Just got a new (to me) 45/70 guide gun and have an accurate mold on the way.
Been casting for a while, but never for 45/70.

I know there probably are better choices out there, but I already have quite a bit of speed green and blue angel, so I'm wondering which would be better?

The bullets I'll be using are gas checked 350 and 430 grain and a plain base 525.
They'll likely be midrange loads.

Since I have very good luck with speed green it would be my choice. I have a 1895 Marlin CB and use a very old 456192 sized to 460 (Buckshot) going 1200 fps.

I too have excellent results from speed green. Since you have it already, why not work with it and get back to us and tell us how you did?
