25 Sherman LA. Load data help?

[Michael Hirschi]

I had an incredible friend build a 25 Sherman LA rifle for me. I am trying to build accurate and safe loads using IMR 7828 SSC, H4350, and Reloader 26 powders. I'm using bullets ranging from 100 gr to 135 gr. Anyone have some great recipes for this rifle? Thanks for your help. God Bless America .

What brass are you using?

Tell us about your build ! Barrel length?
It's a fantastic cartridge from what I've seen of mine, getting on the heels of 257wby using a lot less powder.
