I'll be interested in your results. I've pulled an old S&W M1500 7mm RM out of the closet and figure on maybe working up some loads for it. I was going to try 150 E-Tips, 160 AB's and 180 Bergers and/or JLKs. I'm going to try Retumo and H1000.
Do you shoot at the Logan range? If so, it would be a pleasure to get together and shoot some, sometime.
Cheers,
MR
