POP - 72grs of R22 seems HOT but maybe not in yours. I and many others use 72grs behind 100's. I use 68grs behind a 110AB in my Vanguard for 3450 and submoa groups.

But as for me and my house we will serve the Lord. Joshua 24:15
I can do all things through Christ who strengthens me. Phil. 4:13

I DON'T NEED A WSM AS I HAVE A WEATHERBY!
