All Loads used CCI 200 Primers and Hornady 150 gr Intelock Spire Flatbase loaded to 3.220". Velocities are from a 22" Ruger M77 MK II. Obviously some of these aren't reduced level loads, but you can see what ranges the powders worked over.
For what you are trying to do and using Reloder 7, I would try things around the 32-36 gr charge level and see what your rifle will do.

I found 34.8 grains of RL 7 with a Hornaday 150 to be perfect. Low recoil, sub MOA, pleasant to shoot. I used the odd charge weight only because that's what my measure threw.
Thank you.
