I have had great success with Federal 215M's with R25 and 120 gr Sierra 120 gr BTHP. I was using a reg 210 and decided to try the mag primer. I did drop the powder charge and worked back up, the 215 gained 30 fps over the 210 with everything else being the same.
Your results can vary, remember when a change in a component is made, it's always wise to drop the powder charge back and then work back up.

I have been getting great results with believe or not.....Reloder 25 and Sierra's 120 gr HPBT, shoots in the .3's
Cooper M22
Winchester Brass
Sierra 120 BTHP
57.5gr R-25
215M
OAL 3.200"
Averages 3110fps out of my 24" bbl

Alliant's max load is 58.0 grs with R25. I went to using the 215M's due to me running low on the 210M's. I did reduce my loads and worked back up and found out that I gained appx 25fps using the magnum primer over the standard.
I am really impressed with using this slow powder in the 25-06 as it's velocity is a bit more than I was able to achieve with my favorite, R-22. I would be interested in others trying something like this and see what results they get.
These are only 3 shot groups, I really cant explain the far upper right group.
