Go to Noslers digest and start at the safe end i found that the most accurate load they have marked worked well for me. I cant remember what it was. I used winchester large rifle primers and seat them just off the lands.
My go to 25-06 load is:
Winchester 270 Win cases, necked down to 25 caliber, then necks trimmed and turned. Just get some decent 25-06 brass preferably from the same lot.
IMR-4350 powder at 51.0gr
Winchester LR primers
Nosler 110gr AccuBond
COAL is 3.200" to start and then fine tune by adjusting seating depth but also 0.010" off lands works well.
I loaded and shot them back in 2005. They were very accurate in my Rem 700 Classic with RL22 which is my go to powder in the 25.06. I killed several deer with them and they performed well.
Just got around to shooting some loads I made up. I loaded 3 at 49grs, 3 at 50grs and 3 at 51grs,all 3 shot pretty good. I'm sure I could play with seating depth a lil bit and do better but I'm gonna call it good and hunt with it.
I'm not the greatest shot so I'm happy with this 3 shot group.
