Dan, I bought my 25-06 in 73 as a factory gun. It had a 10 twist and would shoot 100 grain bullets around 1/2 to 3/4. Tried to go to the 120's and grouped somewhat larger. 30 years later I rebarreled with a 9 twist Shilen and changed powders. I worked up loads with 120 Hornady HP and 115 Bergers with 7828SSC. I got slightly less than 1/2moa at 200 with both bullets shooting 3 shot groups. I think the 9 twist is the better option for heavy bullets.What twist are you using or the 115gr Bergers? I am getting ready to build my first 25-06 on a older Tikka M658 with a Bartlein 10 twist?
I really like h-1000 and retumbo for 26" barrels with 115 bergers. I'm shooting 60gr of retumbo out of my sendero runnin just a touch over 3200 with the 115's.
Yes sir. Retumbo for me has been awesome. Hits deer like a one ton ford. Accuracy for me has been incredible with my factory barrel. Probably be scary with a custom barrel.Wingnut,
I shoot exactly the same load. 60g Retumbo with 115g Berger HVLDs with Fed 215M primers. I am right at 3200 fps through my 25" PacNor 3 groove barrel(10 twist) with 1/2 MOA accuracy. I killed a 8 point Kentucky whitetail 2 years ago at 612 yards with one shot. Very great load for this rifle. That is where I would start if I were to work with a new barrel.
Finally, I tried 7977 and found a good load. Velocity is 3150 for the 110's with accuracy right at .4-.5 . Fairly temp stable with little change in grouping (moves to a .7-.8 group when it's in the 30's).
