let me know if you wish to improve the performance of your 25-06 handloads. IMR 4350 cannot be beat for accuracy in nearly ever iteration of 06 cases-necking up or down, but greater V can be achieved by switching powders/primers. ideally the 25s should have a 26" bbl to begin with. That alone will get you 100+ fps. the .257 AI will drop a deer like a bad habit out to 300 yds (just like a Wby.) After that, it'll take a few steps and fall over (out to 850.) Pressure causes Velocity. That's it! Off the top of my head, V killers in a 25-06 would be a 24" factory gun, with one of the last chambers reamed before the tool was thrown away. They are Not all the same...A custom one-off is perfect ev time.
