Re: Considering 25/06 as a varminter
Hired Gun, It is great to hear yet another satisfield 25/06 AI shooter. I have been using rifles (currently 2) chambered for the 25/06 AI since 1986, and like you have grown to love it. I vividly remember my eldest son (about 16 at the time) declaring one night "I swear I am going to marry this rifle some day", after shooting nine big buck Kangaroos (about 7foot tall) without a miss.
Similarly, although originally achieving 3,600+fps, I settled on about 3,550 fps with the 100 grain bullet for my field loads, and sustainable case life. I originally used the Nosler Solid base, spire point boat tail, before switching to the Ballistic Tip, but with either bullet had no trouble achieving sub 0.5 moa.
Your 3,600 fps velocities with the 110 Accubond in the 257 Weatherby are a revelation, impressive, encouraging, and are in line with what I always thought this case should be capable of.
I have never owned a rifle using the 257 Weatherby, as over the years, I have noticed that very few rifles chambered for the 257 Weatherby, seem to exceed 25/06 AI velocities by more that 50- 100 fps, despite a 12-13 grain case capacity advantage.
My gunsmith who had chambered many customer rifles for the 257 Weatherby, believed it was due to the softer brass being used, and the subsequently lower chamber pressures. I guess that prompts the question, what cases are you using, and also what is the barrel length? The photos reveal two impressive and lethal looking rifles. Regards, Brian.
