I called the gunsmith and asked him if he had made a mistake in putting a 12 twist on the gun, he just laughed softly, and said, "I want you to load this exact load, 63g R#25, Win Case, Fed 215, 100g Sierra Flat base, and second load-58g of R#25, Sierra 117g Flat base".
I thought to myself, "this guy is smok'en crack".
Off to the range I go.
Loaded the 63g of R25 with the 100g Sierra flat base. After a three shot sight in, I shot the group with the 63g load, and all three bullets touched. Ohler 35P said that it was 3603-3615 fps, and bullets were touching at 100 yds.
There was no pressure with this load at all.
Next, the 58g of R25 with the 117g Sierra flat base chronographed at 3350 fps, three shot group was in the fours, chomping on the heels of a max load.
I could tell that the chamber was minimum spec with a very short leade.
I don't know if you could beat these velocities with an AI or not.
Thanks for the feedback. I would like to get this thread back on track of the topic. If you have any specific feedback for 25-06 vs 25-06AI please post your opinions. I am not interested in any other calibers.
