I decided to build a rifle that would do double duty as a deer rifle and something for Coyotes. I was thinking of punching paper at 300 yards also. I thought of a 25-06 and someone mentioned the .257 Roberts AI and I decided I would try it out as it sounded interesting. I'm using a Savage Model 111 with detachable mag and a Shilen Select Match Grade barrel finished at 24" (1-10 twist light varmint contour). I have a Hogue Overmolded stock (with full length aluminum bedding) on order and have a Sightron SII 6.5-20x50 with mildot waiting on the bench. I also have a Timney trigger waiting here as well. This will be my first center fire bolt gun build and I'm kind of excited. Is anyone familiar with this caliber and willing to comment on what I could expect performance wise and can anyone share some load recipes also? Thanks in advance.
