I have a mod 700 long action and am gonna build a new rifle I was talking to my Riflesmith and we went back and forth for a while I was really wanting a .280 ackley but the more me and him talked I think a .257 bob ai would be better for several reasons but the most important one is that my wife can shoot it and with the .257 bob in the long action I can seat the bullet a lot longer I was thinking a Shilen number 3 would work we also talked about a 25-06 but I think a .257 bob ai with a nosler accubond would be pure whitetail death also with the barrel being a little heavier than the factory it will be a little steadier out of the shooting houses I am open to any and all opinions for other calibers let me know what you guys think
