Coming in after all these pages of advice, my $0.02, started with a 257AI in ‘87, loaded Speer 120 BT and took many coyotes, muleys, whitetails, and antelope. Rechambered it to 2506 in ‘15, have it dialed in with 120 Partitions at 3022 FPS. Not really super sexy but nothing has walked away. When I shoot this barrel out I’ll probably look at the the AI version, keeping the same bolt face .
Love my Ackley.
This rifle stays with me when I'm working around the yard or in the shop for varmint duty.
They're fun to shoot and they don't beat the snail snot out of you. I've taken more deer than I can count with either a .257 Bob or its Ackley variant. Now I'm in a conundrum- I just bought a super nice late 70's Rem BDL varmint in .25-06. The original fancy stock was removed when new, stored and never carried. It's got a laminate on it now. I couldn't pass on the price... Here's the photo prior to being shipped. Should get this next week.
I hope I don't forget my Bob.....
I've never fired a .257Wby, but I can say I have an affinity for the quarter bores.
