Blow it out like a toad frog, add more slow powder.

I wanted a .257 Ackley, I was thinking more of the .25-06 in the discussion (which is actually over-bore capacity, so I guess technically a "magnum" if you will). The little 6mm Ackley was an OK runner up. I'd not want to shoot anything too big with it but it has some reach. About like the .240 Wby. (that is actually a belted .24-06!).

Nosler lists the .257 AI with a 120 gr. at 3000 fps using H4831C, the .25-06 shows 3200 fps with Retumbo.
