Thread: 22-250 Ackley Improved Load Development

When fireforming cases sized from 270 to 2506AI, I leave a little 'bump' at the bottom of the neck so that the case is held firmly between the base and the neck bump. The Fireform result is perfect and consistent. As an example of loads, a normal load for a 110 AB is between 3300 and 3400 fps. I load the fireform loads to 3000 fps and just go hunting. For a 22 250 an AB would work very well I think because they can handle and work at a high velocity just as well as at a lower with no blow ups
