I have some data from P.O. Ackley's book. pm me your email & I will scan the 2 pages & email them to you.

Worked up a load for a friend using IMR4350 w/65 grs @2,900 fps if I remember correctly. 5 shots touching at 100 yds and was a pleasure to shoot. Brass he had was 7 mag expanded and shortened about .25 inch to headspace in the gun.

He took 2 Caribou at 400 yds with one shot a piece and was pleased.

Don't forget, the 300 Ackley is a wildcat and comes in many different sizes and shapes. If you do not have any fired cases it would probably be a good idea to make a chamber cast or run a Magnum cases into the FL die to see exactly what you have.
