450 ACKLEY MAGNUM
The following data was developed in a Remington 700 rifle with a Lilja 25-inch barrel. The barrel had a twist rate of 14. This is the same barrel we used to develop the 458 Winchester magnum data in. We thought it would be interesting to see what sort of velocity increase we could get out of it.
We used the Winchester large rifle Magnum primers and Remington 416 Remington brass throughout our tests.
