Quickload Request

[NYDAN]

Nosler doesn't list any load data for the 450 Marlin and the 300 gr. BST. Manuals say not to use 45/70 gov't. data for the 450 Marlin. Would someone be so kind as to run a couple of projections for me? Thank you.

450 Marlin
24" barrel
300 gr. .458" BST
Overflow case capacity = 76.4 Gr. water
Powders: H4198 & RL 7

Dwh7271,

Thank you very much. I truly appreciate the time and effort that the owners of the Quickload program put into running projections for those of us who don't have it. Every once in a while I will see a projection run for someone else but it is applicable for a trial I have in mind and I print it out and save it.

Kind folks have helped me numerous times when I couldn't find the combination of cartridge, bullet, and powder in a manual. This is one of those times. I feel much more comfortable when I have some guidance from a technical source.

Thank you.

Dan
