Quickload Request

[NYDAN]

I found some Reloder 7 at a local gun store and thought I would try it out in my 450 Marlin. Would someone be so kind as to run a quickload projection with the following criteria?

Caliber - 450 Marlin
Barrel Length - 24"
Bullet - 350 gr. Hornady Flat Point (Hornady no. 4503)
Powder - Reloder 7
O.A.L - 2.530"
Overflow case capacity - 76.4 gr.

Thank you.
