Looking for someone who has the QuickLoad program or experience with this caliber.

458 Socom. Cast bullets of 576 gr, no gas check.

Anyone have a starting and max load?

Thanks

I can do it for you with QL and GRT. I need more input data:

Bullet length
COAL or seating depth
Powders you have or can buy
Barrel length and/or rifle type

Optionally, for more accurate results, water capacity of fired case.
