I could not find a correct diameter 300 gr, so I grabbed something close and ran it at the higher pressure.
I could make more runs, but would prefer you to narrow down the scope and/or improve the inputs a little.
Code:
Cartridge : 11.2 x 60 Mauser/Schueler
Bullet : .452, 300, Hornady XTP MAG 45235
Cartridge O.A.L. L6: 2.765 inch = 70.23 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Maximum Pressure: 35000 psi, or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
