QL request, 450 ULT

mjcmichigan · May 8, 2019

It’s a JGS cartridge. Basically a 375 RUM, necked up to 458.(I think fireforming is required as well for shoulder and diameter.)

Would request the overview of powder selections.

Hornady 500gn DGS

Barrel is 26”.
CCI large rifle magnum primers.

Remington cases. Will get some case volume measurements when I get them from my buddy.

Should be an interesting project.

Use 458 Lott max loads and work up

Dwh7271 · May 9, 2019

OK. I went into QuickDesign and loaded a 375 RUM and necked it to 458. Loaded it in QL

Code:

Cartridge          : 458 ULT?
Bullet             : .458, 500, Hornady DGS 4507
Useable Case Capaci: 99.845 grain H2O = 6.483 cm³
Cartridge O.A.L. L6: 3.600 inch = 91.44 mm
Barrel Length      : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 62000 psi, or 427 MPa
or a maximum loading ratio or filling of 108 %
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
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
