    Default 460 and a 375 van horn

    Im hopeing someone here will know something about these calibers as l have a 460 vanhorn which is a 460 weatherby cut down to 2.50 inches and l do have some reloading data on it but not much,l did find some info on it based on the 458 lott ,useing the 458 lott data 5% less to start and go up to 8% higher its based on a 1908 mauser with a 26 inch barrel,,lm shooting 350 grain hornadys at close to 3000 fps with 90 grains of imr 3031,l know they wont stand up to nothing as they would fly apart but l have to start somewhere with the data l have ,and lm also looking at the 375 vanhorn ?any info would be very much appreciated on any of the calibers

    The 460 A-Square is essentially the Van Horn with very minor changes that wouldn't affect loading. The data can be found in "Any Shot You Want", A-Square's load manual.
    Original information on these can be found in the Wildcat Cartridges, Volume II published by Wolfe, but those articles didn't use pressure testing equipment, while the loads in the A-Square manual were developed and then published with the pressures. Much safer than guessing about converting from a different cartridge.
