Ruger American 450 Bushmaster can I use 460S&W load data?

[Camp Cook]

I just recently purchased a Ruger American bolt action rifle chambered in 450 Bushmaster.

I already load and shoot 45 Colt and 454 Casull and have several thousand 200gr FTX - 535gr Ranch Dog WLNGC and almost everything available in between.

I'm trying to come up with load data for my heavier than 300gr cast gas checked bullets and really haven't had much luck.

I started thinking that the 460S&W case is fairly close in size to the 450 Bushmaster so I have to ask can I use 460S&W load data?

I will be using this rifle for still hunting in thick bush for deer where shots will be max 250 yards.

I will also be loading this rifle for my wife to use for camp defense.

I installed a Leupold VX2 2-7x33mm long range reticle scope with PRW rings.

I appreciate any thoughts - opinions you care to share.

disclaimer - I am not new to reloading been doing it for over 35 years I load for over 20 different cartridges now.

4227-33.9grs

Win 296-34.5 grs

Hope this helps.
