How hard is it for the .450? Will be doing some research into both. .458 apparently does a good job with the 300gr ttsx.

The 450 Bushmaster is essentially a 284 win cut off at the shoulder with a small primer pocket.

You can't cut the 284 win brass down easily however because the brass is too thick & would need reaming or turning

Hornady make the Bushmaster brass & there was some loaded ammo available 250 FTX at an advertised 2200fps out of a AR

The Yanks are loving the Bushmaster in the AR shooting all sort of stuff like Deer, Pigs, Elk & Bears.

Looks like from my research the BM will work in a rifle using the 243-308 case.

I will be building them on Tikkas, Rem 7 & 700.
