Does anybody else load .458Lott with .600Barnes ?

Not yet. I have had some 600gn barnes on order for a while. By the time they get here I will probably have my 458 Lott finished(hopefully).
I know they are bigger than what is needed for most game ,but I will see how they go on scrub bulls. I think most of their use will be on blasting ant hills for practice shooting.

I have shot some. I did not group then and they are long. RNS

I shot some in a 458 win mag. @ 1850 fps and they were accurate.

I put a .41 rem mag flatpoint bullet seater in my .458 dies and it put a nice flatpoint on the bullets.
