are you talking contender barrels or encore barrels with that much pressure? an encore barrel will handle the pressure but there isn't way I would shoot a round that much pressure with that case head area in a contender barrel.
Check out T/Cs list of barrels. 256Win Mag, 6.5mm Rem and others.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
