HMMM YOU SHOWING THE BOLT THRUST OF A 460 S&W HIGHER THAN A 308 WINCHESTER???? i dont have the numbers or dimenions handy but that is suprising to me. I thought the 460 was a pistol round and had much lower pressures even though the case Od is larger Id have though it ould be less. I really dont pay to much attention to the IMOO extra expensive pistol rounds like the .460 or the .500 but maybe I should.
Tromix did a 444 marlin on the 410 with out issue BTW. the 444 is loaded tho less chaber pressure than the 308 however.
