Simple ?...I have a ruger 45 colt bisley. Thinking about getting a second cylinder for it and reaming it to 454casull. Can the BH Bisley frames handle 454 pressures, or would I have to upgrade to the redhawk frame? Currently the strongest factory chambering in the Bisley BH I could find online is the 44 mag with a max sami cup of 36,000 where as the 454 casull has a max cup at 65,000. So I was wondering just how much pressure is the BH frame rated for? According to HP White laboratories the Ruger .45 Colt destroys itself at about 65,000 CUP. Any info would be much appreciated Cheers, BR
