Buffalo Bore’s 7B20 “Personal Defense — Strictly Business” load pairs a heavy 300 grain semi-jacketed flat point bullet with moderated pressure in the .454 Casull chambering. Buffalo Bore does not load this cartridge to its maximum pressure for this bullet weight in order to maintain reliable function and manageable recoil. The manufacturer notes that at upper pressure levels heavy bullets can jump crimp and fired brass may stick in chambers; this load is produced to avoid those issues while delivering substantial muzzle energy. Product packaging is 20 units per box, with 12 boxes per case for bulk handling.
