Pretty simple really the loading data in reloading guide books are designed around SAAMI spec pressures and those are based on the guns out there. As long as you have M93 & M95 Mausers being used by the public that load data won't much exceed 46,000 Cup. I wouldn't argue that with a M700 Classic your loads are capable and safe. When you look at what pressures that Norma and RWS load the 7 x 57 and 8 x57 compared to RP, WW ,& FC it sure makes you wonder, because they aren't too worried either. LOT TO DO WITH LITIGATION LAWYERS AND AMBULANCE CHASERS mostly at the corporate level. Use good brass and don't get ridiculous either. Lot of domestic carts are underloaded for the afore mentioned reasons( 6.5x55, 257 Robts. etc) Lotta folks here on the fire load the 257 Roberts way over what you find in the manuals. If you have weaker action guns and stronger ones for the same cartridge keep your loads well marked and separate. Naturally if you exceed manual recommendations ,YOU ARE ON YOUR OWN no matter who says what. MB
