Dan: "The G2 can run faster that (sic) the G1". Mike Bellm agrees with you but J. D. Jones does not. When I was developing loads for a .308 Bellm chambered by Mike he said to use .300 Savage mid power loads. When I discussed the .308 JDJ with Jones his opinion was the G2 action was not appreciably stronger than the G1. Because there is no SAAMI pressure data for either cartridge I do not know who is right. Maybe it depends on how many stretched frames each pistolsmith has seen?
