I've not heard that Savage proofs every gun to 129,000psi and I would be shocked if they did. That pressure is approaching the yield strength of the steel so I'm not sure I would purchase a gun that was subjected to near failure pressures as it may have been compromised in the process.The only test I've heard of that mentions that figure was done on a section of Savage barrel that was capped at both ends and set off like a pipe bomb. The barrel peice survived and all the pressure was vented through the ignition hole. Definately shows the steel is strong but I still wouldn't buy a gun that was put to that test.
