Shootist, yes, I really want to build a classic 6.5 X 55 Swedish Mauser by utilising the Carl Gustafson action, since it was designed for the Swedish Mauser...I also believe that I will never get dangerous pressures since I will reload to a safe level..the Europeans reload this caliber to higher pressures than the USA hunters/shooters...If the 1917 action was manufactured in 1942 I believe that the steel the Swedish manufacturers used would have really been superior and great quality steel due to the different alloys that was prevalent in those days, the high of the industrial era...Gert, I believe that 1917 was the last year the 1896 Mauser Action was produced. However the Actions of the M-38 rifles produced by Husqvarna are identical. From memory they were produced from 1938 through 1942. That last article you posted was terrific. If you read through the whole thing the "two lug" Swede failed a 100,000 psi. That confirms an article that I read many years ago supposedly written by the head of VV's Ballistics Department that stated that VV's Proof Barrel for the 6.5 x 55 was good for 81,000 PSI and that the action used to fire it was that of an 1896 Swedish Mauser. Some more food for thought is that there is no "pressure relief" hole in the Swede whereas there is one in the K 98.
