I have a couple of Mauser barreled actions I was given by a friend. One is what looks to be an original 1908 Brazilian Mauser in 7X57 made in Germany by DWM and all of the numbers match. The other is an Interarms Mark X in 270 Win made in Yugoslavia. Can either of both of these actions be loaded to the modern pressure limits of their respective cartridges or others such as a 308 Win? I load my own.
