Carl Gustav and Husqvarna M38 actions are much stronger than German actions, not only because of construction, but mainly because of the steel used and the more recent date of manufacture. An M38 action is actually an improvement over the original Mauser 1894/96 types. They are not the same actions! Oberndorf = Mauser, M38 is Swedish national production.

Its unsafe to push this cartridge beyond Military specifications and totally useless to do so. The 6.5 x 55 will not be very much more effective, its rather good as it was designed.

Old parts & and more power usually don't add up to a good idea, remember the 94/96 have the nasty habbit of NOT directing hot gasses away from your face when a primer ruptures. Powder burns don't win you beauty-contests and hurt like @#4!!!&the rest!

kind regards,
