![]() I have found lots of opinion expressed on Internet regarding the conversion of Swede actions to longer cartridges, but not much regarding reference material to support those opinions. The Stiga appears to be built on a surplus Swede 96 made between 19 (the receiver stampings are ground off, but the serial number starts with H.K., which would be Inspector Helge Koltoff - I stand to be corrected on the dates). I own two Swede 96 in 6.5x55, one Husqvarna 648 in 8x57 and now a "new to me" Stiga in 30-06 - all, of course, built on the Swede M96/M38 action. Stiga rifles and European Nito Proof Testing ![]() ![]() Baribal's reply put my "what if" concerns completely to rest. It was of concern to me, because is obvious that there was material removed behind the lower (bottom) bolt locking lug support area in order for the longer 30-06 cartridge to fit. So, there is a rated pressure level that the M96 had to pass for the 6.5x55 original cartridge - then companies like STIGA re-chambered them to other cartridges - STIGA did do the re-proofing tests, and the various stampings show that - other makers, especially from USA, did not. Is a post that I created about a 30-06 STIGA about that very thing - the Baribal guy responded about the significance of the Danish proof stampings - that rifle had to pass 125% overload without permanent measurable deformation - is required in most European countries, but not in Canada or USA - is about what "proofing" means - an engineering concept - is not rated for that level for lifetime - but took that level once or twice, without deformation, which "proves" that the assembly - bolt, receiver and barrel - is good for "normal" rated pressure loads, forever.
