I'm usually the guy who sticks up for the person who wants to do something that collectors would abhor to a gun they own. I figure that if it's their gun it's their property to do with as they choose.
That said, don't you think you could spare the 94 from your "testing"? They're pretty uncommon and I'm sure you could find someone who would be very happy to purchase it from you. Besides, I'm not sure why there would be a reason to expect any significant difference between the strength of a 94 and a 96 Swede.
