Hi Captain, My name is Karen, and if you hog out a perfectly good 8x57 to a 9.3...I will suffer great emotional distress. On a more serious note, if I was contemplating that, I would load a dummy round 8x57 with a heavy bullet seated out to an OAL of something like 3.3" (to kinda replicate 9.3x62 length) and see how your mag and action length function with it. I have been cobbling up Bubba sporters on Mausers for many years, one thing for certain, when you start to mix and match cartridges and actions, you soon discover nothing is for certain. Somebody estimated there were 14 million Mausers built in the last century in 40 or more different factories, a playground for Murphy's Law.
