.... Being on a "fixed income" and really wanting a 7x57 Mauser, ever since as a kid I devoured stories of "Kilimanjaro" Bell, I need a cheap rifle. Is it a viable and low cost conversion to obtain a military barrel in 7x57 (and if so whats the most accurate?) and screw into into an Israeli M98 in .308? I'd assume that the magazine and extractor would work OK, as being roughly the same length? If this is not a viable option, then guess I'll save my pennies and "spring " for a Ruger SS in 7x57 ! Thanks for any input/suggestions, as long as it doesn't involve giving up on getting a 7x57 (I just want one to shoot !) ...David K.
