Let me preface this with the following: Yes, I know by the time I do all this I could have bought a brand-new rifle and saved money. That's really not the point :wink: I'm planning to, over time, make a thoroughly custom 98 mauser-based sporter, with a wood or laminate monte-carlo stock, sporter-contour replacement barrel, scope mount, glass-bedded action, replacement trigger (either Timney or Huber) etc. Now, the question is, what cartridges can the 98 be safely rebarreled to? I know magnum loads will require a new bolt face, but I don't really need magnums for any of my hunting anyway. Second, is there such an animal as a "drop in" replacement barrel, or is this a job that pretty much demands a trip to the smith? If the latter, how much should I plan to shell out?
