Javven, I would look for a reg. lenght mauser 98 action, k98, CZ, VZ since the Yugo is a 1/4" shorter to start , ok if you want to build a .243, .308. 7x57 or 8x57 . On a classic mauser you could fit .270, 06, .280 , 7mm rem.mag, .300 win.mag. and 9.3x62.
Concerning the 9.3x62 cartridge it offer a good knock down power with a 296 grain tip, a little more flat trajectory with light bullets, the rifle itself if I must explain the recoil kick I would say that is in between of the 06 and the .300 and again provided all rifles waight the same and similar configuration.
The choice of the cartridge it depend of the type of usage you want to doo, in heavy timber the 9.3 is excellet , across a lake or long shot 250 300 yrds not so good. I have all the above but end up most of the time taking the .300 win mag to hunt.
