Fellas, I don't know how well the captured 98s lock up or how tight the actions are but, of the 4 8mm Mausers I have, two being VZ-24s, one a Yugo 48A and the other a pre-war made K-98, the K-98 is the loosest goose of the bunch. The headspace is good and so is the bore, but she's a rattle trap. The two VZs are better made rifles, both being made before that particular K-98 was, and the Yugo 48A is almost new (excepet for all the rounds I have put through it) and will become a carry around field piece.
BTW, for us 8mm lovers, rumor has it that Remington will be making one of its lightweight stainless bolt rifles in the 8mm Mauser, giving us the chance to compare current production and older world quality. Sounds like fun to moi! Mikey.
