I believe this has already been discussed but I would like to add that sadly I had not checked or read up on steel cased ammo use in the K98. The 8mm steel cased I used was called Hotshot and is made in Romania imported/distributed by Century. Even though it has a different name the rest of the package looks speciously like a lot of other steel cased Romanian ammo so I suspect all made by the same company. It may work just fine in all sorts of Mauser's but in my K98 the bolt became hard to close and hard to open until finally stuck closed on a jammed case. Yes, if I had a clue at the first sign of the bolt behaving differently than it did with brass cases I should have quit but lack of experience and not wanting to quit or "waste" ammo I kept on so tonight I will sit down with the weapon and see if I can get it unstuck. Learning by your mistakes sucks!
