I just recently aquired a K98 Mauser BCD 4, but am confused on the exact caliber....I didn't purchase this as I inherited it from my father-inlaw (also my best friend) whom lost his battle with brain cancer at a ripe age of 52.....Sold most of his collection to pay medical bills.

After a little google-foo, it can be either 7.92...or actual 8mm.

I looked over the rifle and didnt see any caliber type markings.

Would any of you have an idea, or point me to a good resource for K98'ers?

Most of what I've come across is gun auctions sites and other crap...but nothing really hardcore about k98's
