Hi Guys- I'm a regular over at the H&R single shot rifle forum and I just bought my first Mauser and need some help. My rifle is marked as follows: left side of the receiver -Mod. 98,top of receiver-dot with 1944 below it. The serial #49XX appears on the barrel ,bolt, and safety. And there is a crest on the barrel following the serial that looks something like an eagle with it's wings open. The barrel is 23". What do I have? I know it is 8mm but how do I know if it is the one with the .323 bore and can I use current factory ammo? Thanks Guys for the help, I'm excited about my new purchase ($75.00 from my brother in law ) and I'm anxious to learn about it!-jeff
