did they at least bend the bolt and do a good job on the blueing?
You can pick up a military vz-24 for about $75. If its any consolation, Vz-24' s ar ereally well made rifles-CZ did make some of the finest model 98 rifles. If it looks nice, it shoots nice, and you like it, its probably not too bad of a deal for you.
It is the standard 8x57 JS round its chambered for.
For ammo, I would shun the remington or winchester crap- its loaded to specs about equalling the 30-30. Order some sellier and bellot ammo or even some of the more expensive stuff from Mitchell' s mausers- its loaded to what an 8mm is capable of. Better yet, the best 8mm ammo comes from reloads
If you want to practice for very cheap- get your hands of some turkish surplus- usually can be found in some sporting goods stores for $5-10 for a 70 rd bandolier, or order some of the better romanian surplus 8mm for about the same price. You won' t get the best accuracy, especially with the turk ammo, but you will be able to make milk jugs explode in a spectacular manner out to fairly long distances. Make sure you clean the bore with windex immediately after a range session, followed by a regular cleaning at home.
