I recently acquired a K98, 1944, rifle. It was mismatched parts but looked to be in good condition. I cleaned the rifle and was able to take it to the range yesterday. Things did not go great, and I'm hoping some of you might have some ideas on how to proceed. 1. loading 5 rounds in the mag led to some chambering issues. Basically, the gun was having trouble when the round was on the right side. I'd have to start loading, then back up the bolt and slam it home. When the round was loading from the left side, sometimes it wouldn't pick up the round at all and I'd have to scootch the round up a bit and then the bolt would take it. 2. First go was 5 rounds. Then a few minutes later I started doing four round sets. On the 10 round, the bolt started to stick extracting the cartridge. On the 11th round, it locked hard. Could not get the bolt open at all and eventually had to force it open a couple of hours later in the garage. Doesn't seem to be any damage, and the spent cartridge wasn't warped at all, so not really sure what was going on. My first thought was heat expansion...this is not a matching serial rifle, so perhaps that could be an issue? Clearly this is the main problem and I need to address if I'm going to keep this rifle. 3. The rounds weren't grouping at all. Was firing at 100 yards and it was hitting high and to the left. However, even knowing this, I could not really get any sort of consistent grouping. Granted, I didn't get to fire that many rounds, but I should have seen some grouping once I was correcting with my aim. Any help at all with the bolt issue would be greatly appreciated. Also, any info on pricing for gun smiths if I have to go that route would also be great. I didn't spend a whole lot on the gun, and don't really want to sink a bunch of money into it.
