He wasn’t to know either, as I just asked for a spec check and visual inspection check over that it wasn't flogged out and cactus before shooting it.

So far it owes me 450$, so it’s not the end of the world.

That's a zastava Mauser bolt.

Definitely do not give up on it yet. My bet is that a full length sized case will chamber perfectly and the problem you are having is the miss match between US specs (the gauge) and Continental (the ammo). A handloader is your best bet of sorting this out. Rounds that fit perfectly in my 6.5 T3 would not chamber cut to match the Redding FL die. There was an article about miss matches with the 7x57 in a recent Handloader or Rifle Mag.

As luck would have it there is a die set right under my nose, and late 70s early 80s so period correct for the rifle.

I’d like to see if today I can get it improved, but I will pull apart some of those factory loads and resize the brass ect, and assuming you are on the money, it should be shooting in no time.

A pain to be sure not being able to use factory ammo, but if it shoots as good as I’m lead to believe older ZKK series does it will be worth it

Sounds like you got conned, first time for the rifle and 2nd time by the gunsmith.

Acquire a headapace gauge and check it yourself. This is a simple thing and if I paid a 'gunsmith' any money I would be expecting any problems to be unearthed, diagnosed and sorted.
