I owned an R 93 a few years ago, thinking like most that it would an indestructible piece of hunting equipment for rough conditions where I didn't want to take any " decent vintage" items.
Mine , a 7X64 backed out primers from day one. Took it to Africa ( along with a vintage WR 500NiTRO), came up on a Wharthog, closed the bolt and it went " click"
I waiting wondering if I had a hang fire, and finally with baited breath opened the action. There was a very slight indentation on the primer .
Took it back to camp, threw it in the tent , and picked up my 100 year rifle.....problem solved.
Rang the agent upon return home. They informed me I didnt have the action closed properly!!!
I do admit there is a very small amount of " feel" as the action locked, however it was closed sufficently to let the firing pin fall, at least some way.
Following week had a phone from A senior manager at Blaser who kindly offered me a full refund....I took it.
It was and is IMHO a piece of shite.
Whatever pocessed me to use anything other that a conventional turnbolt action, I cant say. I can only say that I too was taken in by all the BS that is written about them. Lesson learned.
To be fair the later model may be different , but I never want to find out, but no doubt the R93 had serious issues.

As for taking one to Africa......never again any engineers rifles for me..
