If the ammunition is safe to use in Turkish-issued bolt rifles, in all of the various versions and states-of-repair you are likely to find those in (not really including use in the old M88 actions, though), HOW is it going to be dangerous in any other bolt action.
The powder in that Turkish ammunition is slow-burning. In theory, it gives you no higher a peak pressure than the limits for the cartridge. The trick is it maintains that pressure longer, producing a higher muzzle velocity. This is how they could get muzzle velocities of 3000+ feet per second pushing a 150 grain bullet out of a 30-inch barrel.
You can do exactly the same thing with slow burning powders that you readily find in your reloading manual (IMR 4831, for example), but somehow if it is 'in the manual', it is somehow OK. If the Turks loaded it, though, the story is the world is going to come apart at the seams.
Nature has supplied this planet with a virtually unlimited supply of a chemical that is totally capable of 'neutralizing' (or removing) corrosive primer residue. That chemical is called 'water'. There is no reason to fear using it to clear corrosive primer residues out of your bore.
Shoot the stuff as it is.
The question asked in post #10 is probably best answered by stating that they also used this ammunition in the 88/05's, etc., only with a reduced factor of safety and perhaps a somewhat higher likelihood of 'blowing the rifle up'.
It may be a bit bloodless to put it this way, but it was not likely that they would run out of Turkish soldiers anytime soon from this.
