sorry to hear about your issues.
but what it comes down to is you are just small potatoes and probably not even that.
Same with CZs. Small potatoes. if it was the other way around then, yes, they would cater to CZ and you, but its not.
also, sometimes its the shape of the bullet that may or may not make a difference.
you are better off using the ammo in some other gun.
Also, thinking outside the box, ever consider having your chamber redone or maybe a new/different barrel?
good luck
