When I bought my ZKK602 .375 H&H in 1970, it came with an imitation Weatherby stock, adorned with contrasting foreend tip and pistol grip cap and other abominations, clearly intended for the American market. This was odd, because I bought it from Waffen Frankonia in Germany. I assume your rifle was not similarly stocked.

Whatever its origin, the result is admirable, and evidence that you CAN make a silk purse out of a sow's ear.

I wonder how you went about converting the single set trigger to direct pull. Did you simply substitute the factory supplied direct trigger for the set trigger, or did you have to fabricate something? The reason I'm curious is that I have a ZKK600 action with a set trigger which I would like to convert to direct pull.
