Postman,
Thanks for your response, I have often wondered how and if these so called adjustable guns would regulate. The theory is that you should be able to adjust them for different loads and bullet weights, but it doesn't sound to me like Merkel has cracked the code yet. I'm not saying it can't be done, I'm sure somewhere out there that there is a gun that can be adaquitely adjusted at the bench, I have just not found it yet. I am still interested in hearing from Merkel owners who might have a gun that works as advertised and I am still trying to find out how the adjustments are supposed to work. Bob
