Adjustable barrells on a DG
      #33198 - 16/06/05 07:04 PM

Hello Gents,
for the last couple of weeks I have been playing with my new Merkel 141E in 8x57 JRS.
This is as some of you already aware of the most recent adding to the Merkel line of DG. As it's based on a 28 cal action it's only chambered in chamberings up to and including 9.3x74R.
To my knowledge this is the first DG with barrells that's manually adjustable both in the horizontal and vertical plane (without any real regulation as in soldering )

And I must say that I'm really impressed! When I bought the gun it was regulated for 196 grain bulets at 2300 fps, which it shoot very accurately (6 bullets at about 2MOA at 100m).But when I loaded the 196 grain bullets to 2450 fps each barrel still produced good groups ( about 1-1.25 MOA) but the where crossing with about 5 inches and the right barrell printed about 1.5 inches high.
After some tweaking I have been able to get the groups down to under 2 MOA at 100m So I must say that I'm very pleased.

This is my first experience with adjustable barrells (or muzzles), but previously I have seen a lot of people on the net saying that "adjustable barrells is not a good idea" and that they probably will be shoot loose over time and so on.
What is your opinion and what kind of experiences do you have of this thing?

Best regards,
Henrik

Henrik,
As far as conventional double rifles go (sxs):
The Krieghoff is adjustable in it's horizontal plane but not vertically and only up to 375 H&H. The Blazer S2 is adjustable but I'm not sure in which directions. There are other guns around that are adjustable, the Valmet and Tikka. The adjustments are generally simple and not a complicated devise by any means. I can't imagine any reason it won't hold up over time.

The Sig S2 is adjustable in the horizontal plane only.

Yup, my Valmet adjustments hold up just fine, though not really a true DG rifle in many peoples mind.

Around 17 or 18 years ago I had a CVA muzzle loading rifle with adjustable muzzles. Biggest problem with it was that at the time I was woefully ignorant of how a double regulates and suspect other owners were afflicted with the same problem, accounting for its lack of success.

With a very mild load it shot wall eyed beyond the range of adjustment. At the time I though the heavier the load, the greater the recoil, and the more a rifle would shoot wall eyed. For this reason I gave up on it. Not until later did I learn of the importance of barrel dwell time to the regulation and that a hotter load might have brought the groups together.
