Anybody have experience or know how the system to regulate the Blaser S2 Dobbel riffel work? Best Regards Per

What are you trying to change, the l/r or the elevation?

Do you mean the smaller calibers with the adjustable muzzles? I know someone who knows all about that.

Shots from the left barrel hits right of shot from the right barrel, approx. 30 cm / 100 m Hight ok

It`s 500/416 NE 3 1/4

It sounds like the shots from each barrel are "crossing". That's usually an indication of a higher velocity than the rifle was regulated for. If you call Blaser USA in San Antonio, they may be able to tell you what ammunition the rifle was regulated for. What are you shooting in it now?

When the round was developed, Norma was the only manufacturer making ammunition. I imagine that's what it was regulated with.

Clausen
The S2 that I had, had a wedge under the rubber "rib" on the bottom that you could change regulation with. If the barrels are crossing, you would need to loosen the screws in that wedge. I don't know how much to tell you to loosen them and if doesn't have the wedge, I think you would have to get it back to Blaser and let them regulate it for you.

It has an ajustable wedge, I have reloadet the ammo and it is testet/ same speed and weight as Norma, ps same happens with original Norma ammo, "cross fire"

If loosening the wedge doesn't help, I'm afraid a trip to Blaser might be the only answer.

Andre' at Blaser USA in San Antonio will be able to get it working well for you.

Nope. Krieghoff developed the round and the ammo was loaded for them by Wolfgang Rommey.

You're right....my bad. I had one at one time....only saw Norma ammunition.

The ammo that I got from Krieghoff was always WR. This was 15 years ago. Do not know about now.

Thanks for all your replies, unfortunately had to adjust it with mechanical impact..... Best Regards Per

I saw one of those mechanical impact machines at the Mauser Factory museum in Oberndorf Germany a few years ago

It was actually a barrel bender, a big wheel with a groove and a long lever for bending barrels. The operator got pretty good eyeballing the barrel and bending fractions to straighten them out. I thought I took a picture but can't find it, but thought it was pretty interesting to pass along. Maybe Blaser has one.

I tried, and tried regulating an over under Blaser in 375 H&H Magnum with 235 grain bullets.

Never managed to get less than 6 inches apart.

This one had some sort of screw by the muzzle for adjustme.

Would not get any closer!

Saeed, was there some reason you were loading 235 gr bullets in a 375 H&H? I doubt any 375 H&H would regulate with bullets that light!
All my 375 H&H rifles are loaded with 300 gr softs & solids no mater what I'm hunting.
I have zero experience with any Blazer rifle of any kind, however!
