I work on a ranch for a high net worth guy, and he calls the other day to ask if I would sight in a new double rifle he has for an upcoming boar hunt.

My question, is there a proper way to sight in a double rifle? I took it out today to shoot it and at 100yards I zeroed the primary barrel but the secondary barrel consitantly shot a 1/2" low and 2 1/2" left. This is the first time ive ever even handled a double rifle, and dont know anything about them. Should I zero it like I did or split the difference?

thanks

Most good double rifles barrels are regulated so the bullets will cross as some point. If I remember correctly it's usually between 50 and 100 yards (DEPENDS ON CAL.). You can't fix the low but you can get them shooting closer at 50 or 75 yards.
Your right barrel should shoot to the right at lets say 50 yards and to the left at 100
Your left should be left at 50 and right at 100. THESE ARE NOT SET YARDAGES I'm just giving you an idea of what should happen.
Hope this helps.

Well that makes a differance. I don't have any idea how the barrels are regulated on a OU. That is just the way the barrels were made and you can't change that. Is it a Kreighoff?
 
Its a beretta 9.73 x 74 . Would you just zero the primary and hold accordingly with the secondary? or split the differance between the two?
 
Yep, get it reasonably accurate at expected range. I believe the only way to do better needs a pretty good smith to repeatadly pull and reset the barrels and spacers until its right.
