Mac,
Thanks for all the information. To answer some questions: The gun was restocked left handed. The barrels still fire right barrel first (front trigger) then left barrel (rear trigger).

The 470 set of barrels are dead on as they were, regulated at 50 yards. My shooting and the targets included were identical. The 9.3x74R is a tack driver at 100 yards 6 shots total r,l,r,l,r,l the right barrel has three touching and so does the left about .5" apart vertically.

The barrel set in question is the 7x65R. At 25 yards my first time shooting the bullets were crossing. In the second session at 100 yards the left barrel crossed the right barrel by about 4". I turned the adjustable wedge and they came apart and are directly over & under each other at 100 yards. I don't seem to think the gun is giving what I'm expecting out of this caliber. After a 10 shot string. r,l,r,l etc. the right barrel put 5 round in 1" and the left barrel put 5 rounds in an inch.

The question came as the two barrels were 1"-1.5" apart vertically. The right barrel shot high and the left barrel shot low at 100 yards. I think this is fine for hunting. But I was wondering what effect different bullets and speeds had on the vertical separation.
