Cool video, however his shooting off the bench, I dislike allowing the forend to bounce. I find at 100meters, in my .375/06IMP, which does not kick as much as this .416, the difference
between hand-held & letting it bounce, is 3 1/2" in group location - vertical dispersion.
This shows that allowing the gun to bounce, caused a 3 1/2" higher vertical impact. This difference would not be noticeable at 50yards, but could make a difference at longer ranges.
That Rigby was a beautiful rifle.
