What happens to the POI past the 30 yards, and how would you compensate for the longer distance ( kind of why I asked about testing each barrel individually)?
Hello Tom Findrick,
Thanks for the reply.

gunmaker answered your question precisely. Saved me having to explain "parallel" groups - muzzle distance apart - forever. Only a a very few of my 29 Double Rifles actually shot parallel.
