28 gauge Parker choke boring/testing

[Pa SxS]

Here is a good example of what I mean about how the placement of the book on the copier was critical. The book could have been placed just a little more to the left and still copied the first left hand column which tells the grade and barrel steel. Also, note that the pellet counts are always ending in either a 0 or a 5. Did they really count those pellets or just guesstimate? They probably just rounded up or down based on a guess. All those 12 gauges in a row couldn't have all been 250 pellets!!!
