Mike --
I saw the phrase, "Both barrels were expected to impact the point of aim at the same place.", but, did not know what lay behind the assertion.
I assume that the phase means that the Winchester people had a design and barrel joining process which reliabily produced the same point of impact for both barrels.
If true, it is not clear that the important elements of this joining processs are known my all members of the industry, currently.
By the way, it is over a week, now, since sending my note to B. Rizzini, inquiring as to the tolerance for the differential in the barrels' points of impact, which they could guarantee, on a new set of barrels. This inquiry resulted from their suggestion that I could purchase a new set of barrels to resolve my current patterning problem with my B. Rizzini shotgun. After sending the note, I have called the representive twice and left messages. To date, the silence is deafening.
Thanks.
Best Regards,
Don
