Jack: Thanks. Yes, in my experience, continental guns tend to be more tightly choked, compared to American and British guns with the same choke designations, Browning being a good example of this. Not sure how Japanese guns compare. Just as an aside, I've also heard that Winchester chokes from the great modern era (approx. 1925-75, maybe?) are typically very accurate and well-bored. TT
