I had my winchester 23 heavy duck measured on friday.
Left bore .727
left choke .717
right bore .733
right choke .723
Is this common? Before I had bores checked I just assumed IC and Skeet from measuring the choke only and the pattern board supported that in my mind. The left barrel patterns tighter than the right barrel on the pattern board. The left also is about 3" right of center at 40 yards, but has not seemed to be a problem shooting sporting, skeet, etc.
