Cricket, I love SxS's and I love 16 gauge. In Alberta 16 gauge shells are not hard to obtain, even CanTire stocks them. A 16 will throw a better pattern than a 20, and a 1 ounce load of 6's or 7 1/2's will bring down anything the uplands has to offer. Target loads for the 16 are not generally available, if you plan on using the gun for extensive skeet shooting you have to become a hand loader. As an upland hunting gun, occasional clays use and even a bit of duck hunting, the 16 is an ideal guage. In a double, it can make a fast handling, well balanced gun with few peers. Don't get a 16 gauge built on a 12 gauge frame - the magic disappears, and you may as well get a 12. For under $1K, you can have a scaled frame CZ / Huglu in 16 ga. If you find a nice English example, don't buy it - call me, I'll buy it and test it out for you.
