You have a point, Mike. The 28 bore is particularly liked by a close friend of mine. He bought one of the Turkish O/U's a few years back when they sold for $450.00. They are now $649.00 and I am thinking along that line myself.
Much superior in patterning to the .410. For me, both .410's I patterned, did better with 2 1/2" 1/2oz. shells than the 3" 11/16oz magnums.
The 2 1/2" gave much more even patterns, whereas the 3" gave a centre concentration of shot, this tiny circle of densely patterned shot with a huge wounding pattern around it with scattered shot.
One of my daughters has a .410, stored here until she acquires her federal license to possess a firearm.
I have a ventilated rib single shot folding .410 that is likely too tightly choked. I need to open that up a bit as it shots poor patchy patterns with all the different loads I've tried, 3" and 2 1/2". BTW - .410's used to be cheap - not any more.
