RE: 22 17 22 250 which one
That 28 gauge can be used for turkey, Winchester has some 1oz loads of #6. I patterned my 28 with the Win loads and it weren't too bad, not as good as a 20ga but if you keep the range down to 20 or so yards it would be better than a 410 for sure. And I've been able to find shells for the 28 cheeper than for a 410. I really like the 28, too bad it isn't more popular. Last year one of my hunting partners killed a turkey with a contender 410 pistol, I think it was a lucky shot but he did kill the bird.
