I have had one of the AYA Lightweight 10ga 3-1/2" for a few years now. I corresponded with eightbore about his and if I should worry about shooting steel out of it. At the time I measured wrong, I told him the gun was choked 0.025 in both barrels. Turns out I was wrong, both bores are 0.772 with .045 choke. The rib is marked Full & Full, they weren't kidding. 32" bbls. and weighs 9-10.
I took it out last week for the first time and used 3-1/2" Black Cloud Steel BB's and Canada geese fell like stones. I'm either going to have to open them up or shoot further....birds were pretty torn up at 30 yds. And I have to admit, less felt recoil than some of my 12's.
Maybe adjust the chokes and put swivels on it.
