This is a very interesting thread with lots of great info and I wish I could have read it a year ago before buying the YILDIZ. One thing that I found from it that was very consistent - the heavier the load, the more wall-eyed it shot. As the load increased, the right barrel shot further right and the left barrel shot further left.

The eccentric chokes corrected it somewhat - wouldn't they actually be creating barrel convergence in a sense?

And by the way, the 1.75 oz turkey load at 1100 fps does not have heavy recoil at all. Its not in the same league as a Win Supreme 3.5" 12 gauge load. And you usually shoot no more than one per day, and your heart is racing when you do.:)
