As discussed in: This Thread I finally got to run some ammo through it. 
Range conditions were not too good. 14 kt current about 8 feet deep running from right to left but steady.
Had to go to plan B for a place to shoot because the Mississippi River was a little high for me. I fired 210 rounds of IMI ball with nary a burp.
DISCLAIMER I in no way would suggest that anyone else on this board attempt a project like this.
