When I bought my Vinci supersport, I didn't have time to switch around the shims before I used it for a pheasant shoot. I did well at the shoot, but I felt I needed to "target in" my gun afterwards.
I used a fixed target at 45 yards and a stand to keep the shotgun steady. I found the shim "b" it was shipped with to be high and left. I found the "c" shim to be a little high, but pretty close to dead center. I used several shots and three chokes. I felt I had it perfect.
Here is my question. After I changed the shim, and targeted it in for my turkey hunting, I went pheasant shooting again. It wasn't my best day to say the least. Could it having to do with the shim change? In other words, would there be a difference in a moving shot (a bird in the air or skeet) vs. a fixed straight ( a turkey standing in front of my blind) as it pertains to a shim?
Could it have anything to do with the shim change? or was I just having an off day. I am new to this, and would enjoy any feedback as long, as it is constructive.
