50 yards...

Looks like the pattern is dropping about 4-6 inches from 40 to 50 yards. The black circle is 8". I was aiming at the red dot.
I wouldn't shoot at 50 yards anyway, just being curious.
Nice pattern, I just purchased the Carlson LB choke for my 835. I bought a box of longbeard 4,5, and #6's. I only tried the 6s so far but after seeing the pattern that choke puts out with the 6s I may just stick with them.
