I use a 20-gauge Winchester SXP pump and 1 5/8-ounce Apex #9 TSS through a standard full (.030 Trulock extended) choke. Puts well over 100 in a 10-inch circle at 40 yards. I strive to keep shots under 40 yards, by careful choice of set-up, but have killed 2 at 45 steps when I was off with range estimate. I don't use a choke tighter than full because it makes it too easy to miss one that shows up a little closer than expected. I don't pattern before each season but I do check the point of impact using a dove load. I use a red dot sight and love it.
