I couldn't remember if I posted this before but since TSS isn't cheap I figured out a way to test penetration and pattern at the same time. I took my turkey head target and backed it with my magazines and catalogs. After patterning I realized that I could pull the head pattern off showing just the shot that hit the head. Pretty interesting. This was at 40 yards using Apex 9.5 with a Rem XF choke that measures .526" . Obviously a dead bird. In fact I killed a bird not long after this using this set up.
