Thanks to Sumtoy chokes for quickly getting a choke shipped out here to Oregon, he literally had the choke in the mail hours after I'd ordered it. It fit perfectly so I took it to the range today to pattern it with two loads: WLB 3" #6 1 3/4 oz and WLB 3.5" #6 2 oz I shot them out of my Xtrema 2 with a 28" barrel and the Sumtoy .665 choke using a Vortex Venom red dot. The 3" load and choke produced a pattern that had 183 pellets in a 10" circle at 40 yards. A turkey killing pattern for sure, but we're all looking for perfection or close to it. I loaded up the 3.5 inch loads and holy cow! I got 256 pellets (the picture says 245 but just to the right of the tape is a group of 11 that I didn't mark or count) inside a 10" circle at 40 yards. I'm beyond pleased with the pattern this gun now throws. Thanks for the great choke and exceptionally fast customer service.
