Just finishing up my 28 gauge CZ Bobwhite. I installed a Grove Tec sling swivel kit today. I made an rmr mount, drilled and tapped my rib, and installed a Holosun 407. Ended up vinyl wrapping it with OG bottomland. The gun shoots good, POI is spot on. I'm using a .515 Trulock in the left barrel and a modified Trulock in the right, both extended versions. I'm shooting Fiochii TSS 1 1/16 ounce 9's. 178 pellets in a 10" circle at 40 yards. My short barrel shot a nice even 16" round pattern at 30 yards. I may try some 1 3/8 9.5 Apex in my long barrel to see if I can improve my numbers at 40 but completely happy with what I have. I would like to thank some of the members of this site for shortening my side x side learning curve. Especially Crow and Doc Holliday. If I can figure it out I'll try to post pics. Thank you
