I shoot Hevi MagBlend 5,6,7 3" with a .670 Kicks choke and get 253 hits @ 40 yds. No doubt I could kill them at 50. Them Kicks chokes are wicked in some guns. I'm shooting an SX3. A friend of mine has a 835. He turned me on to Kicks chokes. The last hunt we went on he killed a bird at 56 steps and it tore his head up. He shoots Winchester HV #[email protected] inches.
