The Kick's Buckkicker is usually about Improved Modified for your particular guns barrel constriction. That should be about .025" constriction from your nominal bore size. The longer ported choke theoretically should improve patterns by stabilizing the shot for a longer period of time and adding more gradual constriction and by retarding or stripping the wad away from the shot pellets as they exit the bore. Works great as long as you aren't using a shell with the Flight Control wad system. A load like the Federal Tactical with Flight Control wad will usually do best with a choke with a little less constriction and one that doesn't strip the wad.

00 Buck has a problem in that the pellet count is too low to keep the pattern concentrated at long ranges. The gaps between pellets gets too wide and fewer pellet strikes means less damage and effectiveness. Number 1 Buck is a big step toward a better load in normal lead shot pellets. A 2.75" No. 1 Buck shell has 16 .30 caliber pellets to compare to the 00 Buck 9 pellet load of .32 caliber pellets. More pellets of nearly the same size tilt the odds for multiple pellet strikes heavily in the No. 1 Buck's favor. Number 4 Buck works great on coyotes and such. No. 4 Buck is a .24 caliber pellet and the 2.75" load has 27 pellets. The 3" 12 gauge No. Four Buck load of 41 pellets has been a coyote hunters favorite for a long long time. The FBI used to issue the 27 pellet No. Four Buck load but quit after several shootings in which they cited limited penetration of the smaller .24 caliber pellets caused poor immediate incapacitation of violent suspects. Take that for what it is worth to you for your situation.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
