Anybody else on here frequently hunt with buckshot? If so, what load/choke combination works best for you? My 12ga 870 with a 26" barrel does best with 3" 00 winchester out of a modified. Shoots a pattern good enough to kill a deer at about 40 yards, but it is still not quite as tight as I'd like to see. With a life-sized deer poster, it puts about 5 or 6 pellets in the heart/lung area with one or two in the neck and a few in the head sometimes. With a regular full choke, it shoots a doughnut pattern (ring with a hole in the middle). My old 16ga with a full shooting #1's shoots a far tighter pattern than my 12. My 16 consistently puts 8-12 pellets in the heart/lung area at 40 yards, but it is not in good enough shape to hunt with. Can anybody suggest a good aftermarket choke tube/load combination? All imput is greatly appreciated.
