I'm not interested in stirring up a TSS debate on lethal range. I have a 20 ga 870 that's a joy to carry for turkey. Anyone used 4s for coyote? If so what choke?
The TSS #4 shot has worked good on coyotes for me out of Carlson's Extended Sporting Clays chokes in Modified and IMP/MOD.
TSS shot is perfectly round and stays round so it patterns much tighter than most lead shot loads.
The below is from KPY Shotshell Ballistic program. I use 3.70" of gel penetration for killing and knocking down coyotes. KPY recomends 2.50" of gel penetration for killing big geese.
1250 fps lead BB shot gets 3.70" of gel penetration at 43.7 yards with 51 pellets in 1 oz.
1250 fps TSS #4 shot gets 3.70" of gel penetration at 76 yards with 83 pellets in 1 oz.
I don't plan on shooting coyotes at over 50 yards away but that extra penetration sure helps when the shot angles are not good at 50 yards and under.
