Dropped two deer this year with 250 grain sst out of a 20 ga. both pass throughs, one dropped in tracks the other ran 50 yards double lung and shoulder blade. Both were about 15 yards though.... They are the most accurate of the sabots I have tried with the wife's gun.
[edit] Oops, just realized this was on the ML side. Still nice bullets. I might try them iun my .50 cal next year.
