Well, have killed 21 deep with the .45ACP...most of them while shooting a LSWC #68 H&G design over 5.8 gr of WW231...velocity of about 900fps...all close shots, none more than 40 yds and only two required more than one shot..small deer weighing slightly more than 100 lbs, but it did the job..does an even better job on burglars,car jackers, robbers, etc...
