I used the Hornady TAPs for my SHTF round in my CAR15/HBAR. They have multiple choices on bullet gr. also. have not checked on availability lately.
OH HECK! I forgot all about those damn zombie poodles, I heard they walk around chanting, ANKLES! ANKLES!Yup...that 'heavy' .223 round will be just perfect if we're invaded by poodles.
