This would probably be better answered in the firearms forum. But Ill bite anyway. The point blank range of a cartridge in my opinion, assuming that youve practiced at that range of course. Point blank for an -06 with 180 gr bullets and a standard 200 yard zero would be around 250 Im sure. Did I use the term "Point blank" properly? Im sure one of our ballistic gurus will quickly straighten me out. I know what I mean just may have improperly used a term to explain it.
