Either way.....you're bleeding. Except with the 2" gash.......you're bleeding 2X as much. The body cavity os NOT going to stop the blood from leaving the cut vessels......and that deer's gonna bleed out twice as fast.
No way!! Lets not forget when you have 2 holes your cutting much more then your 2" gash is with one hole. Have you ever tracked a high lung hit with one hole? Have you ever tracked a high lung hit with 2 holes? The 2 holer might save your ass in getting that deer because its got a bottom hole! I've seen it too many times not to believe it through out the years. One holers can be a bitch with high hits.
