At what value of X does 00 buckshot lose it's ability to penetrate to vital organs of the target (whether it be 2 legged or 4 legged)? What I'm getting at here is beyond the obvious question of pattern density at a given range, at what range does 00 buckshot, due to it's poor SD, become completely useless?

Rough calculation, a 54gr pellet of OO going 820FPS is about 80FPE. OOO weighs about 70gr per pellet, #4 buck about 21gr, and 40.5gr for #1 buck. You might try some calculations here: http://www.eskimo.com/~jbm/calculati...culations.html And I use this for reference for BC, muzzle velocities, etc: http://www.federalpremium.com/ballistics/default.aspx

We patterned our shotguns extensively, and used the ammo that patterned tightest in our guns. We consistently put 3 - 4 pellets on the target. Not necessarily in a vital zone, but on the target. The assessment was, "If you have to, you can certainly make someone keep their head down at 100 yards, and inflict some damage if they don't, with 00 buckshot." We all had guns equipped with rifle sights of some sort. Not a requirement of the course, it just worked out that way. That would not be my first choice to fight with at 100 yards, but the reality is the best gun to use in a fight is the one you have. __________________ “Life is either a daring adventure or nothing." --Helen Keller "Do not cry havoc when you should but hunt with modest warrant." --William Shakespeare Glock Certified Armorer NRA Life Member
