What distinguishes "military grade" from any other shotgun shell?
We are blessed with such a wide selection of quality buckshot loads.
I don't have a dedicated defense shotgun anymore, but what I do have was built up over several years and includes: buckshot...Winchester Ranger #OO buck, Remington #4 buck, Remington #00 buck, and more recently Remington Managed Recoil #00 buck; slugs...Brenneke K.O. 2 3/4" 1 oz, Brenneke Tactical Reduced Recoil 2 3/4" 1 oz, and a few Federal Truball Reduced Recoil 2 3/4" 1 oz...
being a 'hunting' shotgun I also keep around various Federal #7 1/2 & #8 lead birdshot, Remington 3" Nitro Turkey #5, Kent 3" 'Multi Purpose' #2 & #BB steel shot loads...
if I had to use it for defensive work I would start with the reduced recoil #00 buckshot, regular #00 buckshot, and then #4 buckshot; the slugs were bought to use for deer hunting if my primary rifle ever had a failure...
I'll be getting my Mossberg M500 back soon. I'll load it with OOO buckshot.
So you can have less wounding potential and more over-penetration. Good call.
Less wounding potential? With 8 .36cal projectiles @1350 FPS?
I ended up getting some Hornady TAP low velocity 00 Buckshots, Federal low recoil H132 00 buckshots and some Winchester #1 Buckshots XB121.
How is it they can fit 9 - 115gr bullets is a 12guage case. Man that's a lot of cramming.
Calculate the amount of shot surface area that is in contact with flesh as it travels through the target. That's what causes damage. The contact area times the penetration depth.
8 .36 cal balls provide 1.62 square inches of area contacting (damaging) flesh.
16 .30 cal balls (#1 Buck) provide 2.26 si. That's 28% more area (if I did the math right) damaging tissue as it passes through the target. One third more pellet area, 32%, over 00 Buck.
00 Buck typically penetrates 20-23 inches in ballistic gel. 000 Buck would be much worse (more penetration than 00B - bad). Any penetration beyond the target is wasted and in fact increases your liability by threatening other objects/people beyond your intended target. #1B hits the FBI recommended (>12" - <17") sweet spot at about 14.5-15". The added recoil of 00/000B doesn't aid in quick followup shots either (in case of multiple a/o armored targets).
#4B sometimes makes 12" and sometimes does not while providing only a marginal area improvement of 7-8% over #1B. Any load that does not consistently provide enough penetration should not be considered for serious defensive use.
Good choices. If you find your gun has preference in those loads, stick to it and it will do the job just fine.
It is eight .36caliber pellets in the 12ga case. I am thinking about changing over to the No. 1 buck load. This thread has an impressive video showing the No. 1 buck in action.
