Well Fats....If you have a three inch chamber on yer scatter gun? (Hope you do
)
You get, generally, to launch a bigger payload
.
The standard 2 3/4 OO buck load is 9 pellets of approximate .33 caliber, with known good penetration, but
also poorer hit probability past 25 meters or so....Meaning, those 9 pellets striking in a one meter diameter
circle. Don't bet on hitting a beer can at that distance with "cylinder bore" choked gun. Most "riot shotguns" are cylinder bore choked. My personal preference in the same gun is modified to full choke...reach out and touch with good pattern density.
Using the above example with same length shell, but substituting #4 buckshot, you get 27 pellets of .22 caliber, with the velocity and nearly the penetration of a .22 caliber rifle....That same 1 meter pattern, has three times the density coverage. Three times the ability to strike and penetrate a vital area. My personal shotgun had a"full choke" and was loaded with 3" Mag 12 bore #4 buckshot with 41 pellets. Meaning it would shoot a 1 meter pattern out to 40 meters. Of course, in closer, a much tighter pattern. I never had to shoot anyone with it, I always thought/knew, if I did? They would have a zero chance of survival, with in 40 meters.
00 buckshot is for Bears, Boars and the like.....where deeper penetration is necessary, IMHO.
I have witnessed one "murdering bastard" shot with #4 buckshot...he was struck in the upper back at a distance of 30 meters +/-....he was hit by 11 pellets, knocked down and was DRT in thirty seconds.
DRT=Dead Right There
On the Zombie thingy....Why can't you shoot the critters with a .22 rimfire?
I have never viewed one zombie movie, where the .22 was used.
It's a credibility issue in my opinion....
Should I ever have the opportunity to meet ya?
I got a little Ruger 10/22, I reworked....with a bunch of 30 rd mags...
And no, it ain't full auto....it don't need to be
