Quoted:
Larry Vickers says on Tactical Arms that Buckshot is a poor choice because it spreads out too much at distance.
Has he not heard of Flite Control? You can push the distance at which you can get hits on an human torso out pretty far with it, but the problem becomes that you lose a whole lot of penetration once you get out that far. Spheroids do not have good aerodynamics and the same properties make poor penetration after impact.
That's why you switch to slug. The slug band is typically determined at 25 yards plus in pretty much every class I've ever taken, to offset both the widened pattern and loss of velocity from buck.
LAV's statement doesn't make a lot of sense, but that may be because I didn't see what he actually said or maybe the context.
Most tactical shotguns are Cyl choke. Why shouldn't they be Modified and would that solve the pattern issue?
Because a lot of defensive shotgun rounds are made with a C or possibly IC choke in mind, and developed under the assumption that that is what they will be used in.
The solution to the pattern issue is Flite Control or possibly a Vang rework.
Also is there a big difference in useability between 2 3/4 shells and 3" shells with buckshot? Seems recoil would be much more managable with 2 3/4.
3" rounds give you more recoil for very little return.
