Shotgun Ammo: Don't Be Hood-winked
I was ordering some 20 gauge ammo with 5 shot for pheasant season. (I decided to try a 20 w/#5, through the influence of Randy Wakeman.) I saw the Prairie Storms for like $19/box, waterfowl ammo prices! I have seen the full-page ads for this and other shotgun ammo and stuff and just blew it off because mostly I could quickly identify 'innovations' as gimmicks. Not full-on deceptions but more like the Simpson's episode where Malibu Stacey was offered with a new hat. Fluorescent shot wads... whatever. They are not usually WRONG in that the innovation is deleterious to the very function of the ammunition.
But this 'flitestopper' pellet is just that. It helps stop the flight of those pellets. Other companies mix shot size and type, like a few tungsten with steel. Not good.
This is all a bad idea and it's easy to understand why with just a little ballistics.
A sphere isn't a very good projectile, but is a better shape, for a given material, than any other non-conical and stabilized object. Any deviation from a 'ball' for a non-stabilized projectile will give the object a lower ballistic coefficient. In fact, a conical object, like a bullet, non-stabilized (flying sideways) is worse than a sphere.
A simple way of understanding ballistic coefficient is the idea of momentum/drag. The momentum of a certain mass of a projectile of a size and type is the same when being shot at the same speed (a lead BB s#6 or a steel BB #2 with the same M.V.). If you put that size pellet into a drop tube and then blew air up it fast enough to suspend it, you would find that any one of those pellets that is somehow 'out of round': wings, box-shaped, whatever; will need a slower flow to suspend it than a perfect spherical BB. Less wind is needed to = the weight of the pellet. So a 'non-spherical' pellet with the same momentum (mass X velocity) will have more drag.
So don't spend the $$$ on those outlandishly-priced shotgun shells. What the wads do, however, could only be determined by direct experimentation. But the shaped pellet is hogwash. It'll string-out your pattern and reduce impact velocity.
Better than ANYTHING else is get a shotgun that fits. Learn how to shoot it. Hunt in a place with abundant game by 1)paying for them or 2)by doing/supporting/paying for habitat and access. Goofy pellets will not help.
