Most shotguns have a smooth barrel, especially those designed for home defense. A super high-speed movie camera recorded the dark side of the screen, capturing the pin points of light as each pellet in the shot cloud went through. This equation was checked for steel shot and gives the same velocities as obtained from the SSB software using constant ballistic gelatin penetration numbers. The following also takes into consideration the minimum Pattern Pellet Count necessary in a 30 inch Patterning Circle for a clean kill. This is a phishing scam designed to take your login information. Ned S the young 87 yr old.
Shotgun Shell Ballistics & Penetration
At all ranges, whether short, say yards, or long, yards, we should each get to know what our gun can and cannot do by carefully patterning the gun. TSS 8 shot pellets per ounce. So choosing a 20 gauge gives you a narrower range of self-defense ammunition choices, with no real upside. Steel shot pellets deform little. After all, for years the theory has been just increase your shot by two full sizes over lead when you are forced to use steel, and all is well.

These "shock" or "stress" waves have been photographed and I think the Swedish Cartridge Company Norma published some of these photos in one of their bullet brochures a few years ago. We speculate that is related to the moderate shot deformation observed in the pellets recovered. Distances between muzzle and target for the 4 buckshot and unplated 1 buckshot correspond to the maximum distance at which a single shot pellet is expected to be traveling fast enough to score an incapacitating hit. I solve Newtonian formulas everyday for a living. As the brennekes hold together better, they are a more appropriate slug when deep penetration in dangerous game is required.
I will edit my post to say, "Lowry, et al. Because of aerodynamic drag, buckshot spreads radially outward at a rate that is nonlinear with the translational travel of the pellets towards the target. The total combined cross sectional area of the 16 pellets is 1. If you do not believe me remove some pellets from a quality clay cartridge they normally have the hardest lead shot not game cartridges — I wonder why? There's a lot of debate in waterfowl circles regarding which parameter is the best predictor of lethality. In all shotshell loads, number 1 buckshot produces more potentially effective wound trauma than either 00 or buck.
