I shot over 3,000 patterns looking for ultimate long range performance back in the 80s. I do not fault Dr. Jones' efforts, and I apologize if I sound high handed, but other than as a mathematical exercise, I didn't "get it" is the only way I can put it. I make no claims to being an accomplished statistician or mathematician. I did find that when comparing the effect of a variable I did get down to comparing 10 shot averages the get conclusive at the end of each trial.
I was quite satisfied with my results, but I am still rather mystified at how George Diggweed manages to do a lot of what he does, with what he uses. That guy just amazes me.
Here's a little interesting old shotgun trivia for you.....
As printed in the "History of Bullets" 1st Edition 1958...:
The increasing of the size of the shotgun, and the size of the individual pellets of shot, can be used to increase range only to a limited extent. There are several disadvantages inherent in this. Few men today shoot enough to swing a 10 1/2 pound gun. However, in the past certain arrangements have been tried for much greater increases in effective range, even to more than 100 yards. During the muzzle loading era in Britain, a kind of wire cup made by Eley retained the shot all in one cluster inside the cup for perhaps 50 or 60 yards, and then let them fly free.
Shrapnel Spherical and Elongated Shot Shells had two shell segments filled with shot and were held together by a light wire spindle. The entire assembly was loaded into a shotshell with wad end down. When fired, the device traveled intact for a distance and then the wire spindle separated from the shell segments releasing the shot. An effective range of 95 to 140 yards was claimed.
A bit later, a patented shell was used to contain the entire shot charge. The two halves of the shell did not come apart and release the shot inside until a predetermined range had been reached. This range could be varied when the shell was loaded; in theory at least, a sportsman could change the effective range of his weapon at will. The advertisers of this scheme claimed that the entire shot charge could be put in a 30" circle at 130 yards. It would seem highly unlikely that this device worked in the way that it's proponents said that it did, "
even though William Greener spoke well of the idea." Besides, who can hit any form of shotgun target at 130 yards ?
The Modern Shotgun has reached an advanced state of development. Ammunition for it is extremely reliable. It's efficient use, however,
requires agility, coordination and practice.Because of the drastically reduced bag limits today, few hunters, if any, can hope to learn to use a heavy ten bore Magnum on ducks and still fire well with a seven pound twelve bore on upland game. The trend is towards smaller bores and reasonable amounts of medium sized shot.
Individual skill is far more important than extra gun performance. Any shotgun usually has a best load for each size of shot.
The man who finds out what this is and sticks to it with plenty of practice will be hard to beat.
