Definitely wad technology plays a roll.
Shot consistency as well.

You don’t see the so called “billiard ball effect” to any real degree in the images.


Out there doing it best I can.

I found it interesting, as mentioned in the video, that the pellets, especially the steel, did not bang into each other and cause pattern destruction as I have heard happens. The load of tungsten and steel separating with the tungsten falling behind was interesting as well. I assume the tungsten was loaded behind the steel in the cartridge. It would be interesting to see other types of loads, like various "spreader" wad loads, some turkey loads, and how different types of choke affect the shot column.

AGS summarized it very well. And, the conditions he mentions (I think) are for 90 degree crossers (as he calls pass shooting). This is only a small fraction of total shots fired at game birds. Some are straightaway, some are dead incomers, many are quartering. All these would be affected even less than a true crosser by long shot strings.

Here's the follow-up video!

Some interesting food for thought.

Okay, now we need Brister's wife pulling that board with the duck on it and the $300,000. camera filming the pellets making the pattern on the paper duck. Just for fun though because the shot string is unimportant.

The owner of Patternmaster must've run over his dog...Gil

I wonder too, why Patternmaster was on the hit list. I also thought about the one specialty choke I've bought that does not perform either.

I wonder why the swing velocity of the shotgun (shotgun "lead") wasn't entered in the calculation. There are three, not simply the two movements (speed of shot towards duck and duck's speed), in play in a crossing shot. The gun barrel is in motion to lead the duck and the crossing momentum of the shot column would be losing velocity (as does the shot's muzzle velocity). Perhaps the calculation of the shot column's sideway's velocity is minor by the time it arrives at the 40 yard duck. (Once an object is in motion it will continue to stay in motion until slowed and stopped by gravity and friction.) Gil

When I first had a shotgun barrel threaded for choke tubes I only owned one shotgun, but I had three barrels for it, a 26" IC, a 28" M and a 30" F. it was a Remington 1100 my Dad gave me for my 16th birthday. I had shot many patterns with those barrels and was accustomed to what I thought a typical shot pattern looked like, with it's very "hot core". I had the 30" F barrel threaded and bought a set of CompNChoke tubes. I commenced to shoot more patterns to see if there was any difference, on paper, saving and labeling the patterns. I was astounded to actually see a difference I could quantify. Simply put, there was less of the total percentage of pellets in the hot core and more in the outer 10" "ring" of the pattern. I immediately realized that this was a good thing for clay target shooters, especially, as it decreased the chances of a clay slipping through the pattern in the periphery.

I took the rolled up patterns to the office of the owner of CompNChoke and showed them to him. He was surprised I had gone to the trouble of patterning them that thoroughly, but smiled when I showed him evidence of what I had seen. He may have been correct, or he may have been wrong in what he said next, I don't know. But, he said that was the result of precision machining in the choke internals, and said that was something that was sorely lacking in the Remington's fixed choke barrels. Obviously there are other choke tube companies, and fixed choke barrels, that are choked with precision and care, and will deliver the most uniformly distributed patterns possible, but I'll go to my grave knowing the difference I saw between those chokes and MY old fixed choke barrels.
