Dean i believe there has been a lot of study by among others ,Tom Roster, about speed and lead. The conclusion being that the reduction is so small as to be useless. It may give some a physiological boost, causing them to have confidence in their abilities but is of no practical use.

Well that’s another reason I’m glad I don’t use it.

I also have done a lot of pattern testing over the last 10 to 15 years with different shot sizes and speeds. What i found out was lighter and slower (1145 to 1200 fps )loads shot the best and most even patterns also i found 6 s shot the best patterns but by only a couple percentage points in each test.

My understanding of shotgun ballistics is that the terminal speed at 40 yards is almost the same, regardless of what speed the shot started at.
I read this somewhere, maybe Brister. Don't remember. But the point is, if the shot is traveling relatively the same speed at the target from an 1100 fps load, as it would from a 1300 something fps load, why suffer the additional abuse? |

1,33 minus 1,100 equals 200 fps
There are 5,280 feet in a mile, A bird or clay target traveling at 40 mph covers 1.46 fps according to my calculations. Then you need to figure in angle of flight and trajectory. I think there really is a difference in the lead the shooter should allow. .

Ballistically spheres do not do well and right around the speed of sound they especially do not work well. A #4 lead pellet starting at 1325 feet/sec. gets to 40 yards in approximately .126 sec. with a retained velocity of about 749 feet a second. That same pellet starting at 1200 feet/sec. gets to 40 yards in about .135 seconds with a retained velocity of about 708 feet/sec.. So at the start there is about 125 feet/sec. difference but it has dwindled to less than half that at 40 yards. The .01 sec time difference would get you about .9 feet less lead on a 60 mph bird. To my mind the extra abuse of the higher velocity doesn't really buy you much.

Yes. I always put the extra .9 feet of lead into consideration on my 35" pattern at 40 yds
