I got the chance to go to the range today and burn some powder. This was my best pattern @ 40 yards with Hevi #7s through a Sumtoy .650 choke in a SBE II. Other patterns were as good, but not centered until I got the Speed Bead dialed in.
This had 338 pellets in the 10" circle, 209 between the 10" and 20" circle, for a total of 547 inside of 20". I'll take it.
Hurry up and get here turkey season.
