Dead on target Dave. As per SOP for you.
When I was shooting a lot of sporting clays, my pardner and I used to get silly grins watching these guys spinning tubes in and out. Never seemed to make much difference.
One other point - check my headspace and timing here - with new folks, I usually explain that there is a (improved cylinder/modified/full)
choke tube and (improved cylinder/modified/full)
pattern - but - depending on your load, they may
not be the same.
The first is the amount of constriction, the second the number of pellets in a 30' circle at (IIRC) 30 yards.
