What say you?

These first two are with the SK .005 tube at 25 yards. The shotgun bore is .733 FWIW.



These next two are at 35 and 40 yards with the Mod .020 choke.



These loads do kick! More than I thought they would for 1 1/8 oz @ 1200 fps, but then all that buffers adds in there, too.

Based on what I see I might have Briley make up another tube with .000 constriction. My Skeet tube seems tight for pointed pheasants. I have a feeling straight cylinder will be more than tight enough.
