To Pattern a Smoothbore

It was time to discover just how much and where 7 1/2 shot hits at a given distance without over much wind or alien intervention.

Three pieces of cardboard. Two out of a Cylinder choked tube and one more out of a Modified choked tube. 16 gauge SxS for those that care about proper barrel orientation.

Referring to Cylinder (which is what I was really interested in) as I am prone to have .005 (SK) in that right barrel. Ya can’t write that if the barrels are stacked.

So–at 20 yards, the pattern is 30 inches but for a few fliers.

At 30 yards, the pattern is 36 inches but for a few fliers.

Modified it is around 24 inches.

This will do just nicely and I feel not need to have additional constriction in the right.
