Here's the results.

About a 6 inch group.

Not as good as the Remington in this rifle, but remember that rifled shotgun barrels have preferences for certain brands of shells.

This one seems to like the Remingtons better.

Let's try these shells through the smooth bore.

Looks like about an 8 inch group (these are marked with triangles), almost as good as the rifled barrel.

Who would have thunk it?

I took this picture to remind us of an important fact.

A bead-only sight, which is very common on shotgun barrels, is not conducive to precision marksmanship.

The bead covers a lot of target at 50 yards.

I honestly believe I could have shrunk these groups in the smooth bore, if I had rifle sights or a scope.

We picked up some of the sabots from the Remington shells.

Here they are.

They were found at about 25 yards from the gun.

We recovered some of the wads from the Quik-Shok shells.

They were actually found behind the target, indicating that they stayed on the slugs all the way to the target at 50 yards.
