I saw these for sale on eBay during the winter so I thought I would give them a try.
They are a sabot type ball patch....kinda of neat.

The ball sits in a cup, spru up...the bottom is a cup.

Beign as it was a rainy day, I set up inside my Range Shack and give set the panel at 25 yds just to see where they were hitting first.
I'm using .440 ball with .45 poly patch at 25 yds with 60 gr of Pyrodex.
The 1st shot

The 2nd (thru the same hole)

Then the rain really started to come down, so I called it a day...
So overall I'm impressed with these Poly Patches. They load a little looser that the cloth patch, but I assume the cup must seal up the gases better. At least the accuracy seems to be there, at least better than I was getting with the patch/ball.
Still having a hard time sighting...hard to see the target...or hard to see the rear sight...one or the other :)
