Remington 410 wad difference?

I see Remington 410 wads stitched and 410SC wads. What's the difference and does it make a difference in shooting skeet?

 

Often, a stitched wad will not work well in some loading machines (MEC).

 

The "stitched" wads are great when used in a P/W or a Spolar. The stitching keeps the wad petals from folding in. They are not good in a MEC loader.

 

What is the problem or what do I need to look for in using "stitched wads in a Mec Grabber reloader)?

 

I don't know about the Grabber but there is limited space to slide the stitched wad up onto the shot drop tube on the 9000G.

 

Thanks very much for the information.

 

When you use the stitched wads on a MEC you have to push the wad up onto the drop tube and break one of the stitches. The wad will then stay on the drop tube. It is a little slower than open wads.
