A 20 gauge shot cup would be used in a .62 caliber. The Wads they are talking about are made out of 100% wool felt. The wads are lubed. The general rule of thumb is if the conical has a flat base then use a wad. If it has a hollow base do not use a wad. There are some that use wads no matter what and some that do not use them at all.

If you're shooting a Knight you might want to look at some 460 grain No Excuse Conicals. They shoot real well out of my Wolverine. You could also try some maxiball. I personally have not had much luck with them in my Knight by my CVA with a wad and a maxiball does an excellent job. R.E.A.L. conicals and a wonderwad do a real good job in the accuracy department. I like the 320 grain R.E.A.L.s the best.....

The other day out of the Knight I was shooting some 270 grain Buffalo Bullet Ball-ets. They are hollow base and hollow point. I was not using a wad and the accuracy with them was excellent.

You can by wads now, from many different places. They are listed as Wad, Wonder Wads, Bore Buttons, and Buttons. You can also make your own with construction grade 100% wool felt and a 1/2 inch hollow hole punch. Pound out a couple hundred and soak them in melted more butter, then let then set up on wax paper. They work well.

Another thing on the market are the MMP sub bases. I am trying them out now on a buch of different things. So far I have seen NO improvement in accuracy and actually worse accuracy in some cases. That just means I have not found the right combination so I am doomed to keep shootingmy rifles...

Good luck...
