45-90

[Lumpy Grits]

I use rifle primers and have yet to try the wad in the primer cup, with a pistol primer.
I too wasn't fully convinced about the under-powder wad deal, until I loaded up a bunch of ammo with and w/o the 'wad. I then tested them from winter to fall with the 'E' 2F. The target doesn't lie and I could see much less V and a far more rounded grouping with the .40 cal dia piece of white coffee filter paper 'wad'.
Each gun has it's own preferences. Both of my Shilohs prefer the paper under powder wad.
Just part of the fun in play'n with those old rounds and roll'n your own.
