what are we stump shootin with?and best rubber blunts??????? thanks

Blunts or Judo's work best for stump shooting, the key is finding well rotted stumps. If you shoot at fresh ones you will break a lot of arrows.

For years, I used .38 spcl cartridges on 11/32 dia. woods, and they still work great, although lighter than the steel blunt. Next are steel and Judo heads. I have used the rubber, but think the others are better.  Rubber might work just fine, give a few a try.
