Using Fed or Cheddite data they are both straight walled hulls and they have a large number of 7/8 oz low pressure loads i.e., 5000-6700 psi, listed. I've started using CB6100 wads.

Aaron, no 7/8 ounce load with Green Dot (close to published load) ever blew up a good 12 gauge gun. Green Dot is a little slow for low velocity 7/8 load but it should be fine in warm weather.
