Just for everyone's reference, here's what Dave had to say about his cases over at Rocky Mountain, haven't written Magtech yet.
Just out of curiousity, is my impression that one could dispense with cushion wads with these accurate? Somewhere in my research I thought I read of a load stack that goes, powder, two card wads, shot, card wad. Would leave some space at the end, no doubt, but heck a Que-tip will let me seal it. The less components I can get a good load with, the better, no?
Here's Dave:
"The cases I manufacture have the gauge bore dia as an inside dia on the case. this allows standard gauge wad combinations to be used, they are made to use the standard 209 shot shell primer, and can be loaded with any safe published load data as well as black powder loadings.and I do make cases for gauge rifle loadings as well.
The cases work best with single and double barreled shot guns . A magazine type fire arm will in most instances, require a shorter case due to the magazine cut off like a folded crimp plastic or paper case would be. This requires a special dia of the case mouth due to the taper of the chamber. The cases are muck heavier in weight so do not function well with Autos. hope this helps, Dave Casey"
