I brought this subject up after sporting clays this morning at the club. Some interesting comments. Some said whatever primer was on sale is what they used, several said they followed the powder maker's recipe to the "T" and another said he used Winchester primers exclusively. No trap shooters were present which was unfortunate. But from all this I think I will just stay with whatever the recipe calls for.
Most of my doubles are old so I don't think I'll take any chances.
But, speaking of pressures. Does anybody have any info on black powder pressures? I've got a bunch of paper hulls that are just begging for some nice black powder loads.
