I load both pistol and shotguns so I’ve been looking through the half dozen or so manuals I have and something keeps puzzling me. A lot of powders are listed as good for both shotgun and handgun cartridges. That makes sense with similar pressures and velocities. I like the dual use powders for that reason.
The question really is why do we see loads for both shotshell and pistol with Unique and HS-6 for example but no shotgun loads for Power Pistol or HP 38 and no pistol loads for HS-7?
The burn rates aren’t all that different so is it a matter of volume in the case or just marketing differences?
