I shoot light loads for bullseye, and get pretty poor performance out of the powder as a result. With TiteGroup the chamber fouled really badly; with W231 fouling is moderate but a good amount of powder is ejected unburned. I'm just starting a pound of Clays to see what it's like but don't have results yet. I know that the powder is probably the biggest factor, but I did wonder if changing to a magnum primer might create better ignition? The slightly raised pressures shouldn't be a problem, I would think.
Has anyone here ever experimented to see if there's a difference in the amount of fouling or powder ignition with light loads with regular vs. magnum primers? If so, it would save me the effort.
Thanks!
