EdCGNM,
How light are your light loads? Sometimes an extra tenth of a grain or two will raise pressures enough to make the powder burn more cleanly.
If you're loading for bullseye, be aware that you might be pursuing cleanliness at the expense of accuracy. Tight crimps, for instance, can deform the bullet enough to open groups on the long line. I suspect that magnum primers wouldn't help either since I've never heard of any other bullseye shooters using them.
