I'm like bigcountry in that I don't spend as much time and attention any more to working up a load. I don't have the desire and time just doesn't permit it.

I start 5 or 10 percent below max and work up in 1 grain increments. Every charge is weighed on a beam scale. When I approach max I might go to .5 grain increments, just depends on how I feel that day. I still pay attention to details like cartridge concentricity, case neck wall thicknessand so forth and I think doing so makes it fairly easy to find agood load as long as you're using a bullet known to be accurate.
