RevMike,

I've had luck with this exact delima in the past, especially with cup and core bullets.

For me, the trick is to load a wide variety of powders, with a good range of burn rates.

Also very your powder types, stick vs. spherical, and primer choices, something hot, something cold, as well.

Don't do a full workup with anything. Start with about 5 powders at minimum loads and max usable OAL, and if something shows promise, go from there.

Of course, Mono's are a totally different process.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

You cannot over estimate the unimportance of nearly everything. John Maxwell
