Your primer problems may be an adjustment problem check your loaders manual.

Titegroup, Bullseye use the powder you have the best results with.

I have a chronograph and rarely use it except to verify power factor.

Are you using a progressive press, and is every bullet coming out at the same OAL? My real concern is the variance and how I can reduce it, or is it acceptable?

SSG,

I'm using a Lee Load Master progressive press. There will be small variances in OAL with any press system. Check a box of factory loaded ammo sometime. A difference of a couple of thousandths won't make any difference I doubt a difference of a couple of hundredths will cause problems. Now, tenths - - - that's a whole 'nother story.
