Just a side note on Bullseye and 700X. I use both for .38 Spc and have loaded up and fired off 2 or 3 thousand a year since the late 80's.

I like both, I will hand weigh every charge of 700x. I've noticed when I run them through through a Chronograph, they have a significantly wider velocity spread than rounds loaded with Bullseye. I don't hand weigh Bullseye though, I use either a Hornady powder thrower or a vintage 1980's RCBS uniflow.

food for thought.
