Good thinking. Blue Dot is one of the top performers in .38 Special, .357 magnum, and 9X19. Should do very well in many applications.

Only reason I'm not using Blue Dot now is that 8 lb. keg of Unique I picked up a few years ago. Another fine performer in .38 Special. Moderate range ammo, 158 cast SWC and 4.5 grains Unique. Old standby load 5.0 grains. For +P load bump it to 5.4 grains (I only use that in steel-frame K-frame or larger revolvers).

A little quick math shows me that 8 lbs. of Unique will provide me with about 11,000 rounds of .38 Special. Pretty economical!
