I've been using home made dippers since 1973,checking charge weights occasionally to assure accuracy. If your technique is consistent,your powder charges will be. A loading block is essential. Check all cases with a flashlight before bullet seating. I have a chart for all my dippers and the powder(s) used.
For my .45 Colt loads,I have a .380 AUTO case dipper. It throws 6.0 grains of Alliant Red Dot,a classic load for the last 80+ years. I've been loading the 230 grain LaserCast RN,because my fixed sight SAA shoots it right to the sights at 65 yards. A little high closer in,but a very easy shooting,accurate load.
