Love that Range-Time

M/L propellants are very forgiving and I'd say to stick to 5- Grn. increments (by volume). There is always a Min - Optimum - Max. Obviously you want the optimum and seriously doubt that it is going to the 120gns. I could guess but it really takes "your" range-time to determine this. Perhaps the folks at BH-209 can give you some suggestions. I know I have seen optimum loads published for BP and Pyrodex. .....

Be Safe !!!
'Fundamental truths' are easy to recognize because they are verified daily through simple observation and thus, require no testing.
