“The GOLDEN RULE of reloading is to always to begin at the recommended START load, which is between -10% below the MAXIMUM load for most Rifle calibers and up to 15% below for certain handgun calibers.”
“Yellow-/brown-/orange-ish fumes and/or powdery deposits, on the powder or on the inside of the container/s.A Strong Acidic smell that takes breath away (not to be confused with the normal solvent smell.)Any rusting of metal objects, in contact or close to the powder.”
“Whenever, it is possible to measure a parameter accurately, it is a huge advantage to know/conclude what is happening. It will immediately tell you whether the combination is in-line with the published reloading data or not. The availability of affordable and accurate chronometers has put this measuring ability within reach of most reloaders today.”
