[QUOTE="jrock, post: 1334683, member: 78569"] I've done about everything listed in this thread other than using bushing dies. I have one for a new gun but haven't used it yet. I did find regular intervals of annealing helped but in the .243 to 7mm RM range of cases, my ES are typically around 40. My 204 is very tight on the ES in comparison. I found no difference in ES when using my Charger master or beam scale. I stopped worrying about ES for now as my downrange groups are great even if the F-1 chrony says my ES is high. Paper tells all right??? I'll keep trying new techniques and see what happens. My latest test will be using dry lube on the inside of case necks. I went shooting with a friend once and his loads had single digit ES values one day and 30+ on another day. ??? All my testing has been done on factory guns of various makes and models. [/QUOTE]
