As I am a new reloader and may be taking this to extremes by being anal....I tinkered and tinkered with my Dillon to get 4.7 grains of powder....Test it about five times then start reloading...Pull out a cartride (9mm) off the shell plate dump the powder on a (Dillon Digital Terminator) scale and it reads 4.6 or 4.8...Fiddle some more get it to 4.7...OK then I get the bright idea to weigh the finished product...MISTAKE...practically no two rounds are the same 181.1 or 183 or 180.4....Then for sh*ts and giggles I weigh the bullets (115 Grain FMJ RN) hell they are not even constastant, either is the brass...No wonder the finished products are not the same as the one before..Hell, should I have gone for a single press if I am going to worry about these wieghts or is the amounts to minute as not to worry about it...
