One of the unbreakable rules of reloading, ONLY ONE POWDER ON THE BENCH AT A TIME! Guess which DUMB A#$ had two tonight. Poured about 500 gr of 4227 into a can of H S 6 and knew it right away when I looked at the 4227 can. Took it out back and watched a long string of powder go up in smoke.$28.00 worth of smoke.
That's what 10 experimental rounds cost me tonight because I broke an unbreakable rule.
