A question on how often you confirm the charges you are throwing are within tolerances? I have read several different intervals from every 5th throw up to 25-30. Being new at this I am probably more careful than seasoned reloaders. I use a bench mounted Lee and throw 4 in the brass and the next in the pan to confirm. I assume after time when you can trust the equipment more that number will change. Just newbie trying to get smart.
