I am new to reloading and am using the lee powder through expanding die.. I am loading 9mm using power pistol (6g) for 115g FMJ.. I have loaded about 400 rounds this far and shot 75 with no issue but today I have noticed powder was building up in the neck of the die :-( ... I have been carefully measuring each powder charge and now I don't know how much I was losing in the die.. It was about 4g of powder built up on the dies neck.. I reread the dies instruction and it warned that the lubricant causes this issue and to clean it and keep an eye on it.. I don't know how I missed this and I feel stupid now.. What do you guys think..i think I'm gonna shoot it (carefully) cus I have been checking each round visually as well so I don't forget to charge one..
