I loaded 300 rds of 40 S&W. 2 boxes of 155 gn fp and 4 boxes of 165gn fp, recleaned 4 boxes that I cleaned about 5 years ago and had some dark spots like corrosion and primed them all. My son wants to see what it takes to load so tomorrow, if he shows, I will have him set a powder load and check it, I think he thinks it is easy, but he will find out how time consuming it really is.
