I am considering stepping up from my Rock Chucker I have some questions. I am obsessive about prepping brass, I spend 3-4 times as long prepping brass as I do loading it. I load every round as if I was using it in a bench rest match. and I weigh every single powder charge. Would I really benefit from a progressive? If so a 550 or a 650 Dillon? can they, or the "Lock and load" load Hornet and fireball brass? I am a varmint hunter and need lots of small caliber rounds. I shoot Hornet, K-hornet 19calhoon, Fireball, 204, 222. I am also worried about accurate powder measuring. Any tips or thoughts would be greatly appreciated.
