I have tried about every product sold. I use an 40 year old Rock Chuck. Load about 2000, to 3000 total rounds a year of the following 223, 243, 25-35, 260, 270, 7mm-08, 300 Savage, 30-06 and 358 Win. For the last few years I found Dillon Case Lube to work best on the cartridges I load, and all are easy cartridge to size. One 8 oz spray bottle at 8.95 last over a year.
