I just bought a case of One Shot. I do 1000's of cases in a month. I use One Shot exclusively. I did over 2000 223 cases and not 1 stuck case. I did 700 308 cases not 1 stuck case. I don't get it. That don't include all the 224 Val, 6.5 Grendel, 6.5 Creedmoor and all the others I do. Oh well. It works for me and I don't get stuck cases. Whatever works. Gotta go with it.
