I got some Lightning cleaned and polished 45 acp brass from Grafs the other day and when I went to use it it was shiny but mixed. There was small pistol primer brass Large pistol military and crimped and some foreign brass that the LP primers would not seat all the way in. I ended up hand sorting and throwing over 1/2 away. Unfortunatly I started by dumping it in my own cleaned and polished brass and I am still occasionally running into a sp primer that ties up the progressive press.
