Ajax , I have done what you ask and I have the numbers. I did a test, Neil Winston style, counted pellets and holes at 40yds. Home made shot= 75% PE. Rem mag shot= 77.5%, same loads, ten patterns each . I have never seen home made shot that I would call round. Doesn't seem to make much difference. I haven't done anything with reclaimed, what I have seen is just too nasty to mess with, covered with oxidation.
not the Neil.
