For whatever reason the chop saw I got did not have the power to cleanly cut the cases. It messed a bunch of them up. Went to Harbor Freight today, but their current mini chop saw is the same as the one I picked up from Amazon only with a different label. For $10 more I decided to try a 6 inch cut off saw. As brass is non sparking, sparks should not be an issue but I will start outside just to be safe. This is what I got. Will let everyone know how it works.
