Winchester. Very consistent.
I single stage all my brass to bell mouth and primer at the same time. Really helps to catch the bad brass. Then over to the Progressive Press. I can tell when bell mouthing each piece of brass which is hard or soft. The ones that bulge to one side are usually very hard and get tossed, possibly just over worked (fired and reloaded more than a few times).
I've tested both hard and soft brass and very similar in fps on the chrono. Winchester for me just seems to be right in the middle. Verse's softer brass, FC, Speer, Blazer, etc... and the harder brass RP, HRGT, S&B, Geco, etc... Using 8.6 HS6, Fed Primers, Everglades 115 jhp at 1512 fps.
But I'll load them all, as long as they do not bulge during bell mouthing and fit my gauge. And they all get gauged. If I had to pick 15k pieces of brass, it would be Winchester.
