Cleaning the base after sizing/lubing

[Petrol & Powder]

So what do you guys think about just carefully removing the bevel on the mold?

Well, if you really liked that mold; maybe.
It can certainly be done but it would be simpler to just get the mold you wanted rather than machining the bevel out of that one.

or tumble lube and use a push-through sizing die like Lee's.
