Ok I got the round seating plug from RCBS today and tried reloading some nosler 158gr HP's.
It worked alot better than the SWC plug
but it still changed the shape of the lead tip.
It starts off as a cone shape and when I seat it it ends up a bowl shape.
Its hard to get it to seat exactly the same every time.
So what am I doing wrong now??
BTW. RCBS has VERY good customer service, they sent me all new plugs and lock rings and would not take $ for them.
