Before I break out the milling machine, I though I'd check to see if anyone had found a solution to this in the past.
I need to load some 7x57 cases but have found that the pile of shiny new Sellier & Bellot brass I've sourced does not fit into either the Lee No.2 primer case holder or any of the correct RCBS, Lee or Hornady .308/.270/.243 case holders on my bench. It looks like the cases have a V-profile extraction groove (I'm sure there's a more technical name) rather than the square profile groove on the few American Federal cases I have here...and yes, I have checked I'm not trying to load rimmed cases thinking they're rimless ones .
Apparently this is also a problem with RWS cases in 7x57.
Before I machine 0.005" off the lip of both case holders, has anyone found a proprietary solution?
(time is a bit short because I'm off to Africa for a month next weekend and need to have this solved before I depart).
