After removing too much primer crimp brass from my last batch of Lake City, I thought I would try it again.. But this time I wanted to ask your opinions regarding HOW MUCH brass to remove? I am using an RCBS Case Prep station and the Lyman Primer Pocket Reamer shown below.
But I'm not sure how much material to remove? A thin strip? a THICK strip? I know the easy answer is "as much as you need", but I'd like a little guidance. Do I just ream it for a quick couple turns, or do I bear down on it until it is reamed out as far as the tool will reach?
In the 2nd picture, I colored the primer pocket of my case blue, so you can see where the pocket is being cut.. Once on the rim, where it bevels the edge where you would expect the crimp to be.. But farther into the pocket is another cut line as well (red arrow).. Any thoughts?
last thing, using this Lyman Reamer is difficult, because I have to gorilla grip the case and put quite a bit of down-pressure to get the bit to bite.. is there an easier tool?
