[QUOTE="jb1023, post: 1296456, member: 91995"] Rich, I tried to send this via PM but it says you inbox is full. So I took some measurements and thought I would post them before I spent much time looking for for a new RCBS FL mandrel. I measured the K&M pilots (6.5 and 7), RCBS 7SAUM FL mandrel, Whidden 6.5 SS FL mandrel and a piece of brass after necking down with the 7 SAUM FL die. It is now obvious as to why the K&M pilot won't fit into the necked down brass but what is not so obvious, to me, is why so much spring back? 7mm K&M neck pilot = .282 RCBS 7SAUM FL mandrel = .282 Necked down brass (inside) = .2805 6.5 K&M neck pilot = .262 Whidden 6.5 SS FL mandrel = .262 Is the case mouth not holding to .282 because I am necking down from 300 SAUM brass? If so, then should I perhaps order a .284 RCBS FL mandrel to account for the spring back? Am I the first one to have these issues? [/QUOTE]
