Bought a set of Redding dies awhile back to use for my 6.5 PRC. Looked online, and it said that a #4 RCBS shell holder was correct, already had one so I thought I was good. Recently, a buddy bought a PRC and a set of RCBS dies, and the box said use a #38 shell holder. Looking on the RCBS chart, it doesn't have the 6.5 listed, but the 300RCM says number 4. Anyone else noticed this?
