I also have a 6.5 CM Rock Creek 26" barrel made by Josh at PVA but this one hates the RDF 140gr, tested with H4350 and IMR4451 from touching the lands thru 0.07" and never got consistency with it. On the contrary it makes one rag hole with the ELD-M 140 gr with both powders at 0.020 off the lands in three different nodes.
