I have a 6mm cm and a 6.5 cm, I have loaded several bullets for each. Have used Hornady 140 ELDM, 140 HBM, Nosler 140cc and Nosler RDF 140 and 105. All bullets have been pretty consistent a side from the RDF bullets. One shooting session I can shoot 1/2 minute or better, next time out I'm over 1 moa, again the other bullets do not seem to have any gremlins in them, any of you experience this issue with the RDF bullets?. Powders that have been used are H4350, RL16 and Superformance, which I use in the 6cm, excellent accuracy. I have played with the bullet seating depth with the RDF bullets, is there a magic number for OAL or are these bullets sub standard?
