I'm starting to put stuff together for my next rifle which is going to be either 6.5Creed or 260 Rem and was wondering if anyone has tried 2000MR with the 140Amax 142SMK or 139 Lapuas. H4350 is nowhere to be found and I have a pretty good supply of 2000MR so if the 2000MR works with the 6.5/260 loads it'll be one less thing to worry about. I've had excellent results with 2000MR and 168-178 bullets in a 308 but I'm thinking maybe 2000MR will be a little too fast for the 140grain bullets. I've already picked up a lb of RL17 to try it out also. Thnx
