I normally use my 6.5x284 for hunting with 140's out to 1000 yards, the 6.5CM mostly for PRS and mid-range hunting(to 700 yards). As mentioned in my previous post, I like H4350 for the 6.5 CM. Problem is, with the high popularity of this round for the tactical sports, availability of H4350 is poor. As a back-up I developed a load using H4831sc which is readily available, and has comparable temperature in-sensitivity, accuracy, and velocity/ES. The only aspect to keep in mind about H4831sc is that it is at 100% case capacity for the load shown. It does however match the POI of H4350 to beyond 1000 yards. Bullet shown is a Hornady 143 ELD-X, but I have gotten comparable results with other 140's.
Attachment : 200 Yard POI of H4831sc(left); H4350(right). both are <.25MOA loads.
