I only have one 6.5 CM and that's in a Savage LRP.
Reason #1: With Hornady 140 ELDMs it consistently groups between 2.25"-2.5" at 587 yards.
Reason #2: My Bergara HMR PRO 6 CM groups on the .2s @ 100 yards with Hornady 108gr ELDMs at 2990-3000 fps @ 450 ft elevation.
Reason #3: My 22 CM with 80gr ELDMs with the first load I've tried is grouping .750" ish at 287 yards.
Nothing the matter with the 6.5 CM but because it's on a Target action I've decided to re-barrel it to a 284 win. I plan on sigle feeding as this will be my dedicated 1200 yard+ rig for ringing steel. Once completed I'll figure out where it hits 1300 fps ish and then start to figure out BC changes and get to a mile. I know I can just calculate for the 1740 yards but with what is hopefully a very precise rig I want to try to understand, from my own experience, what happens at and after trans sonic flight with a particular bullet. I know it's been extensively written about and I'll use some of that knowledge but I want to discover for myself and then see how other calibers and bullet combinations react. It's science so it's not just having fun and burning 100 bills! Right?...
