Re: 6.5 -284 Ballistics??
I answer to a few of the questions. My Cooper 520 weighs 10.5 pounds fully loaded with bipod. The .78" fluted barrel is a great weight for my mix of hunting
It was a gift from my wife a few years ago from BOTW which was a nice surprise. Everything else I own has been put together by myself. It was supplied with loads that were built with JLK's at 2965FPS. First time at 500 yards it put 5 shots into 2" circle. I have since used my reloads using mostly 140 Bergers that perform as well, but I have shot about half a dozen deer and antelope between 500 and 1000 yards, and acoulple of coyotes out to just shy of 1100 yards. The jLK terminal performance on game appears identicle to the Bergers. The JLK's I have are 142" grains and have a BC of .640 compared to .612 with the Bergers. To use the same dope with the Bergers I set my computer velocity at 25FPS higher. I bought 200 of these from BOTW shortly after I got the rifle. I'm not sure they are a standard catalog item from JLK/Swampy. The rifle still shoots under 2" at 500 yards using either JLK's or Bergers. I have about 500 rounds down the tube. Art
