I am wanting to build a long range rifle in 6.5. I would be using this rifle for hunting mostly out to 700 yards, but I would also like to use it for for practice at long ranges a couple of time a month. Having said that I am looking for a 6.5 cartridge that is as close to 3000 fps as possible to retain more down range velocity, but I don't want a cartridge that is a barrel burner either. I am thinking of using either berger vld 140s or hornady a-max 140s. I would mostly best using this for deer and antelope, but could occasionally use it for elk. Would be running a 26" barrel. Thanks in advance for your help.
