I have been working on a project acquiring parts to build a 6mm Bolt gun. I have a HS Precision stock, CDI bottom metal, Savage action trued and timed and a Benchmark 6mm blank to be finished at 26". I was originally thinking of having it chambered for 6mm Super LR ( Robert Whitely's creation ) but was talked into maybe going with a 6Creedmoor. I can find brass and dies but load data is spotty. How popular is this round? I would prefer to stay away from the 243 just because it's so mainstream. I realize what a great cartridge it is I just want something different. Thanks much for any and all help
