I have the opportunity to pick up a 6x hart barrel in 26" in mint condition and excellent price complete with dies. I just want to know if 6x is a good round and if anyone has experience with them and recommends that round. If the experience is good, what loads were being used and what kind of performance were you getting. Drop at 1000 yard, fps, bc, etc... that type of stuff. Any advise will work and would be much appreciated.
