I have been wanting to have a custom target rifle built for medium (300) to longe range for me (800) yard targets and maybe take an occasional whitetail or coyote at 500 yards. I was thinking about a 6BR cause I have read they are very accurate. I would love some input from someone who might have one or has experience with them. I have enough 7mm calibers to hunt with and just want a mainly target rifle that dont have a big appetite for powder but still has enough energy at say 400 to 500 yards to harvest a whitetail if I so desired. I have a good 22.250 AI but I dont see it harvesting deer at 500 yards unless I head shoot em. Thanks in advance!
