I live in CA so only 10 round mags for me, anyway I want to buy a diff cal bbl other than the 5.56. I cannot decide which of the 3 is most accurate and affordable down the line. I do reload but not for any of the 3 as I do not own other rifles in the 6.5, 6.8, or 7.62. What do you guys prefer and why. I would probably hunt mule deer at less than 150 yards, I only have access to a 100yd range locally (free for me LE although I am not an LEO, I am an ACO)
