Ok, now I'm really curious what speeds you are getting and what bullet you are running in the 6BR. Most guys that I've spoke with are around 2900 FPS with 105s or 108s with a G1 BC around 0.535.
I can easily hit 2850 FPS with the 88 ELD with a G1 BC of .545, and with fire formed cases I'm comfortable with 2900 FPS, with less recoil than the 6BR. So it seems as though I'm getting about the same trajectory, but maybe I'm missing something.
I get it how the 6BR is a dream for accuracy, but how much better can the ballistics be than what I'm getting with my 223?
My current rifle does not have a tight neck, but I'm seriously considering a new barrel with a tight neck so I can neck turn and really dial my 223 in.
I have things set up where I quickly neck turn brass in lots of 2-3000 anyway, so it wouldn't be a big deal to add my 223 to the mix.
And here's the thing.... I think of PRS as a priority game... where I have to manage the time it takes to the odds of getting a hit. On that basis I tend to rush the long shots and get back inside 850 yards where I'm confident I will make a hit. So to me, it seems that sacrificing 1200 yard performance is of little consequence... unless you are in serious contention to win the match. Which I'm not.
