I have a Howa Alpine Mountain Rifle is 6.5 Creedmoor and a Browning Hell's Canyon Speed in 7MM Magnum. I don't know if either of those qualify as your subjective "high end"; but, to some they do. Let me know if either "might" interest you and we can pm specifics. I didn't send this via a pm because, well, then the whole world wouldn't see it.
I have a tikka superlite 6.5 cm lefty and a copper m92 backcountry 7mm rem mag lefty. Both more accurate than I am. One is for deer sized game and one is for everything else. Many said 6.5 was enough for most of my “everything else,” but I wanted another rifle.
EDIT, did t realize this was a WTB. My mistake. Free bump I guess.
