My local Murdochs has a 6.5 CM and 6.5 PRC M18 in stock and this is a lot of rifle for the money at only $500. It checks many of the boxes for me and if Mauser offered the M18 in stainless steel I'd probably buy three. There's so much to like about the M18. Great action, three-position safety with a bolt lock, easy bolt lift, 60 degree bolt throw, great stock that feels high quality, good barrel profile, hammer forged barrel, excellent adjustable trigger, and a good quality double stack magazine. I only have four minor issues with the M18. The muzzle isn't threaded (can be corrected), the rifle is CrMo (Cerakote?), the magazine release button in the stock is quirky (but could be great), and there's no adjustable comb (can be corrected). Overall I see why
@troy fairweather has recommended these rifles a number of times. I couldn't find any information on barrel twist rate on Mauser's webpage but hopefully they get it right.
I handled a Sako S20 6.5 PRC today too and it's a beauty. The stock and the barrel were a bit of a let down but it sure is a nice rifle.
