I've personally had 5 and loaded for 2 others- All were acceptable, several fantastic. The 6.5 Creedmoor Traverse had the tightest shooting barrel I've yet to own.
My 300wsm has always shot well. It’s been very consistent at a 3/4moa gun out to 800 with 180gr accubonds. It also shot the 200eldx well just haven’t shot them enough. I have around 350-400 rounds through it so far and love it.
Mr mesa 300 prc shot 1.5” groups for the twelve rounds I shot with Hornady match ammo. It fed so bad I quit there and it’s at the gun shop for sale. My dad’s ridgeline in 6.5 prc fed awful but was really accurate. He could only use it as a single shot. He traded on a seekins which he hasn’t shot much yet. Im a lefty and sticking to mainly tikkas and brownings because I got to use to the bolt throws on them.
I don't own one myself, but my friends own 4 mesas- 3 in 300wm and 1 in 6.5Cm. 2 of the 300 and the 6.5 were great from the beginning and the last 300wm has not shot a group yet, looks more like a shotgun pattern than a group.
Ridgeline Scout in 6 ARC that’s a clover leafer and an older carbon barreled .223 that shoots just as well.
Prefer my Bergaras and by far my Tikkas but my CAs do shoot.
