The ATX rifles can definitely be accurate. I shot an f-class match with mine a few weeks ago and shot a 593-39x from a bipod. That's 39/60 rounds into 1/2 moa at 600 yards. The lost points were wind and my fault. That was with a Bartlien in 6bra spun up by SPR but if anyone wonders about the accuracy limits of the action/chassis, in my experience they are exceptional. That barrel shoots 5 shot groups in the .2-.3 range. My factory 6.5 barrel shoots under 1/2moa with almost no load development, 143 eldx and 41.5 h4350. First load I tried, never moved seating depth, just a quick work up to 41.5gr. Definitely a good barrel.
I think the ATX is a steal at $4k brand new.... Shit, a defiance bare action is $1900 now. Super versatile rifle. Carbon barrel and you can be hunting at around 13lbs, shoot PRS out of the box, I shoot f-class with it too, 223 conversions available, batch of spare bolts just got released hopefully that becomes normal, I grabbed one to do a magnum conversion. Accessories are expensive but honestly not that much more than a lot of other brands and everything just fits and works, no having to mess with stuff to "make it work".
I hate sounding like a fan boy but they're just good rifles. If you're thinking about buying one just do it.
