is cryo treatment just a meme?

The accuracy claims are the only ones that don't seem questionable. Machining or forging will produce internal stress in a barrel, and the barrel will warp in response to temperature change. If they have a process that can relieve internal stress, it will make the barrel hold its shape through a wider range of temperatures.

Shoot some groups before and after, post targets.

You can probably increase FPS by 50, but you need to make sure you don't run out of liquid nitrogen, or the second it does, your PC will burst into flames.

I actually thought I was on /v/

so wouldnt that mean longer durability?
im just wondering if its worth the extra 80 bucks.

The effect of the treatment, if any, ought to depend on the exact steel in your barrel, and how exactly it has been treated. So unless all barrels are the same, I wouldn't count on anything being guaranteed.

How does residual stress affect thermal expansion? And if the barrels work harden in unsuitable ways, wouldn't a normalisation be more appropriate? Aren't cryo treatments there to unfuck retained austenite mostly?
