Has anybody had a rifle barrel cryonized to incrase the accuracy. I had a .338 that seemed to wander a bit when I shot it. I figured that it was mostly due to me being a big wimp and flinching when I pull the trigger. I tried to alleviate the problem as well as I could and think I got the gun pretty steady while shooting it, although I did not have it locked in a vice while shooting it, but I still saw some wandering. One of the guys I used to work with swears he had the exact same problem with a 7 mm. and spent a ton of money on custom this and that for his gun. Nothing worked unti he got a $50 "Cryo dip" and after that his rifle was a tack driver. He explained what happens when you do it and is sold on the process. What do people here think about having it done?
