WATER IN BORE:
Tests have shown that the worst thing for accuracy is water in the bore.
Avoid this when cooling barrels with wet towels.

Eric, I am shooting Stolle Panda's and Hall M benchrest rifles that were turned into varmint rifles. Then went to other factory and custom rifles.
You got some very bad information from somewhere, reading on the internet is often real bad. My system was developed by Rockwell's #1 engineer on the B-1 bomber project. Steel has to get to 850* before water would warp the barrel, and barrel heat from a bolt gun shooting is no where near that amount.
Eric, you need to stop repeating that fake news, it is ALL wrong!
Remember, after water is ran down the bore, 4 TIGHT patches are ran down the bore, then chamber is cleaned. Temperature in the thousands of degrees proceed a bullet down the bore, vaporizing any micro water droplets. People forget about this simple fact about the firing process.
My hunting partner and I shot out 30 or more barrels on p. dog towns shooting 24-26K rounds a year, our equipment was top drawer. This Hunting partner was a Vice president, and electrical engineer of a major arms manufacturer in the country.
If water down the bore was going to hurt a bore, he and the other engineer would have known it. We have all heard the saying, "water does not compress" but there is no water in the bore to compress, tight patches plus the hot gases during the firing process eliminate all moisture.
We used Hart, Krieger, Shilen, barrels almost exclusively. We also shot out no telling how many Remington Varmint, and Ruger varmint in several calibers...all cooled with water down the barrel.
Best of luck with your air cooling
