Save your time and money and quit cleaning your .22 barrels. Clean your chamber and action. Done. I have .22's with 10,000 rounds down the tube that have never felt the touch of a swab. All group the same as they did after 100 rnds.
Same goes for center-fires - almost. Let accuracy be your guide. But, I can tell you I rarely clean a CF bore anymore either. I usually change the barrel for worn throats before I can get around to cleaning it.
P.S. The cleaning supply vendors and barrel manufacturers do not want you to know this!
