I was getting ready to send a Ruger 5.56/.223 down the road because I could only get 1 1/4" groups out of it. Started thinking about it and realized that I had not cleaned the barrel in a while. Did my Wipeout routine and it is back to shooting 1/4" five shot groups again.
I have had the SAME results with many other rifles, notably an A Bolt Medallion .270. Every time is gets to shooting an inch group, I just do the Wipeout routine and the groups shrinks back down to 3/8" for a three shot string.
I have noticed that it usually takes few shots to get the barrel shooting right again (4-5).
Just a two second squirt from the chamber end and let it drain out of the muzzle. Been using this stuff for at least 10 years.
