I have for years (50) used Remington gun oil, but came across a small bottle of ProShot 1 Step CLP. I started using it on my Colt 22 Lr. as I had been having some trouble with FTF starting a few years back. I had been doing full tear down for cleaning, so the gun was clean, but still almost every mag I would have a FTF . After using the CLP I have not had a single FTF with a total of 1000 rounds fired. And I started using it on all my hand guns. Funny thing is all the guns have shown a pronounced increase in accuracy. Not only me but also my wife's gun, it is so apparent that she has ask me what I did to her gun.
