Earlier this year my Lilja barreled .17 Remington started having accuracy issues. It seemed no matter how much I cleaned it or what I used to clean it with it would only minutely help or not at all. Took it to the range last week with a few different loads and 2 or 3 or 4 shots would group OK then...wow!..next one would miss the entire target or if it did hit the target somewhere it would keyhole. Barrel is way too new for it to be toast. But then I read about using Easy Off oven cleaner got get stubborn carbon out of a bore. Easy Off down my $400 barrel? Oh hale no! But then well, it shoots like crap now so may as well try it. Went and bought a can of it (Heavy Duty) and sprayed some on a patch and ran it down the bore. Waited a bit and did a second patch. It was black! Did a few more until they came out clean and after a few dry swabs followed by a couple of alcohol moistened patches then finally a patch with some Kroil on it I went back to the range. Land sakes alive it shot like new gun again. It was windy but shot a bunch of less than 1/2" 4 shot groups with the dang wind always opening up the 5th shot. Had I settled for three shot groups I would have had several that measured 1/4". I was shooting 20 grain Vmaxes and 25 grain Vmaxes and 25 grain hollow points and they all shot well. I am so happy and relieved that something finally worked.
And for those that think oven cleaner might be too caustic for rifle bores I tried a little experiment (thanks, Keith!) with a section of another stainless steel barrel. I sprayed Easy Off all over it until it was foamy glob and left it. Came back several hours later and went...oh oh! It etched the steel! But no, it had only dried on there and left some residue. Came right off with some spit and a rag. Clean too!
So I am not saying that this will work for you but if you ever do get a barrel that suddenly (or perhaps not so suddenly) shoots like crap then you may want to try this. I did and it worked for me so thought I would share it with you guys.
