Barrel carboned up - thoughts on Gumout Regane?

[doverpack12]

Great information. My 243 which I carry in my vehicle and shoot regularly all of a sudden threw a shot foot high left then another foot low right this winter while shooting at the range after I had decent accuracy up to that point. Also stuck the bolt on those two. I cleaned like crazy and accuracy came back into 0.2-0.3" range which is as good as that rifle will get. Accuracy didn't last long though maybe 12-15 rounds then it shoots under an inch for a long time. Carbon fouling was extremely heavy. It's on the bench now. I've found on my 260 and this 243 that CLR will cut the carbon or at least get rid of whatever type of slick hard surface develops in the grooves and allow the other carbon cleaners to remove it. CLR will remove blueing fast so I push a patch through then wipe the muzzle. I just do a few patches then dry patch and repeat for maybe 15-20 patches. After that wipeout and C4 will do their jobs. I am getting the bore pretty much free of copper fouling prior to CLR. Wipeout with accelerator has been doing particularly well. I don't always use CLR but when I'm done cleaning using boretech eliminator and C4 or wipeout and I look in the muzzle if I see dark grooves and shiny rifling it's back to CLR.

Very interesting that this post comes up at this time.
Yesterday I cleaned my 6.5 CM Ruger Precision Rifle with CRC Motor Treatment, a liquid carbon cleaning gas additive.

The barrel had over 1,000 rounds through it and I had never before used a carbon cleaner. Glad I did. It worked very well. Patches came out black for a while and then a very faint gray when I stopped using it after 4 different patch runs.

Litehiker - did you have to fill the barrel and let it soak, or did you use bronze or polymer brushes?

Don't mess around if you want it sorted with no brush work...

Pick up to small bottles of Wipe-Out and the Accelerator,,, it will last you a life time...

And you can let it sit in your barrel for 24 hours with no damage...

Run a few looooose patches of WO,,, let stand for a few minutes,,, then run a looooes wet patch of A,,, let stand...

Repeat this over and over till the patches come out white...

The trick for me is to not remove all the fowling since I can get my boolitz back onto target with in 4 to 7 shots,,, then I keep going till I have more outters then inners,,, 200 to 450 ish per cleaning...

This is dependent on how hot my loads are,,, my main shooter is at 1300 rounds with 5 cleans and never a brush...

This barrel will make it to the 2500 to 3000 count before the accuracy starts to drop off,,, it will Sloooooowly tapper off to the 1 MOA and larger groups at 4500 to 5000 total rounds... I'm ok with a 1 to 1-1/2 MOA barrel for hunting and 600 meter stuff...

Find what works for you is what its all about...

If you want to see dirty powder,,, try Varget... Ha... It leaves one 4@!! of a mess,,, but dam,,, it sure is consistant in the mid size cartridges...
