Sorry for digging up an old thread but, I'm using BT Eliminator and am wondering if there's any updates on whether it will/does corrode barrels.
I've been using BT Eliminator for several years now over ~ 10 barrels. I don't wipe off the muzzle when done cleaning and typically leave BT C4 or BT Eliminator in the barrel for extended times [hours] and overnight.
I have not seen rust on the muzzles => does it rust some and not others? Is chromoly more susceptible than stainless? Is there something else going on?
BoreTech does recommend leaving some in the barrel as a short term rust preventative.
Thanks.
Call Bore Tech - their technical staff is terrific. They will give you info on extensive tests that they conducted then you can make your own decision.
Cleaning rifles is one of the most controversial subjects I've ever seen. Just watch the video's on the net and you'll see what I mean.
I switched to Bore Tech products about 2 or so years ago. I use the two part system, i.e. C4 then CU+2. Prior to that, I used Shooter's Choice for about 30 years and was completely satisfied with it. The only reason I switched was wifey developed a sensitive to the odor. Bore Tech products are odor free.
After 2 or so years of using Bore Tech two part system, I can say that it does a terrific job of removing carbon and copper.
Here's the rub - I began developing clean barrel flyers in my custom barrel rifles. Plus, it would take some barrel seasoning, i.e. about 5 shots before the barrel would shoot to its full capability. This puzzled me to no end. Thus I began a research project. I wondered if I was doing too "good" of job of removing copper. The reason why I wondered was Shooter's Choice does a fair job at best of removing copper and for 30 years of use I never had an issue with clean barrel flyers or having to "re-season" the barrel with copper to obtain consistent precision.
After watching gunblue490, tiborauaurus Rex, Panhandle precision, and 8541 tactical video's I decided to test their premise of "copper equilibrium" and "minimal disturbance cleaning" relative to maintaining precision. I know this is rifle cleaning heresy with the gun cleaning culture because all the "experts" and bore scope guys swear that you have to remove all the copper. Maybe their right, I don't know but I wanted to test a different approach.
Why my testing at this point is still under way, the initial results indicate there may be some basis to the aforementioned claims regarding minimum disturbance cleaning since I've eliminated clean barrel flyers and reestablished consistent precision without have to fire "fouling shots."
So far I've tested two methods, both designed to remove carbon fouling. I've cleaned after every 40 to 50 rounds. Procedure A: bore tech C2 only which does an outstanding job removing carbon and some copper much like Shooters Choice. Procedure B: Hoppe's 9 which does a good job of removing carbon fouling.
Both procedures have produced my desire results - i.e. elimination of clean barrel flyers and consistent precision without having to "season" the barrel. However the testing is not complete yet - I need more data to draw any absolute conclusions.
Bottom line: don't be afraid to try something new if you are not getting the performance results you want. Test for yourself and make your own decision. I'm only interested in performance results, not how the bore looks. If performance goes sideways then a bore inspection probably has value. But I wouldn't base anything on just looking down the bore - I would use performance results as the basis.
