Re: Best Bore Solvents
I'm late to this party, but I've used a number of different bore cleaners over the years, and at this point in time, prefer KG Products KG-1 solely for carbon, and Bore Tech's CU+2 solely for copper. The two best products I've used that remove both carbon and copper are Bore Tech Eliminator and Wipe Out. If time is not of the essence, foam the bore with Wipe Out and 12 hours later my bores will typically be copper free. The Bore Tech Eliminator will clean the bores faster than Wipe Out if time is critical, but will require more applications, swabbing, active cleaning time, and attention.
I've repeatedly tested Bore Tech Eliminator versus CU+2 down several of my rifle bores. After the Bore Tech Eliminator patches were starting to come pretty clean, I'd patch the bore with CU+2, and suddenly the patches would turn notably darker blue again. My conclusion: the CU+2 is somewhat more efficient at copper removal than Bore Tech Eliminator.
KG-12 also works pretty darn good for copper removal, but I rate it behind the Bore Tech products because it's so hard to tell if all the copper's been removed - shy of examination with a bore scope. The culprit/problem is that KG-12 is a yellow cleaning solvent, and the patches don't turn blue like the Bore Tech products when removing copper. They turn from lighter yellow to darker yellow/light orange. And my eyes aren't good enough to calibrate between those shades of yellow to know when the copper is gone when using KG-12 for copper removal. In addition, I can confirm several experiments/experiences similar to MontanaRifleman's. I've followed up behind KG-12 cleaned bores that I felt were copper free with both Bore Tech Eliminator and Bore Tech CU+2 products, and received blue stained patches, indicating the Bore Tech products were removing some residual copper. Not a heavy blue staining by any means. But the Bore Tech products did remove some additional copper fouling that I'd missed with the KG-12 copper removing solvent.
If I was restricted to the use of two bore cleaning products, my current picks would be KG-1 for carbon and CU+2 for copper. CU+2 has proven slightly more efficient on copper than Bore Tech Eliminator, in my testing. I also like the CU+2 for the reasons mentioned by Broz. Doesn't dry sticky and can be left in the bore as a corrosion preventative until ready to go shoot again. I can't comment on whether or not CU+2 improves consistency of clean bore impacts down range. But Broz shoots a butt-load of bullets down range. He'd know if there's something to it - at least out of his barrels/rifles.
If I was restricted to one bore cleaning product, it would be Bore Tech Eliminator, because at times I have the need to get a bore cleaned and return it to action in short order. Wipe Out is a great one application product if you can afford to leave the bore soaked overnight.
I can't imagine anyone being too disappointed purchasing and using these products.
