[QUOTE="Pdvdh, post: 352166, member: 4191"] The scarry part just keeps us alert and on our toes. :cool: The positive part is once the bore is coated then it's coated for a good long while... lightbulb All of my bores are now treated with the stuff -> long lasting = corrosion protection. None of my 284 and larger caliber rifle barrels lost velocity. A 300 Win Mag gained about 50 fps, and I had to reduce my powder charge accordingly to bring it back into the sweet spot. So I haven't experienced a loss in velocity. It is possible powder charges may have to be reduced after GJ treatment in order to tweak MV back to the sweet zone. I'm learning that I do have one bore that wants to copper foul a bit inspite of the Gun Juice treatment - albeit less than prior to GJ treatment. So GJ won't eliminate copper fouling in all bores with the tendency to copper foul, but it will reduce fouling. I just purchased an AR-15 5.56mm with a chrome-line bore but don't plan to Gun Juice treat that bore. It's intended to be used like a high pressure fire hose. As long as it makes a lot of noise and the bullets come out the barrel reliably, that's good enough for me - fouled bore or not. As has been mentioned, proper GJ treatment is labor intensive. The manufacturer's instructions are less than crystal clear that the bore should be stripped of all powder, carbon, and copper fouling prior to each application of GJ and before fire setting the GJ to the bore. So for a stainless barrel, where 20 treatments and firings are recommended, this means obtaining a squeakly clean bore for "each clean the bore to the bone & shoot once" repetitions. The repetitive cleanings will cause a person to learn a bit about the most effective copper removing bore cleaners on the market. I ended up settling on KG1 (carbon remover) and KG12 (copper remover) products as better than any other product I've used for rapid carbon and copper removal. Non-ammonia based. They kick butt. However if you have a bore that stubbornly retains copper - then Wipeout with or without the accelerator might be the best way to go. Due to the longer dwell time with Wipeout, just plan on extending the GJ treatment process out over a longer period of days.

I believe it will extend the number of rounds down the bore before accuracy deteriorates and I believe it will add to the corrosion resistance of a fouled bore. I don't know if it will extend throat life. Someone would have to pay me to devote the time and resources necessary to demonstrate that type of a claim. [/QUOTE]
