Madison, Ms
I have several rifles that are getting harder and harder to clean the more I shoot. My regular routine is Kroil then Boretech carbon... Followed by bore tech eliminator. Followed by kroil again. But this barrel is on the 2/3 shot out. I've been researching JB Bore Compound and it seems that there are more negative reviews than positive ones. It's a Remington barrel and I've tried everything to get it clean but it's never ending "blue".
What are you guys thoughts on this stuff
 
The real question is, by cleaning it are you seeing improved accuracy? If not then quit cleaning it until it doesn't shoot.

Well.. Back when I was really really shooting it, it shot a lot better clean. I've since purchased a few higher end rifles such as GAPs that I shoot alot more but I really don't like toting those around the woods hunting. The real gun in question is a sps Tac 20" 1:12 .308. I bought it in late 2009 and it SHOT. But like I said for some reason the damn thing won't clean up
 
There are a ton of effective copper removers on shelves and most seem to work well. I have Montana X-Treme Copper Killer on my shelf now and it works great. I've used JB as a bore prep, but think it's too aggressive to use as a cleaner.

You might want to try some Ultra Bore Coat. It did seem to help with copper fouling on the 2 bores I tried it on. There a tons of reviews on it all over the intrawebz if you're interested.
 
Jb is good stuff, especially on factory "rough" barrels. I use it when the bore starts to feel like there are restrictions in it. The jag kinda catches or pushes hard, then easy then hard. When factory barrels get that feel it's time for jb, gets them clean clean. I have used those products u mention and they work great in match barrels and also in factory barrels for awhile. I am always amazed at the black smut that comes out using jb, especially considering that the barrel was cleaned with kg1& eliminator. Never used it on a Krieger bartlien or brux, but it is awesome on a factory barrel. Alot of BR shooters use it with kroil, apparently they don't believe there is negatives to it.

No doubt. The BR guys seem to always use more aggressive cleaning techniques than the hunting crowd. I'm definitely that latter and only clean when my rifle tells me to.
 
I use Remington bore cleaner for all my needs. Very similat to JB. My theory on a barrel like yours is to keep the copper polished down but still in place in the voids. Works very well. It makes no sense to pull the copper from the voids with cleaning and then foul them again when you start shooting. IMHO. Give it a try and I think you will be very happy with the results.

If you are using brass jags, the blue after using JB might be coming from them. I've used JB when cleaning down to bare steel prior to applying Dyna Bore Coat (formerly ultra bore coat) and had the problem with blue patches until I switched to Dewey aluminum jags.
 
The gentleman who built my 300WM recommended to use it lightly every 200-300 rounds to prevent the carbon ring from building.
