I hate copper fouling

[j_22250]

So I got this rifle that shoots groups damn near in the same hole, but after about the 7-10thth shot they spread out to about an inch; still not bad. I usually clean after 4-5shots cuz other wise it takes alot longer; by the way hopes benchrest #9 sucks. I'm gonna get some barnes. I bought this gun used a couple years ago. shot a box to sight in and stuck it in the closest. I shot another one through it and wasn't impressed so i cleaned it out good and made some handloads for it. I was real impressed until my copper buddy showed back up. Oh the humanity..... will it ever end? From now on ever new gun I get is gonna have a stainless steel barrel on it.

I got scolded for using CR-10 (Barnes stuff) use Butches bore shine or Tetra.

Gunsmith says CR-10 can etch a SS barrel, dont know if he cared for it in a steel barrel or not? I havent seen any copper come outa my Lilja anyway, gets sooty but have seen no metal come outa there yet, and dont see none in there.

Might just go with butches or wipe out then. It took me 2hrs. to clean last time, letting the hopes soak for about 30min. each time. Gun is a savage and i hope it stops doing this or at least gets to the point were it is not affected as much by having a little copper in the bore.

If you only use CR-10 for the stubborn copper and only let it sit in the barrel no longer than 10 minutes (like I believe the directions say) you will never harm your barrel. CR-10 is a good ammonia based product that does remove copper relatively quickly. But after seeing some studies on lab rat exposure to ammonia, I have quit using ammonia based and petroleum distillate solvents.

I am still using the enzyme based cleaner formerly known as Coppermelt for most of the stubborn coppered barrels. It is no longer made unfortunately which borders on the edge of tragedy not just inconvenience. But when I am cleaning custom barrels or fair factory barrels, I use Bore Tech Eliminator. It is distillate free, ammonia free, and gets copper out almost as fast as Coppermelt. And it actually smells nice!

I know a lot of benchrest shooters who use Butches and there is nothing wrong with it. It is a good all-around cleaner. But it can't hold a candle to Eliminator. Some of my fellow shooters in my region still hold fast to the Butches though like they are afraid to try something new. Oh well.

Sounds like a good solvent and a barrel break-in are in dire need!

Thanks for the info good grouper. I dont think the barrel has ever had the copper removed from it. I am in the process of breaking it in though as i do my load development. I think i have my load jst need to do some more testing(42grs. varget and 168 sierra hpbt seated .010 off the lands). I just sent in an order to midway and i ended up going with montana x-tream bore cleaner. After reading the reviews it was comarable to cr-10 and just as good as butches plus it's on sale right now for 2.99 a 4oz bottle. So i ordered 3. I am also gonna try some kroil have herd great things. I never thought to use this in guns before. This gun seems to shoot at its best when all copper is removed. I read a thread on another site that said not to remove all of it cuz it acually fills in some of of the tooling marks. every gun is different though and mine shoots at its best when clean.

Try Wipeout with accelerator, it's like color TV, you'll never go back.
