Bought a bottle of Montana Extreme Copper Killer. After getting home I notice just below the name are the words "50 BMG special formula". Is this suitable for my 270?

I use it on my rifles (.243/7Mag/.300WM) and it doesn't hurt them. I do not leave it in the barrel for any length of time though. It is strong stuff. Do not take a big whiff of it - it will take your breathe away.
After using it on my 700P (chrome moly) barrel and I know I'm not gonna shoot it for a few days, I run a saturated oil patch (Kroil/Marvels Mystery oil) through it and then dry patch that out. I usually clean just prior to shooting.
I have been using Copper Killer for about 2 yrs now and have noticied no decline in barrel life or accuracy. It will get the copper out.
I also use another of their products; Bore Solvent and it gets carbon and powder residue out great. After about 3 wet patches, with 1 dry patch after each of those, I don't have alot of anything in the barrel. So then when I hit it with the Copper Killer I don't see alot of copper residue on the patches. JohnnyK.

I highly recomend Bore Tech Eliminator and Wipeout. These products are better copper removers than Montana Extreme and will not hurt the barrel no matter how long you leave them in the barrel. Any amonia based cleaner can be harmful to the barrel.
I use Bore Tech at the range for quick cleaning and Wipeout at home for overnight soakings. Do not use brass jags with Bore Tech. It will eat the brass jags and give you a false copper indication. Use a nickel platted or plastic jag.

Not sure but I think you need a different barrel solvent/cleaner for each calibre.

We use 2 of KG Industries products named KG-1 Carbon Cleaner and KG-12 Copper Remover in conjunction with Kano Laboratories Kroil Penetrating Oil. We liberally dose the bore after a range session and while still at the range with Kroil and let it soak until we are ready to clean the weapon.
KG-12 is water not ammonia based and won't etch the bore, and removes copper like nothing we've ever used before.

Wipe out and I'm done! I have used dozens of commercial and home brews including electrical and cleaners intended from toilets to the space shuttle. Wipe out has been the best cleaner copper remover I have ever used in over 4 decades.

The guys that started this thread were cleaning their muskets while they were home on furlough from the Civil War.
There's always a chance someone needs a little info for cleaning...
I myself tried CLR in a couple of mine recently...cleaned really good..
BUT....
Kept getting a residual coating on the bullet of cartridges chambered while hunting....even after doing a couple regular cleaning with
wipeout...
Rifles still shoot really good...guess if barrels get so cruddy wipe out can't clean'm then I will run some more clr.....
Though...I think I will stick to wipeout for general cleanings....
