I'm new here and I'm not sure if I have this in the right place but I think this pertains to all of us handloaders that shoot a lot.

I have had a bottle of m-pro 7 for a few months and have honestly had terrible results. Following the instructions exactly as stated this stuff is very low in performance compared to other products that I have used. I won't mention their names because I don't want to sound like I'm trying to pimp a product.

I was cleaning a pistol with a stainless barrel yesterday that had coppered up all the way down the riflings and ran the m-pro 7 through twice (letting it sit for 5-10min) and barely any copper came out. I tried another well know copper remover and after one good swabbing for 5 min it was totally removed. I have had similar results in the past.

I really want this stuff to work and love the fact that It is almost odorless unlike other copper removers.
 
MPro-7 does NOT remove copper.
Repeat, it does NOT remove copper.

That said, however, MPro7 is my absolute BEST solvent to clean powder fouling... the best.

I then follow it with KG-12 to get the copper exposed by cleaning out from behind what was the powder overlay.
KG-12 is the ONLY stuff I've found over many, many years that flat sucks all the copper off literally in minutes, and it
also gets whatever powder is left over

No matter what I've tried in the last 40 years, I always come back to the fact that gun cleaning is a two step process: Powder fouling first, then copper remover.
Butch's Boreshine comes second as a 1-stop cleaner, but even Butch's takes its own sweet time to quit turning blue.
 
I've also tried the MPro Copper cleaner.
It's now sitting on my shelf (unused), and the KG-12 is what goes to the range w/ me.

Again, MPro-7 gun cleaner/solvent is great for powder foulding.
 
Thanks for the clarification.

I use Hoppe's Elite gun cleaner, which is the same as MPro-7 (same manufacturer, different label).

Its not odor free, but the best copper remover I have found is sweets. Hoppies benchrest is decent too, but it needs to soak in alot longer to be as effective.
 
mpro 7 copper works though it's min. of 30mins. and if there's still traces i redo it again.
after getting it squeaky clean i haven't use it again. my routine now is mpro7 cleaner and mpro7 clp.
with the mpro7 cleaner , letting it sit for 30mins with really lots of fouling don't do the trick.i have to redo it 3 times. so with heavy fouling don't expect a quick cleaning time.
but after range time and i let it overnight. it only takes me several few mins of cleaning.i end up with mirror like shine barrel. <--- don't know the tech term to describe that :(
 
No comparisson to KG12. Try it and you won't be dissappointed. I have no commercial connection with KG12. I was just impressed when I discovered it.
 
Haven't tried M Pro 77,but Barnes CR 10 is far and away the best I have used for copper removal.I shoot a .257 Wby,(I know it's a handgun thread),that gets coppered up pretty bad.The Barnes stuff just plain works great.
