Cleaning a 7x57 Mexican 1910 Mauser
I have just completed doing some custom work on the Mexican 1910 7MM (7x57) Mauser using the original barrel. It was and still is very dirty.
I have tried the Blue Wonder gel cleaner, Shooter's Choice, Kroil penetrating (creeping) oil, Ballistol Lube and even the electrod rod cleaning system with ammonia. Before the intense cleaning, the gun was shooting 10" groups @ 50 yds. Have not shot it after cleaning but I can not get it clean. After every brushing, patches still come out black.
Any suggestions on how to clean this thing? Thank You!

With 10 inch groups, I guess it's time to break out the hand lap. Obviously can't hurt it.
There was a cowhand once who said that Shakespeare was the only poet who wrote like he'd been raised on red meat.
No man in his right mind will play with a gun. I've seen show-offs doing fancy spins and all that. No real gun-fighter ever did. With a hairtrigger, he'd be likely to blow a hole in his belly. L'Amour

you might have to accept the fact that you need a new barrel. 0 -
Mike said it....
I've seen some filthy and abused guns. I have never come across one that shot that bad without having other problems. But, I never had one that would not clean up after going through all of the procedures you mention.

We will most certainly hang separately.0 -
Before you go swapping barrels, try lapping it. Some novices may not be familiar with what it can do for a barrel, but most experienced gunsmiths are.
Don't fire lap it though. That's for folks that don't know how to properly lap.

Before you wear yourself out ... shoot it and see if there is any improvement in grouping. If not check your boresize against the size of the bullets in the rounds you are using.
If the bore size is good, there is no damage to the barrel crown and the stock fit is good then you can either keep cleaning or rebarrel.
If the patches are still coming out dirty after every application of the brush you still have crud in there, regardless of the cleaning methods used. While the bore is obviously "dark", with a good light source how strong does the rifling look and is there any sign of pitting. If rifling is strong and there are no serious pitting signs then that is further encouragement to keep cleaning.
Lastly, if you continue cleaning stick with one product/method as switching around can actually decrease the effectiveness of products because of interactions between tose products.
I have some pre-1900 Mauser and Nagant rifles that eventually cleaned up pretty good, but it was a lot of work. And the best product I have found is the Blue Wonder ... layin a generous amount while brushing, let it sit for 15-20 minutes apply a small amount to the brush and give it another good scrub followed by patches ... then just do it over and over, eventually the crud will quit coming out. However I will close with the comment that none of those rifles shot as bad as yours, and today all will shoot into less than 6 inches at 100 yards, even the 71/84 blackpowder Mausers.
If you only have time to do two things so-so, or one thing well ... do the one thing!0
