Ruger GP100 gets extra dirty

[bikemutt]

Since I always end up with the post range time cleaning chores, I noticed this particular SS GP100 is always 2-3 times as gunpowder-residue dirty as any of the other guns we shoot, including another GP100 and several SP101 guns.

They are all firing the same Eagle bulk .38 special ammo with some occasional .357 magnum rounds loaded up. Round count is usually the same or close for all the guns.

Most of the discoloration shows up in the fluted areas of the chamber near the barrel, and the area where the chamber interfaces to the barrel (forcing cone?).

All these guns are quite new, less than 500 rounds, and meticulously maintained. The problem gun has been like this from birth.

It just seems odd to me that this one revolver is like the kid who can't find his mouth with a fork at the spaghetti feed.

Any thoughts?

More spaghetti.

Maybe it has a larger barrel/cylinder gap than the others. Rugers are always a crap shoot.

Check the weapon out. Im sure the answer is screaming at you.

I can see why you might notice that, but is it really a problem? :/

"...discolouration shows up..." Perfectly normal for SS. You're lighting a hot fire in the cylinders. Nothing to worry about. The carbon is there with a blued revolver too.

I've found that's one of the advantages of a blued gun. It doesn't matter that the cylinder gets roasted black -- you'll never notice as it's black to start with.

Thanks for the replies. It's not really a big issue, I just wondered why one out of 5 similar Ruger revolvers seemed to show more than it's fair share of carbon stains. I'll check out the barrel/cylinder gap and compare it to the others, that seems like the most logical place to start.

Agreed that blued guns mask the carbon stains, but they sure don't hide the fingerprints so well

Give Mil-Tec 1 a try and use a hair dryer as recommended by them. It won't stop the fouling but makes removing it easier. Just sounds like a little larger B/C gap to me, get yourself a set of feeler gauges and if it's over 9-10 thousands give Ruger a call they may be able to help you out.
