Crud ring on the other end
 

Took my ML to the range yesterday , fired off a total of 7 shots. No swabbing between shots etc. and was able to keep 3" groups at 100yds with open sights. What I did notice was that a ring , which seemed to be plastic residue from the sabots , developed at the end of the barrel. This made loading the 4-7th shots difficult. This is a different "crud" ring from what the rest of you guys have been talking about where the bullet "seats". Any ideas on how to avoid this ? I was thinking powerbelts, since I'm using a CVA.

=============================================

By swabbing more often... perhaps every 2nd shot like most of us do! All you need is a small, empty spray bottle & fill it 50-50 with Windex & rubbing alcohol... works marvelous for cutting fouling & carbon.

You will also need to discard the almost-assured weak "Blackpowder Cleaner Solvent" you are probably using (T/C-13 & others) & purchase a solvent that removes plastic. It will say-so on the label. If you are shooting copper-clad bullets, you'll need a solvent that removes copper.

Failure to do so will eventually result in declining accuracy... sometimes rapidly.... like overnite!

its only a 1/4 inch white ring at the end of the barrel , just licked my finger and rubbed , came right off. This is being cause by the plastic of the sabots correct ? Accuracy didnt change , just the ease of getting the bullet in past the ring.

Then you should develop a routine of licking your finger and rubbing. :D

already have that routine for the wife ...might as well us it for the ML too :D

That sounds like powder residue, not melted plastic sabot residue. A wet finger will take powder residue right off - but plastic has to be scrubbed/dissolved off.

How much of what kind of powder are you using?? That will tell the tale of your situation I think.

80 grains of 777 ...loose

Mark's real-real close with residue theory... actually he's 99% right. The 1% he's missing in his post is what turns the fouling white. That is salt concentration from your powder.... usually occurs after the bore has not been cleaned for a spell or been left out in the open air of your home, garage, auto... etc -- not hardly related to plastic fouling there. Best to keep your fouled MLs in a hard shell, poly-foam gun case that keeps it air-tight inside your home after range work. When hunting with a fouled bore, you can do the same but the rifle temperature must be acclimated from cold to warm much more slowly.

Remember what I mentioned about cleaners.. use the proper ones & swab frequently for best accuracy & easier removal of bore gunk.

I clean after every trip to the range or shooting. The ring is only a 1/4 " wide at the end of the barrel.


Have heard the opposite , my dads ithica was kept in a foam case with poly foam. When I took it out the other day the foam "fingers" had left what looked like fingerprints all over the gun. I keep my firearms in a gunsafe when stored. 8 out of 10 ppl I've asked state to never keep your guns stored in a case
