Hey everyone,

I was out last week with my 10/22, and put a half brick of winchester, and a half brick of remington thunderbolts through it. tonight when i went to clean it, my bore snake would not go through the barrel. it would get stuck about an inch past the chamber. I looked down the barrel with a flashlight, and it appears something is sticking out of the inside of the barrel. Im very anal about cleaning my guns, and always strip and clean them after every use, and this is the first time that i've encountered this.

I wish i could get a picture to turn out of this... anyways, i was doing alot of "rapid firing" with 25 round mags. My question is:

could it be that i heated up the barrel and damaged the rifling? or just a chunk of copper jacket or lead stuck in the rifling?
has anyone else experienced this?

im hoping my barrel is not pooched....
 
Probably a lot of lead buildup in the throat. Quite normal with rapid fire and a hot barrel especially a newer barrel where there's still some rough chatter marks in the throat. I would suggest using a rod with patches from the muzzle with a muzzle guide first. Your boresnake might get stuck if there's enough lead built up.

It is almost impossible to screw a .22LR barrel up by shooting it, short of shooting it with the muzzle blocked. I expect you have a lot of leading as the others have stated. Try a brush and good lead solvent to get it clear, it may take some elbow grease and patience but should be fine in the end.

Regular solvent and patches always work for me, occasionally it takes a pass or 2 with a brush. My bro in law thoroughly enjoys the BC mag loader and blazer bulk packs so I get to deal with this quite often :) I flip the rifle over in my cradle with the bolt locked back and lay a piece of paper towel in the action to catch the crap that comes out of the bore so I don't have to tear it down every time.
 
I had the exact same problem with Thunderbolts. Here's a link to the post http://www.canadiangunnutz.com/forum/showthread.php?842019-Ruger-10-22-Takedown-Barrel-Problem

You can push down a cleaning rod (aluminum or brass) to force out the lead buildup. I have no lead buildup problems with any other lead or copper plated ammo, so I just put the Thunderbolts in the back of the ammo locker for now. May try them again after my 10/22 TD has a couple of years of rounds through it.
 
well, its confirmed. definitely lead buildup. still unable to get it out even with rod and brush. i"ll try soaking it with hoppes#9 hopefully it will loosen it up a bit. thanks for the replies everyone! i really thought i screwed my barrel up at first
 
Just try a cleaning rod without a brush and gently tap it with a hammer. Use a brass or aluminum rod and you won't hurt the barrel, but you may sacrifice your cleaning rod. Had to do this twice so far and been lucky. Rod and barrel were ok after.

Here's some pic's of what came out

If that fails mix up some white vinegar and hydrogen peroxide 50/50 and fill the barrel with it. Wait 20 mins then flush with hot water. Repeat until clean. It will break the lead down to a sludge and you will eventually be able to brush the rest out.
 
after a few hours with a rod&brush and hoppes#9 solvent, it finally came out! It was a real stuborn bastard!!! but now my bore is good as new. No more thunderbolts for me... ive never had a problem with winchester or federal. thanks for the tips everyone!

could have also got a wood dowel and poked at it, would be faster, wouldnt damage barrel
 
For future: take the trigger and bolt off the receiver. Carefully indicate in the rear of the receiver a mark in line with the centre of the bore. Take the barrel off. Drill a hole about .25" or slightly larger through the back of the receiver so that it's true - lined up with the bore. Clean/break the edges of the hole, clean the swarf/filings out of the receiver, Reassemble the barrel, check that the hole through the receiver is actually in line with the bore. Reassemble the receiver (bolt, trigger group) and then reassemble to the stock. Test fire - heck, fire a lot.. then - when you clean - take the barreled action out of the stock, remove the trigger group and bolt, and clean from the breech end with a rod without having to take the barrel off (preserving your scope's zero if you shoot with a scope). (save the bore snake for out in the field, and if you have a sectional rod in the field, use it from the bore only in emergencies)...

That's what I'd do. That's what I've done with two 10-22s now. No deleterious effect on accuracy, no wear and tear on the muzzle/crown from cleaning.
 
Or - you could just get the Take Down model that makes cleaning the barrel super easy. Definitely going to try your mod on my SR-22 though.
