Recently I shot a Walter Uzi rifle. Out of the box the accuracy was impressive for a "novelty gun".... But about 300-400 rounds of Remington Thunder Bolts later the accuracy became awful. I had trouble hit a 12"x14" box at 7yds! Upon inspecting the box the bullets appeared to hitting sidways.
I noticed the chamber was extremely dirty so I decided cleaning it would be a good start. When trying to run a 22 cal brush through the barrel it stopped 3/4 of the way through. I tried a 20 cal brush it would go through but was not successful in clearing what ever it is. I also tried tapping on it with a 22 patch jig but still no success.
Will probably take it to gun shop this weekend but thought I'd check on here see if anyone else has experienced something similar.

Thunderbolts are very very dirty. Plug the muzzle end. And fill the bore with your favorite solvent and stand the gun up on end and let it soak overnight. PS are you sure there isn't a squib in the bore?

There must be some kind of partly obstruction in your barrel. If there are dents inside your barrel or a bad machined riffling then lead particles can foul and fill up a barrel. This obstruction can damage bullets if they rub over and making them tumble in flight. Discuss the matter with Walther. You were using standard, factory ammunition, so the issue should be Walther's.
If they feel it needs to go back to the mothership, they should send you a mailer

Yeah I don't plan on buying Thunder Bolts again. I can get a cleaning rod through it with a 20 cal or smaller jag or brush. I think there could be some kind of small obstruction. I will try filling it with solvent though... It's worth a try... Thx

That's probably what I will end up doing. I was just hoping to avoid the customer service run around and the months of waiting.

Sounds like a bad case of leading to me. Look into a lewis lead remover. Not sure if they make then for .22 or not . You may be able to buy just the screens(which are brass) and cut one to fit on your jag and bore and you keep pushing them through until you get all the lead out. When its bad the lead will plug up the screen and shavings will be pushed out the barrel.

It's now also happened to a Smith and Wesson Victory. I can see down the barrel and it looks like the is a ring of something (I assume lead). I was shooting the same Thunderbolts through it. I have also shot Armascors through it too. Any ideas on what to do? I cannot get 22 clean brush or jag through it!

After a little research I'm pretty sure it's the ammo. I've always been a fan of Remington, but I'm done with there Thunderbolts. I will pay for extra for better quality! Would still appreciate any suggestions on cleaning out.

Copper "Chore Boy" aka "Chore Girl" scrubbing pads found in your supermarket. Cut one apart and wrap it around an undersized and worn out bore brush (trial & error here). You can use it as is or with Ed's Red, Kroil, WD-40 or the solvent of your choice on it. Works like a charm, is inexpensive and requires no special equipment.

Thanks for the reply... I'll plan on giving that a try!

Oh my how many rounds are you running through them 22's before cleaning them? When you shop for the copper wool. If they don't have the chore boy and you opt for another. Be sure it's not copper coated steel. Some packages will say it is. Others will not. Our walmart does not carry chore boy. I took a magnet along to check. Ended up finding some at the Weis grocery store.

Also should I be concerned about damage to the firearms due to the possible increased pressure? The obstruction appears to be about an 1" from the chamber and only about 1/8". It only restricts the barrel down to approximately to 20 cal. (A 20cal. jag will pass through)
