Removing a metal burr on chamber lip

HELP.......I recently purchased a brand new model 700 VSSF II. After shooting a few rounds through it, we notice that all the cases are coming out scratched in the same place. Looking up into the bore, you can see a very, very small burr on the lip of the chamber.........right where the rim of the case is pushed up against when locking the bolt down. The scratches occur even if you just chamber the round and then remove it without firing. When doing this, the bullet is scratched as well. Also, the rim of the case has a small dent, for lack of a better description, that is always in the same place in relation to the scratches on the case. Any suggestions on the proper way to polish this up? Thanks for any and all suggestions.

I'm having a tiny bit of trouble visualizing exactly where the burr is, but it sounds like you can simply glue a 1/4" X 3/4" strip of 220-400 grit or so sandpaper to a foot long piece of wooden dowel to polish it out. See if you can take a large paper clip or other similar sized wire, straighten it out and bend a little hook on the end and see if you can feel the burr that way.

If you aren't 100% cetain and it is a new gun, you may consider sending it back but personally I'd be like you and just polish it out.

Thanks for the suggestion. Like you stated, I'm not sure I want to send it back to Remington, thats why I'm asking here for suggestions and yours sounds like a good idea. I was afraid my description may not be easily understood but I tried. The "burr" is right on the edge of the chamber. After removing the bolt and looking up the bore, its barely visible right on the edge of the chamber....not up where the shoulder of the case would be but back where the rim is. The dent ocurs on the forward side of the extraction groove of the case. The two scratches occur the full length of the case. Not deep scratches but enough to notice. Hopefully this explains the area a little better. Sorry about that. I will try the paperclip idea also, but the burr can be seen if you know where to look. Thank you sir for the reply.

A small piece of fine scotch-brite put into a slit in the end of a dowell chuck it up in a drill motor and keep it moving in the chamber and pollish away!! dancing

and don't forget to flush the chamber and bore well afterwards.......get the gritty stuff out.

The little dent in the rim is where the extractor jumps over it when the bolt is closed.

If the chamber burrs is localized use the dowel and silicon carbide paper trick. If it is a sharp edge all around the chamber a 5/8 counter sink on a long wood bit extension will remove it but use HAND power only with just a little pressure one part of a turn only.

What you need is a $10,000 lathe, a barrel vise, action wrench and a little piece of 200 grit emory cloth. Takes it right out. Wink

Seriously, what you're describing is quite common in factory barrels ever since US firearms manufacturers went global. Custom gunsmiths routinely check for and remove such burrs before letting any of their guns out of the shop. Good gunsmiths, that is.

Any of the methods described by the other posters will work. No big deal.

You are not alone.
My Rem 700 ADL in 204 Ruger had a similar tool mark just inside the chamber. It looked like a fine burr about 10-degrees long around the chamber.

I used a fine grit machinists round/tapered stone to draw polish out the burr.

The rifle shoots like a champ -- 6 x 5-shot groups in a row, average 0.6"

Best regards

I would send it back to Remington, to the attention of Tim Butler, Custom Shop Manager. Tell him of your problem. It sounds like the chamber was not chamfered and polishied after chambering. To fix this correcly the barrel needs to be removed and put into a lathe, Chamfered and polished. The re-installed onto the action. This is one of those things that slip by in quality control at Remington.

Thanks for the additional replies.

Longshot,
I called their 800 number and got some extremely rude woman who would only say, "box it up with a written decription and send it back". Period. She wouldn't even try and answer any of my other questions. I didn't have a good feeling about it so I emailed them on 9 January. The automated email reply stated "If your issue remains unresolved, please update this question at
(link provided)". So after 2 weeks I replied to that link. Three weeks later, still nothing........until today. They send an email stating "Due to a computer glitch your correspondence was not discovered until today and again, we sincerely regret this has
happened." Told me to call Parts and Repair dept......so I did and waited for 30 minutes until "Pete" answered. He said to send it back and is sending a box and shipping label to me. I'm nervous as hell to say the least. This whole thing has me very skeptical of what kind of condition this will be returned to me in. Part of me says to just live with it and part of me says for a $1000 dollar gun, quality control should be somewhat better than this and that they should somehow make this right.

Guess I can stew over this for another week until the label and box arrives that I'm to ship it back in. Had the gun for 2 months now and haven't even been able to shoot it other than the 5 rounds before I discovered the problem.

My local gunshop/gunsmith is an authorized Remington dealer and repair facilty. I've had a couple problems with Remingtons and took them to him. He fixed them at no charge under warranty and sent the warranty claim to Remington. Maybe there's an authorized repair facilty in your area?

Ask Malm,he is from utah and knows all.His book is coming out soon.Or fyj,or vapodog. They all should know and help you out.work on it yourself like they say and your warranty is gone.Yes its simple to fix,but listen to them.They are known very well in there little world,whatever that my be? Only the shadow knows!Serious,find a factory rep near you and go from there.Fot the others don,t care about "YOUR" warranty as they didn,t put out the monies for your firearm.
