Hey guys, is this a problem......... Went to the range the other day and some of my loads were a little too long, probably around 2.81ish. I know they should be 2.800 COAL but I'm finding that my seating dies tend to adjust themselves throughout the process. When I went to chamber them, they were really hard to close the bolt on. Later on I noticed the back of one of the lugs looked like it had been scraping against the action. So my concern is; Did I do any serious damage to my gun? Is this a big deal? Thanks in advance!

Graham, thank you. What exactly do you mean by shoulder bump?
He means if the shoulders have grown from repeated firings and are not being bumped back .001- .002, then the case will not fit like it should in the chamber. Also, be sure to put a little bit of grease behind the lugs wher they make contact to keep them from galling when they lock up.
Is there a special die that you need to do this?
Sounds like you've gauled your lugs. Get a set of head space gages and just bump the shoulder back .002"
If I've gauled the lugs do I need to repair or replace the bolt or rifle?
Chances are you only have one bolt lug making contact anyways. People already have them lapped to get contact with both. So having some scratches on one isn't a big deal.
Also, what kind of sizing die are you using? A FL sizing die will take care of this for you.

You should dress off the galled area. Or find someone to do so. That will help keep it from recurring. Also, properly set up dies do not move during the loading process. Tighten the lock rings and they should stay put. What type dies are you using? Press?
[MENTION=50381]ashih313[/MENTION] yes, it is only on one side. I would be interested in having the lugs lapped, I just have no clue as to how to get that done.
I'm using Lee dies (FL sizing die) on a Dillon RL550b.
[MENTION=28909]rth1800[/MENTION] when you say "dress off the galled area" do mean, like smooth it out?

The rifle is fine. The way you keep it from recurring is not to do that again with your rifle. Anyone who gives you advice as to how much your lugs are damaged without having seen the rifle is full of it. You don't need repair work, you need only to learn how to reload properly.
^^^^^ this. And invest in a good headspace gauge.
if you are refering to a headspace gauge for the chamber you are not going to like what you find coming from remington... just sayin'
the gun is fine. the bolt head may have been scraping before you ever loaded the tight-fitting cartridges. also, don't go crazy on the full length resizing. Having a cartridge that is a close fit to your chamber is generally considered a good thing, accuracy-wise. If you push the shoulder all the way back on every reloading, you are gonna work the brass harder than necessary and shorten its life. it just requires some experimenting and experience.
Photos of the lugs and bolt will help, but, I doubt that there's any problem in that area....Otherwise, I'm with Graham...ensure that your FL die is properly resizing and bumping the shoulder back.
If you are unsure of what "bumping the shoulder back" means......... Let me google that for you

You got me Niles, CARTRIDGE headspace gauge. And I know what you're saying concerning those long-throated remingtons.
Thanks to all for your help. Here are some pictures taken from different angles, if this helps. Also does anyone know if there is a place in Florida that I can get the lugs lapped? I'd like to avoid having to pay all the fees for shipping a firearm to get this done. Thanks again!

Graham,
You say " Anyone telling you how much your lugs are damaged without seen the rifle it is full of it" You then go on to make a definitive statement about the lack of damage or need for repair, without seeing it. You are for once correct, you are full of it.
I made no such claim. Basic mechanical principals indicate removal of protruding shards of metal in any precision bearing surface. This is not an assessment of damage, just common sense.

Even if I would have believed you before, now I have my doubts about the integrity of your advice.
Your reading comprehension sucks: I did not tell him how much his lugs were damaged.
So you now say that you were simply telling him to 'stone off the raised areas' of the bolt lugs of his rifle as a common sense application of 'basic mechanical principles' and for no other reason?!

That bolt lug is galled, minorly. It'd probably be fine to do nothing, but were it mine, I'd carefully stone/hone it to remove the high spots.
Where in Florida are you?
Buy a tool that allows you to measure the case head to shoulder length of your brass, and adjust your dies for proper sizing.
Don't force cartridges into the chamber.

Had this happen to a custom action of mine several years ago. Problem wasn't that I wasn't bumping the shoulders back far enough, but excessive pressure or lack of a lug grease as I was running the bolt without lube. Had scratches on the same lug and also some damage to the lug seat if I remember correctly. Rifle went back to the smith and he cleaned up the bolt lug just a touch (can still see where the scratches are) and cleaned up the lug seat as well. This required setting the barrel back just a taste to keep headspace correctly. I also had him apply matte hard chrome to the bolt while it was there to help prevent this from happening again.
Lesson learned: use a lug grease/lube. Also double check that you are in fact bumping the shoulder back about 0.002" and you should be good to go. Most of my custom rifles now have NP3 on the bolt body and internals as an extra measure of protection.
I'd suggest having the action checked out to make sure there isn't some build up on the lug seat just to make sure. May cost a bit but will ease your mind and possibly prevent future damage to the lug.

Pinecone, nowhere in what you quoted did I tell him how much his bolt lugs were damaged. I told him that his rifle is fine and that he doesn't need repair work; I did not tell him how much his bolt lugs were damaged.
rth, You are again speaking about subjects you know nothing about, not to mention following me around for the purpose of calling me names. Kindly obey the Site rules or go somewhere else.

I think it's fine. unless you're just wanting to spend the $$ to get it blueprinted, which is ok too. the finish that they put on these factory 700's is not particularly durable, I would expect there to be shiny spots like that. if its like many factory 700's, it wasn't bearing evenly on the lugs in the 1st place.

The evidence so far is that you are being a Troll. And if you think that eighty thousand members of Sniper's Hide enjoy reading your interruptions of other peoples' Threads solely for the purpose of you giving your opinion of me, then it's not me who is acting like the delusional egomaniac.
As with your other posts, simply declaring that something is happening does not make it factual.

I'm ok with it.
One thing was said that is true...you can't tell what it needs from the pics. It may be fine but, I've seen it happen where material embedded in the lugs that continued to gouge into the inner abutments. It just got worse, not better. Felt like 60 grit in there.
Graham,
If you will review the above thread, note that I simply posted the correct way to deal with galled lugs. My post did not address you at all. Almost every poster on this thread has called you out on your statements. Yet you persist.= egomaniac You seem angered that I simply told you that you are wrong. Deal with it. YOU ARE WRONG. Leaving sharp shards of metal on a precision fitting that operates under pressure of the cocking cam is ridiculous.
I do not even have time to go over my 35 years of experience in precision work involving ceramics, metals and resins in dry and fluid environments or play further word games with you. I have been doing this stuff for years on things far more precise than bolt lugs. All while you were writing stupid shit on the internet.
I will let you have the last word, as I simply have too much to do to continue to discuss so obvious an issue.
How deep is that hole now?

Hopefully your 35 years of experience were not spent giving people advice on how to repair problems that you had never seen.
And your argument is that It is me who is the egomaniac. Brilliant.

And how do you figure telling someone the rifle is FINE and repair work is not needed is NOT telling him the extent of the damage????????
Remington 700 Bolt Lug marks/scrapes
It's not the same thing as telling him the extent of the damage because it's not telling him the extent of the damage.
It's telling him that regardless of the extent of damage to the lugs even being an issue, the rifle is fine and repairs are not needed after simply closing the bolt on an improperly sized case.
Now you just want to argue.
