Looks like those Federal cases have been reloaded a few times.
I’d clean them up a mite with a file, and load them ‘til the primer pockets expand . . . .or necks split . . .which ever comes first.
The nicks in the rim look to be caused by the extractor snapping over the rim upon chambering.

^^^^^^^^^^ THIS ^^^^^^^^^^^

 

Pull the bolt and check the bolt face for damage, dirt, crud. Make sure the extractor is working properly. If those hulls didn't look like that going in they shouldn't look like that coming out.

 

Like said above, those are Federal cases and probably reloaded and put in that Remington box. I've seen chips like that before on other people's handloads that are way too hot. Were those cases easily extracted from your chamber, or did you have to really work to get them out?

 

Easily extracted

 

Are you sure the cases were not that way before you shot them? If not I would check the extractor for burrs to cause the gouges. Checking bolt face and extractor are good advice.
Have a great day.

thanks to all the replies. I'll check bolt and extractor next.

 

I don't think the primers indicate a hot load and the cases don't look that bad to me. If they are reloads they might not have been fired before in that Marlin.

 

They were certainly not fired from my rifle before. I bought both separately.

 

Curious.

If those burrs, nicks, notches--whatever you want to call them--were from your shooting session, I would expect them to be bright and shiny, not darker like the rest of the case. The color of those cases, and the price on that box put the manufacture data back into the 70s or 80s at least. Brass doesn't age that way overnight. (sticker 11 05 80---1980 stock date?)

I vote that they were that way when you shot them.

Do you have any left from that box to examine that you haven't shot?

Yes, those rims are chewed up, but the brass is still usable. I've got no good explanation how they got that way. They almost look as if sometime in the past, they were cycled through an action and ejected onto rocks or another hard surface. But I wouldn't think that every one in the box would have been.

Can you post another photo or two of the bases of all the rounds you have from that box?

It appears you were correct. Pics above. Thanks!

 

I'm going to bet that those were caused by an extractor that has a burr or is a little sharp. It was either yours or whoever shot those before you. They shouldn't affect your ability to reload them. If it was my gun and everything was working normally, I wouldn't go chasing it just yet. Try shooting it for a while and it might go away as the gun wares.

 

YOu were correct. Due to advice here I double checked some unfired rounds and found the FC headstamped rounds were indeed dinged up prior to my rifle. They did fire just fine so I'll reload them and be back in business. I uploaded pics to this thread too. They're older than me! Cool! Thanks!!

 

Alot of good information here thanks to everyone. Attached are pictures of the bolt and extractor which I think, look ok. The extractor does not sit flush with the bolt in its housing, and there may be an ever so slight burr or nick on the bolt just above where the extractor sits near the top of the bolt face. I tried to get pictures best I could.

what say you?

 

Indeed it appears these were reloads and the Federal (FC Headstamp) rounds were marred long before me or my 336 A. The Remington-Peters (RP headstamp) rounds look ok. Thanks to all. Good info here. I can report the rounds fired without an issue despite their age and their condition.

 

The primers on the FC rounds look a lot less tarnished than the rounds they're in unlike the RP cases/primers which look pretty evenly tarnished. No telling what they were fired in. If the brass is in good shape otherwise I'd clean the burrs off and reload as long as I could.

 

good catch. now i'm wondering if the RP rounds were factory given the old remington box and maybe the FC were the reloads. No way to know. Just glad I can still use! Now I just gotta find some primers and powder!

 

Glad it all worked out. I, too, would have recommended cleaning them up a bit and reloading them.

 

All good info here, a sharp edge on the loading gate can also cause a ding in the rim like that, one of my rifles was doing that, I massaged the front edge of the gate and it went away.

 

Glad it's not your 336.

Not sure what you mean by the RP primers being tarnished. RP primers are a old brass color out of the box. Feds, W-W, and CCI are nickel colored.

I think you're correct that the Fed cases have been reloaded and the RP rounds are factory. Those three Fed cases look to have brass colored RP primers in them--unless it's the lighting.

Are all the primers in the F-C cases nickel colored or are some the same color as the R-P case primers?

Anyway, I think you figured it out.

 

I have been reloading since 16 years old off and on. At first learning how with my godfather 50+ years ago. I have loaded and used old ammunition boxes over many times. I probably have or had a box or two with mixed head stamps. It looks to me the box of ammunition you bought are no doubt reloads using federal brass in a Remington box. As already said does gouges look tarnished, did you inspect the those rounds before you loaded them in your rifle? I also think if those gouges were made by your rifle and you noticed it right away, they should’ve been shiny.
On a second note. You are very lucky you have fired someone’s else reload and all you have to complete about-is gouges on the rims of the case.

 

I also think if those gouges were made by your rifle and you noticed it right away, they should’ve been shiny.

There ya go. The fact that they aren't shiny, or at least don't appear to be, would indicate they were made by a different rifle some time ago. You have some rounds left, inspect them for gouges and fire a couple and see if it happens to them.

 

This Thread has all kinds of possibilities that can make gouges in a case rim. One more thought come to mind is that the previous owner could've had a Remington Model 8 or 82 semi-auto causing the problem.
