Ok. I based that off the ones I have worked with. The die had to bump the shell plate or there was to much head space.
Rem 700 in .308 issue with bolt closure

Well I adjusted the FL sizing die 1/4 turns and chambered the brass until I had a good closure. The length wasn't an issue it was the shoulder of the brass. I'll load up a few and be sure cartridge length isn't an issue before I go wild reloading.
Thanks for all the help.

When that happens to me AND the cases used to fit fine, it's almost always because I didn't trim my brass before reloading. If I changed the oal by seating longer bullets, then it's the bullet contacting the lands.

Tight reloads in new rifle
Sounds to me like you have reloaded shells that the brass had been fired in another rifle (since yours is new) and they have expanded larger than your chamber. Cases will have to be full length resized befor they will work in your chamber. Al

Wow, As I'm looking at threads in this forum imagine my surprise when I see someone has the exact same problem I experienced this last Thursday at the range! I had the same problem closing the bolt on some of my reloads. I talked at length with one of the range officers who also teaches the reloading classes there, and he said that it was probably case length and to NOT crimp! He told me crimping causes more case stretch.
When I got home I used my calipers on the cases and sure enough, they are measuring more than the MAX case OAL of 2.015". I have a case trimmer on order now and have some work to do when it comes in!
I'm also going to re check my sizing die and make absolutely sure it is set up to take ALL of the flex out of the press for a complete FC sizing!

Guess what? Remmy factory chambers will accept cases as long as 2.025". Case length is not the problem. Improper headspacing is the problem.
People need to take time to understand the internal geometry of their firearm before assembling ammunition.

The High Road....I love the friendly responses that come from members of "THR"....Criticisms for having problems and asking questions seem to be the norm. Been on this site long enough to spot the ones who are helpful and those that post just to berate. I apologize for posting on "your" forum and trying to get answers. I know of other forums where people actually do take the "High Road". Maybe I'll just stick to them because they care more about passing along knowlege than berating someone because they asked a question.
Funny thing though, out of the 35 rounds I fired (my reloads) only 5 wouldn't chamber. Being as I reloaded them all at the same time, deprimed and resized etc., it's funny that they would have "head space" issues while the others didn't. I know, I have a set of faulty dies....better throw em out! Thanks for playing!

If you are using mixed brass, it is possible for those that have been reloaded several times more then the others to be harder.
Or for a different brand of brass to be harder.
As such, the softer cases will resize properly at the current die setting.
And the harder ones won't.
Either would require a different sizing die setting to push the shoulders back to the same degree.
The fix is to sort and size in batches of similiar brand cases that have been reloaded about the same number of times.
Or neck anneal the whole bunch and treat them the same.

I'll check the headstamps on the mystery "5" when I get home. Thanks rc for the help.
BTW, is there a difference between Military brass and civilian?

Yes.
Military 7.62 brass is both heavier & thicker, and probably harder then commercial .308 brass.
It also has less case capacity, so work up to max using it.
Then you should be O.K. with the same load in commercial .308 cases.
PS: The 7.62 cases have crimped in primers.
You will have to remove the crimp by reaming or swaging before you can reload them.

Update....all 5 headstamps are military. 4 were LC 88 and one was LC 91 (LC=Lake City?). The case lengths for them were as follows...2-LC 88 measured 2.026", 1 was 2.028" and one was 2.029". The LC 91 case was 2.029".
By your own statement, these cases are too long for my brand new M700. Just to make sure I wasn't wrong and had mis-adjusted my resizeing die, I ran them through it. Other than the resistance from the depriming pin knocking out the primer, they fit fine and there was no resistance (properly lubed).
I'm NOT looking for feelgood comments much like I'm not looking to be talked down to. I'm looking for reliable information from MANY sources including the people outside this forum!
"People need to take time to understand the internal geometry of their firearm before assembling ammunition." was not constructive or informative so I took offense especially because it appears that my Rangemaster was correct. Sorry if this isn't what you wanted to hear from me....
Wait a minute.
Are you measuring the case length of a loaded round with your dial caliper?
That is not how you get a precise reading.
Just how many times did you reload that brass. In my experience it takes five loadings to stretch a case to 2.029".
Are the case mouths scraped up by the chamber? They should be if that is indeed the problem.
Or maybe it isn't.

Pulled the bullets, emptied the powder, measured the cases. I've had this brass since about '93. This was range brass from the gun range at FCTCLant Dam Neck, VA (home of team 6). They were once fired when I got them BUT, I never kept track of the number of times I reloaded back then. They were only used in my FR-8 with reduced loads because the FR-8 has been a question for debate when it comes to "factory" loads. This brass could have been reloaded 3 or 4 times but the FR-8 never gave me issues with any cases being too long. The case mouths aren't scraped up because I didn't force the bolt closed. I probably could have, but when the bolt didn't close the way it did for other rounds, I stopped. The cases show no signs of cracks or other defects so I'll trim them down when the case trimmer I have on order comes in...should arrive this week.
I also did random case length checks of my other empties and they are averaging 2.012" to 2.015" so I'll need to keep track of them or better yet, trim them to a uniform length and keep track of them.
918v, I want to appologize for my conduct on this thread. I was frustrated and because I was at work, couldn't go out and do the checks as quick as I wanted. I hope that we can put this behind us because I depend on all of you out there to provide information when I run up against something I can't explain. Once again I'm sorry!

Call me a Richard.
Call me an Adam Henry.
But don't say you're sorry!
Now you're making me feel bad.
Take your longest case, size it with the expander plug removed, then try to chamber it. If it's the case length, you'll feel it. If the bolt closes, you know it's not the case length.

Once again at work...Have to wait til after 5 to try that out. Thanks!

Ok, I tried the "5" in my gun and got the bolt to fully close. After removing them, I noticed the case mouth had an area where it looked like it caught on something and pushed the brass back slightly (I'd take a pic but don't have macro on my iPhone). Don't know if that was what you wanted to find out or not.
