To rephrase the statement
I might say why would a perfectly good hand load that fits in a chamber gauge
Not fit in the chamber of a Rifle of a factory configuration?

If I was shooting .5-.6 at 200, I would not chance wrecking a barrel
like that, By sticking a reamer in it with no knowledge of original
chamber dimensions. Case guages can fool you easily.
When reloads don't fit, something is not compatible with
the dies your using, or they are not adjusted correctly. I have no doub't
that someone in your area can get you on track, with little expence.
What I would really like to know, is how do you shoot 44gr of varget
and 155 bullets, if you can't get them in the gun.

Jim:
Have you thought about making a cast of your chamber and spec it out.
It is easier to remove metal than to put it back.
It sounds like your rifle shoots pretty well.
PT&G makes chamber, throating and necking reamers.
Also most custom smiths polish chambers and open up areas that may be tight.
It has been my experience gas guns operate loose in comparison to bolt guns.
The web area of a SAAMI spec 308 chamber is gonna be .468.
It is comon to see semi autos running .470-.472 in the web.
The chamber can be both polished and reamed from the tenon end with the barrel removed from the upper. I don't recomend pull through reaming for guns that the barrel can be easily dissasembled.
There are some very fine gas gun smiths an don't kid yourself they can shoot very well.
Your loads can be tailored to your gun easier than your gun tailored to your loads.
I own a DPMS and they say if you shoot anything other than factory loads you void your waranty anyway.
Good Luck

The problem is the round just will not chamber. It is just short of closing.
And then that round is stuck!! It will not go in or out. And getting it out,, is a fight.
The comment that the dreamer used in production may have lost tolerance. At the factory.
That is in interesting possibility.
As for re-reaming it,, at the moment I’m waiting. Until I get the small base sizing die..
I’ll load up some rounds, and see what happens.

A couple of questions...
How much are you bumping your shoulders? Have you compared diameter measurements of your fired and FL sized cases? Can you insert a bullet into the neck of a fired case?
Another thing, Lee FL dies are made to SAAMI max. for ammunition. Not all regular FL dies are. While this may be a good thing for a bolt rifle, it may be counterproductive in a semiautomatic.

You say you were using mixed brass when the problems occur? I once had the same problem when using military brass when reloading for a .308 Winchester chamber. Chambers and necks vary and the military brass sometimes has a much thicker neck wall than factory brass resulting in oversize rounds that will stick in the neck region when chambering. Be careful if this is happening as the pressures can go up quickly with the brass having no space for expansion. Check the neck diameters on reloads of various brass types and see what you get. If that's the problem the only solution is to remove brass from the neck by either reaming or turning or just buy new factory brass. You may have a minimum diameter neck with maximum diameter brass.

With mixed brass,,, and Hornidy Match brass,, same problem,, with all brass,,
I have neck trimmed and turned,, both,, it helped some,, but did not fix the problem,,,,,

I have not tried to ,,, insert and bullet in a fired case,,,
Bump the sholders,,, ? I'm guessing you mean, do I size it all the way up in the die?? Yes I have done that,,
I'm waiting for the mail man,,, to bring the SB re-loading dies,,, I don't know if I like a kid waiting for Santa,,,
or waiting for a poor reportcard to come in the mail...
I sure do want to come up with a fix for this problem..

When the time comes, start with some once-fired factory, commercial brass shot in your chamber.
Full-length resize with the new dies, load and give it a try.
My thought and, reading between the lines, is that, for whatever reason, your previous dies/setup were not sizing the case enough.
If the new setup doesn't work out, give a shout.
Don't get wrapped around the axle with your chamber gauge. Right now, it's a variable that needs to be eliminated while debugging.

Basic Easy Fix...
1....Small Base Body sizing die (does not size the neck)
2....Type S neck sizer with several buttons to get nominal neck tension for best accuracy
3....New Lapua brass
You don't have a chamber problem you have a reloading die problem, and you need a knowledgable mentor to work thru the problem with you(face to face)

The fix
I got the Small base die yesterday, I used the die on all mixed brass,,trimmed the brass, hand fed the cases in and out of the rifle chamber, then loaded them,, again hand fed them in and out,,
I just an hour ago,, shot them,, they worked perfectly!
the small base die ( Redding ) did the trick,
Thank you all so much,,, you just don't know,, (or maybe you do)
Now to work up a good 175 SMK load that will go 2600 FPS,, in an 18 inch barrel, using Varget!!

more info,,,
You guys are too good!!!
A Buddy of mine,,, found this post,,,, great info,,,,
http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=1520819&nt=2&page=1
Not all dies are equal..... disturbing,,, in a way,, But it gets closer to the info I was looking for...
That being what are the dimensions of the reamers? Trying to get that info is hard,,,,
I don't need it now that my gun runs,, but I am very surprised, that the dimensions,, info is so guarded,?? or that people, (the companies I have called and or e-mail don't know) Or just will not tell you,,
I do know I will never buy a regular full length sizing die again, I will go Small base from the get go..
I did more testing,, with ammo loaded with the small base,,die,,
And got a 1 inch groups at 200 I'm happy with that,, the wind was 10-15 and I'm shooting a 1.5-5 scope, with .5 click adjustments. Shooting prone from a bipod.
More than happy for a 3 Gun rifle.

DPMS Says it's a 308
First, I have a question, what is a 3-gun competition? I am not familiar with the term.
Next, according to the DPMS website, your rifle is chambered for the 308 Winchester. 7.62 Nato is a different cartridge, and probably not good to be used in a semi-automatic designed to work off the gas pressures of a 308.
What are you trying to accomplish by running a reamer through a finished chamber and barrel?
I would be interested in knowing.

He's not planning to recut his chamber any more. We got his problem taken care of with a set of dies.

waste of good brass if you can afford ok....a small base die is not required. i shoot two ar10's( real armalite) and neither has more than enough sizing to function.....not full length nor small base.
question anything you see in print on the net!
size to fit your rifle and its function.
guys shooting m14 and clones swear by fl size and throw it out after 3 firings....i cannot afford to throw away good brass. dont over size like they do, size to safely funtion in your rifle and enjoy the life of your brass....
life is good

All I know is that the gun NOW,, runs,,
DPMS,,, tells you to only shoot,, Factory ammo,,,,
WHO does that????
I shot it in a 3 Gun match last Saturday,, I took 7th out of 49.. only 3 of us shot a .308.
What I now know,, all guns from different Manufactures,,, Have different
chamber specs.......... FACT.. My buddies,,, FAL... will feed anything,, probably a 20Ga shell,,, HAHAH it is so,, loose,,
So if your FN, HK, M1A, Rem 700.. works with this or that ammo,,,
that means nothing,, when it comes to my gun..
