Chambering Problem

[Rule3]

It is all about your sizing die and if it is set correctly to set the shoulder in the correct way.

The easiest way is to use a Wilson case gauge.

Plunk it in and you will see if you need to "bump" the shoulder up or down.

Once you have them set correctly you can get by with just neck sizing (for a few times) in a bolt action. Eventually they will need full sizing again. If neck sizing you do a lot less trimming.

I gather it is a 308??

Yes, you can get by without a gauge but it makes life much easier and you avoid these pesky issues.

I trim all my 308 brass to exactly 2.000". Just as easy as doing it to 2.005" I have had problems with some rem factory brass. Hard chambering due to the extractor cut not being cut properly.I never had that problem with U.S. National match,match,or just plain old G.I.Ball. Ogives can vary from bullet to bullet even in the same lot of bullets. Lets say you bought some Sierra 168 matchkings.I have one of those gizmos that would detirming the same point on the ogive on the 168's. Things like this tend to follow a bell curve if you were to draw a graph. Most of your most consistent ogives would be in the middle. Back when I shot a lot of 308 Sierra just had the tips of the bullet finished as they came out of the dies. Then someone came out with a meplat turner which worked on the bullet tips. Now Sierra has added a polycarbonate tip to elimnate all this foolishness. To give you an idea how much 308 I shot I was buying 168's matchlikgs in 500 round lots. I was keeping careful records with # of rounds fired, load data and temp and humidity. No mater how far out I seated those bullets I could never touch the rifling. That sendero has about 1400 rounds through it. Then I got a savage 110FP in 308. Still had problems getting decent accuracy. But it was stock related. Had to glass bed the front receiver ring and recoil lug as the whole action was moving each shot. Buddy gave me ten rounds of his handloads on match cases. 10 shots 3/4" at 100 yds. That target is in my records. I have a 40x singleshot in 7.62nato. But haven't had the time to wring it out like the other two rifles. This rifle has a very heavy stainless barrel 26-28" long.And laminated thumbhole stock. Frank

Ah, I have a question..............

Did we ever find out if the weapon in question was chambered in.....
308 or for a NATO round ?

No, the OP never even mentioned the caliber but we are clairvoyant.

I know a guy who shall remain unnamed (no not me)that had a problem in a semi auto like this. Seems he was crimping to hard and that pushed the neck down and thus the shoulder. I know the op said he is not crimping but if a empty brass fits and loaded one does not, well ????

But the Rem 700 it doesn't matter what brass 308 Win or 7.62 x 51

It makes no difference whether the brass is 7.62 NATO military or .308 commercial for any rifle, insofar as utility and chambering are concerned. The cases are fully interchangeable. There may have to be charge adjustments necessary to reach identical MVs, military vs. commercial. And some military cases may require primer pocket reaming or swaging to remove the crimp. Some of the finest and most consistent brass I ever used was Canadian military.

Overcrimping and distortion of the case shoulder area is something most reloaders will experience at some time. That's why I have never crimped .308 unless I am using a bullet with a cannelured jacket. And sometimes, not even then. I mentioned that in posting #16.
