I just measured several .30 caliber 165 grain Partitions I have on-hand among my reloading supplies, and they all measured exactly 0.308" on the nose.  I also miked 5 other different types of .30 caliber bullets ranging from 150 grain to 180 grain in both flatbase and boattail designs from Nosler, Sierra, Barnes, and Hornady, and all were 0.308" dia.  0.311" bullets will shoot out of a 0.308" bore, since the soft bullet deforms to fit the bore, but pressures will be higher than normal, and that's probably a big reason they wouldn't shoot out of your gun.

id say, im still surprised it didnt mess up the barrel, i realize that the copper is softer than the barrel's steel is but man i would assume it cannot be a healthy end result, im surprised they even chambered up, the pressure had to be some thing fierce, back it off the lands a few thousand's and a bullet diameter already to large for the barrel diameter and a magnum charge of powder sounds like disaster waiting to happen.

        QUESTION is,how did he end up using the wrong size bullets? His error or Noslers? The guy I mentioned earlier with the oversized .277 caliber bullets packaged his up and sent them back to Nosler. He hasn't responded with any info yet. I've got 100 .257 cal Partitions I'm gonna measure later.

I asked for .308 200gr Nosler bullets from the gundealer. He sold me a box clearly marked Nosler 200gr .308 cal. So no, the mistake is not mine or the gundealer.

I do not own a sophisticated dial micrometer, so it is not impossible that I measured incorrectly. I will check them again, also against other bullets I have.
 
The rifle did not show undue pressure.
The question is, is a barrel diam measured from groove to groove, or within the groove spacing. In other words should a .311 bullet fit between the grooves.
But before too much is said, let me re-check the diameter of the bullet at some engineering works.
My own micrometer is a good quality sliding type marked in mm. I have to be able to read the difference between 7.82mm = .308 and 7.9mm = .311. This is not easy on my micrometer.
 
So please, hold your horses, spare my feelings and I will report back with another reading.

       8shots,PLEASE don't take anything I say personal cause I'm not that way! My main concern is that if Nosler is having a problem with correctly sizing their Partitions or are putting the wrong bullets in their boxes I'm sure they would like to be told.  If your bullets turn out to meas .311 then yours would be the third incident I've seen on line. What concerned me with the group you shot with those bullets was how WIDE it was. Sure,some rifles don't like some bullets but that looked like a shotgun pattern!  Although you had no pressure problems with your rifle one with let's say a minimum chamber with a tight neck area firing an oversize bullet would more than likely be a different story. Anyway,hope we get the cause of the problem solved soon.

300S&W, I was also just joking. Lay it on, I can take it on the chin.....
 
I have taken the bullets to an engineering works where they used a more sophisticated micrometer to measure.
Nosler = 7.8mm = 0.307 inches.
Sierra Matchking = 7.81mm= 0.30748 inches.
 
The Noslers are in fact the correct diameter and I humbly apologise for my earlier incorrect information passed along.
 
Sorry

 You guys probably won't believe this, but I was present when an otherwise competent rifleman made a very careless mistake at the range a few years back, when firing his Remington 700 from the bench.  It was a .30.06 with a 22-inch factory barrel, 1-10 twist.
 He set up and fired a fairly rapid 3-shot string, and was puzzled about the unusual muzzle blast or something.  I forget what tipped him off that something was wrong.
 Turns out he was shooting 8mm (8X57mm) Mauser cartridges through it. 150 grain Hornadys, I think they were. The bullets for the 8x57 Mauser measure .323.
 The rifle was unharmed, but thank heavens it was a Remington 700.
 If I recall, the group he fired wasn't bad at all!
 He'll never forget the chewing-out I gave him, either!
