    I have a savage model 10 brush camo. I fired 1 box of 50 gr, 1 box of 55 gr, 2 boxes of 45 gr Win factory ammo. All of them grouped .75 to .5 MOA at 200 yards. I neck sized all of the brass with an RCBS neck sizing die set. I grabbed my Hornady head space gage and started measuring. After a few readings I measured some of the new unfired Rem ammo and some new Win brass still in the bag. What a mix of confusing numbers.

    Results..

    Rem new ammo 1.562
    Rem fired & neck sizes 1.564 ( kind of expected)
    Rem oal 1.909

    Win new brass 1.560
    Win fired & neck sized 1.567 (not expected )
    Win oal 1.910

    The Win fired brass that I neck sized will chamber with force, it's very tight. The Rem neck sized chambers just fine. Anyone else have a similar problem or seen this much difference in expansion?

    I shoot both brands of brass in my 22-250 striker pistol, and both are just fine. I never neck size though; haven't needed to. I hunt with my rifles and cases getting sticky in the chamber means you have a rather expensive baseball bat when one one finally sticks, until you get back to the truck for another rifle, at the very least.

    INTERESTING.... I would try setting the shoulders back.002 using a redding body die. That should match you chamber better and allow better chambering. If all brass (rem and win) are done together reguardless of brand you should expect the same results of consistency.

    Maybe I am completely wrong or maybe I know from experience. I am sure some will agree and some will disagree time will tell. Hope this helps. That is my intention.

    I will have to bump the Win brass so it is usable. I have never had a problem with neck sized only brass. I didn't expect to see one expand .003 more than the other out of the same chamber.
    I was thinking that that the Win brass might be softer? or it stretched a little when sizing? the only problem with the second senario is out of forty cases they are all pretty much the same size. Within .0005 to .001 of each other.

    Probably different pressures for the ammo.... A lower pressure load will often swell the brass less in the same chamber. The steel in your gun has a bit of give; enough presure difference and it can be noticeable on brass, etc..

    I fl or partial fl size everything so I don't have chambering issues. Neck sizing can be done if the brass will fit the gun well, but if not you have to either use a body die or fl size otherwise.

    My experience with Winchester brass has not been good, especially in the 300wsm. After 4 firings it was trash. I later read that Remington and Norma were the better routes to go. So for the 22-250, I went with Remington. I couldn't be happier. It's been consistent and I have some very good accurate loads that developed quickly in my savage LRPV. I won't use Winchester again. I use Norma and RWS in my .308.

    I've never had any issues with win brass other than shallow primer pockets. I've got a couple of thousand winchester casings in various cal.s here and they are all fine. I'm sure they've put out a few bum runs of brass; they all do. All in all though, rem and win are usually your best value in brass.

    My cousin and I both experienced neck tension issues after annealing the Win. brass. You would go to seat the bullet, and then the bullet would drop right through. He bought his Win brass a couple years after I used it. Never had a problem with anything else after doing the same annealing process. I know there are a lot of guys that use it. I must have just gotten bad few hundred casings.
