Another Neck Splitting Round?

Discussion in 'Handloading and Reloading' started by PCCUSNRET, Jul 31, 2010.

    Just got a chance to try out my new (to me) Remington 700 VLS Varmint Rifle in 22-250. One of the local K-marts had 12 boxes of Winchester on clearance for about $13.00 a box and it just drove me nuts seeing it setting there every time I went in the store. Anyway, found what I think was a pretty good deal on one of these guns and bought all the ammo they had on sale (I even posted it here hoping someone would buy it before I broke down:eek:. I shot a box and a half of this ammo yesterday and the gun is probably one of the most accurate guns I own. At 100 yds these store bought rounds were touching for the most part dead center. About 4 rounds into a 5 round group one of the bullets would drop below the group about an 1 or 2. After examining the brass, I noticed the neck was split all the way down the shoulder. Out of 30 rounds, 2 had split necks. I had hoped to use this brass for reloading since it was now fire formed but now I'm wondering if annealing would help prevent the others from splitting. Any suggestions? They sell used brass at our range but when I asked if they had any 22-250 I was told it all had split necks so they don't offer it for resale anymore.

    Well, neck annealing certainly couldn't hurt anything, and it might help.

    It could be just bad Winchester brass though.

    It can also be caused by an over-size chamber neck in the barrel.

    If I were to measure the necks of the brass that I just fired in this gun would it give me the actual size of the chamber neck?

    No not the actual size.

    The fired brass will spring back after firing to a certain extent.
    How much will depend on how soft the brass is.

    I don't understand or must be missing something. You are using the proper ammo in the proper rifle that is chambered for that ammo. And, the necks are splitting. Am I getting this right?

    I would take the gun in to a gunsmith and make sure the chamber is correct before I fired another round.

    If the chamber is off, I'd take the gun back. If chamber was good, I would be getting really nasty with the ammo manufacturer.

    The really simple test is to buy another brand of ammo and try it.
    Maybe try Remington ammo this time?

    When I shot & reloaded a lot of 22-250 years ago, neck thickening and splitting was a common problem.
    Annealing and neck reaming solved it.

    I'd almost be willing to bet the problem is with the K-Mart clearance Winchester ammo you are using though.

    Normally I'd say just anneal it. But I think I'd try some Remington or whatever other brand ammo you can get first. The rifle is the most expensive part so it'd be good to know it's ok.

    A fired case neck diameter should be about .256" - .257" This is based on the loaded rounds maximum neck diameter of .254"

    It seems like that to me too. There's probably no safety issue, and by selling the ammo at clearance, chances are they don't have to worry about a recall or replacement and it gets flushed out of the system.

    Thanks, they are .255.

    I really don't believe it is the gun as only 2 of 25 pieces of brass had the split necks. I'll try some Remington and see if that solves the problem with the brass.

    I'd still like to have the recipe for these Winchester rounds to try in another type of brass.

    Well I tried 2 different brands of ammo today, Privi Partizan and Remington and the necks didn't split on either of these. I then tried another box of the Winchester and none of the necks split out of that box. I think it must have just been a couple of bad pieces of brass as this gun was even grouping the Privi at less than 2" at 100yds. Thanks for the help.
