    hi my name is Curtis Keller I am 12 years old, and I have a 257 weatherby in a remington model 700 sps stainless. I have been reloading for it and I have been having issues with the brass going in hard after about the fourth or fifth shot with neck sizing. My bolt face also collects some brass on it too. I have tried full length sizing after shooting the factory norma brass once and that just makes it go in hard too, but then I can shoot it and it goes in easy until the fourth and fifth reloading then they start going in hard again. This gun has no problem with shooting 1/2-1inch groups at 100 yards.

    Welcome to the forum. Are you trimming the cases to length
    as part of your reloading process?

    Your dies could be the problem also.
    Try loading a new unfired case in the rifle.If it goes in easy,then resize it with your dies,and try it in the rifle again.If it is hard to close the bolt,you might need some new dies.

    It's nice to here from a young man that's into reloading.Who taught you how to reload?

    Also,if you are loading older brass,it probably needs the necks annealed.I anneal all of my bottleneck cases every 5 firings.If you don't,the brass gets hard and won't resize properly.That will also cause the problems that your having.

    Ya I suppose that the dies could be the problem cause it is doing the same thing in my dads gun,but I have a neck sizer die that after 4-5 reloadings my brasss start goin hard and the fifth shot in my dads gun split the necks with neck sizing. My dad and my uncle taught me how to reload cause they have have been doing it for a long time.They do not know what the heck is going on either.What is annealing. I tried that taking a new brass and running it through the full length sizer die instead of the neck sizer and it goes into my gun good

    Anealing will extend the length of the cases. Brass work hardens. Anealing corrects this.

    anealing is slightly heating the neck up to a certain temperature, not sure of the temp, to soften the brass a little. they make some tools to be able to do this with a propane torch. i think Midway has a set of tools to do it with for different size cases.

    Thanks to you guys I figured out the problem and the thing that I have to is after the first shot I have to full length resise and then neck size and i get 7-8 reloadings out of it then.

    just a suggestion and some info, bottleneck cases will need trimming more for OAL than straight walled cases and check your OAL after every firing of the case. sometimes, the hotter the load, the more the case can stretch in length.
