I ran into the same problem myself. Couldn't find any Remington or Winchester 7-08 brass anywhere, so I bit the bullet and paid big bucks for some Nosler brass. Nosler claims this brass is ready to reload out of the box with no prep needed. Well, that's not exactly the case, as half of the rounds I reloaded would not chamber in the rifle. I will resize the cases completely when I get back to reloading them. I have reloaded a gazillion rounds using new Remington or Winchester brass and the only thing I do before reloading is to inspect them and if the neck looks like it needs it, I will run it in the die just far enough to straighten out as needed. Having said all that, the last time I checked, Midsouth had some 50 round boxes of Nosler brass, if you need some.
