This may be a dumb question, but if I buy factory new brass, say Starline 44 mag, do I need to resize it?

Generally speaking, Starline cases require no resizing prior to loading. Due to variances in diameter of different bullet types, it is a good practice to size the case only as far down as the bullet seating depth. When full length sizing is required, it will be noted in the box with the brass. The only Starline cases requiring full length sizing prior to loading are the .454 Casull, .458 SOCOM, and sometimes the .45 Colt(Depending on the bullet diameter to be used).
I haven't and maybe I'm missing something, but why should I when I can measure the brass that comes out of the die?Also, as a matter of curiosity, how many who claim they run new brass through a full length sizing die have actually made a casting of the die and checked and confirmed its dimensions?

Not only do I resize but I also run a neck brush through it and lightly chamfer the mouth. Some new brass is pretty sharp at the mouth and can scrape the bullet as it's being seated.
Amen - Winchester brass was the worst for me with needing to be trimmed right from the get go, .223 and 7.62x39mm.Treat the new brass same as the old brass: clean, resize (or at least neck size), and trim to a standard overall length.
This statement contradicts itself, new brass isn't reloaded, as reloading occurs after brass has been previously used. Perhaps the poser is referring to commercial reloaders like Black Hills and others who do of course have a sizing operation for recycled brass before reloading. As to main ammo manufacturers, I've seen many thousands of rounds loaded at Federal, Remington and Winchester, plus some European firms, and the cases are loaded as they come from the shops where the brass cases are drawn and formed.If you look at the big commercial reloading machines the major ammo manufacturers use there's always a sizing station early in the process, and they're using new brass.
