New Brass Prep

[Surculus Solitudo]

I will be using some new Winchester .243 brass to reload with. The Lyman manual says I do not need to size new factory brass. When I was inspecting the brass, I noticed some of the necks were not completely round so I am wondering how good the quality control is on the rest of casing. I am thinking of running the brass through the sizing process even though they are new.
What do you think is proper case prep for new brass? Thanks!

I always size new brass to ensure it's uniform. If your brass was packed in bulk, it took a beating in transit. It has nothing to do with quality control at the factory.

Hope this helps.

I do the same as Fred. As a novice reloader, I just loaded them w/o resizing. After I got a chronograph, and better scopes, I tested the difference. The new resized cartridges had better Extreem Spreads, and were slightly more accurate.

I don't size new pistol brass.......BUT I do at least neck size new rifle brass.

Powder is too expensive to waste when making rifle ammo that may be less than perfect.

I do the same thing. If it is rifle brass I treat it the same as once fired. They take a beating when they ship them as bulk, and it isn't that much trouble to make them all the same.

MY new brass (when I decide to treat myself) gets sized, then trimmed, THEN loaded for use. My infamous saying "If it ain't accurate, it don't count"......

I always fls new brass as well, mostly to iron out the dings. I also do all of my other brass prep (uniforming everything like flash holes and primer pockets) except for trimming (unless its excessively long).
After I have fired the brass once I trim it.
That's only for rifle brass, I've never bought new pistol brass. I just use stuff I policed from the range.

the thing that makes f.l. sizing new brass nice is you won't need to lube it. really all you're going to do is take all the in-transit denting out...

Depends on you

No sarcasm here. If you don't care about picking up the last half-inch of accuracy or consistency, then don't bother. You shouldn't have any problems feeding your gun and, if you do, you'll know soon enough.

I personally think you should resize. It's easy and you already have the die, so what's the problem? The reason to do it is a more consistent case and, therefore, more consistent group.

I don't differentiate between new brass or old brass. I load them all the same, using the same steps, etc. I prefer to be a creature of habit.

Winchester and Remington bulk brass is always banged up and needing some cleanup. I do a full prep: f/l size, trim chamfer debur necks, primer pocket uniform, flash hole debur and clean out trimmings with neck brush. I stop short of shaving necks.

Norma and Nosler: I just checked a few and started reloading.

Call Sinclair International and purchase a neck mandrel die.

It's a very valuble tool for getting all your case necks nice and round without stretching them out like the pivot man at the prison shower.
