new brass

Will on kauai

hello silly question you need to resize brand new brass ?[:)]

MIKE WISKEY

in general...yes....also chamfer the case mouth

Sometimes. Depends on your chamber and the brass. Quality control isn't all that good these days, lots of dented necks.

Generally I fire form new brass with a cast bullet. After that it's neck sized, trimmed to uniform length, champhered inside and out. I also de-burr and uniform the flash holes.

I've always fl sized new brass just to make sure everything is right.

Your question was, do you need to resize new brass? The answer is no. After all, new brass is what the manufacturers use to produce factory ammunition.

At worst, if there are a lot of dented necks, you can run them over a mandrel or button. But even that is not necessary if you are using boat tail bullets or any other bullet with a rounded base.

The Internet has spawned a new generation of shooters who believe that 10 or 15 steps have to be taken with new or fired brass before it is suitable for the average plinking or deer-hunting rifle. I am a Benchrest shooter and I do most of these things to my Benchrest brass but I confess that only one or two of them really make any difference.

Shooting used to be a lot more fun and a lot less work. Not that there is anything wrong with turning necks, uniforming primer pockets and flash holes, chamfering, annealing necks, weighing bullets, adjusting seating depth to the nearest thousandth, etc, ad nauseum. If it makes you feel good, do it but don't expect miracles.

End of sermon.

I disagree ,when I get new brass I resize.
check the trim length (sometimes I have a
lot of trimming to do)then Chamfer inside and out

I have never resized new brass, and never had a problem with it. I reload .223/5.56, .308/7.62, .30 carbine, .38 spl, .357 mag, .45ACP, .44 spl & magnum, 9mm. That would be like resizing new live ammo you just bought since its the same brass.

Have you ever miked the new brass for length?

Will,

For your best results, do everything, as suggested by MIKE WISKEY. If you are loading for a lever, pump, or semi-automatic rifle, I also suggest using a set of full length, small base dies.

Best

just load one in the rifle, see if it will close and eject, I do this even after resizing just to make sure it will chamber, in my pump and lever action rifles.

Maybe. As says, depends on quality. I got a batch of brass once that the necks were all too tight, and the bullets bulged the necks... had to pull all the bullets, dump the powder, deprime, resize, and reload.

Doing that to a few hundred convinced me to just FL size new brass as a matter of course.

I bought 500 rds of Grade 1 .223 brass
(I know it's not new brass but I had to resize
and trim every one.
I'll say it again, new brass, I resize every piece
and "mike" for trim length.All it takes is one and
a low end tol chamber for a shower of molten brass.
