Resize New Brass?

[fishnbob]

I just signed on and I'm sure this has been hashed over many times. I usually create my own brass by shooting it up but I have bought a couple of new caliber handguns lately and when I went to buy ammo, there wasn't any of what I wanted, so I bought brass, lead & primers and then realized I didn't know whether to size new brass or load light & shoot. What do you guys do?

i've never sized new brass.... never thought much about it but it might make a better reload.............

I like to resize my new brass makes all the mouths of the cases round and they should fit in the chamber.

Just a quirk I picked up!!!!!!!!

Welcome to the Guide fishnbob.

It never hurts and might help. Sometimes brass comes with dents and abused necks. Some rifle shooters will neck size all new brass to save the time and effort of lubing. With handgun cases, the belling die usually straightens the necks out just fine. Many will also trim a batch of new brass to insure its uniformity for crimping. At minimum, I will chamfer and deburr new cases, and I will size them if it looks like they need it.

i usually back out my sizing die with new cases and neck size my revolver brass too.
if it's for a pistol it gets sized no matter what.
for rifles i size then trim [for max length] cut and whittle it down inside and out then fire it and re-check.
sometimes brass shrinks with the first firing,sometimes not.

A few years ago a gunwriter found out that he was getting better groups when using them right out of the box. I still check (and chamfer) them, specially for neck tension.
About the groups size, I cannot afford to know that kind of information....

I recently got my first .41 Mag and 1,000 cases. I found I pretty much had to size them in order to get consistent trim length.

Some .41 Special cases I got needed the works.

Ive found it's always good to full lenght resize new brass, no matter if it's revolver, pistol or rifle

I run every case through the sizer and then they get trimmed. I feel it gives a nice, squared off mouth for uniform crimping. When that's done I de-burr the flashhole. Some say I'm OCD, I say it looks good on paper down range.

Yes, for some reason I always resized them right oudda da box, for the little bit of extra effort it just makes me feel like all of the bases are covered!
