Thread: New Brass - do you full length size it?

Hi Guys

Just looking for a little advice on this one. I haven't loaded brand new brass before - have always bought loaded ammo then reloaded. But I have a plastic bag of 100 brand new Norma 6.5 x 55 brass and I'm wondering if it's a good idea to full length resize it to iron out any lumps and bumps it might have got along the way,*or if it's good to just load it up and go.

thanks very much in advance
Will

I only full length size new brass if the case mouth has obvious dents. Most Norma stuff I've had hasn't needed sizing.

Hey Will, id full length and trim it mate. Then you know they are all uniform n dimension to start with

Thanks mate, appreciate it. I mean thanks both of you Guess I'll toss a coin.

I do
Start everything as uniform as possible

I don't. Just check headspace and trim length then load it.

Load it, use it, reload it.

Done it that way for damn near 30yrs, never had a problem.

How much does your trim length vary/alter after firing ?

I only trim brass thats had at least one firing

My Rookie thoughts after asking similar question a while back would be to just check length and batch together any that have slight variance. Load and fire to form to chamber then trim/neck size next reload.

Well .223 brass adi and lapua, the headspace and trim lengths are pretty much bang on for book spec and my chamber. I just check to know the brass will chamber and trim length check for safety. So far it's always good. I just load it. Never had to trim new brass.
I'm not sure how much it grows, no more than normal.
I trim every load anyway to have the cases all a constant length, not trimming to book spec though.
I don't know if this is right or wrong. But I don't see the point in sizing it if there already the size I want. They shoot as good as any other load.

have never bothered with sizing new brass, but had one batch of Norma brass for my 7mmRM where primer pockets were tight as the nuns you know what. Had to spend a bit of time uniform pockets to get primers seated correctly.

Thats normal with some batches of Norma brass these days

Just lube the primer pocket with redding sizing lube on a cotton ear bud and the primers are far easier to seat to full depth.

Do not bully/force them in, that mindset should be avoided with anything to do with reloading, gently gently protects your face, and eyes, and ears, and fingers..............

Jeez mate, thats pretty gruesome.
Hand priming or press?

what the F*** happened?

I inspect and weigh my new brass looking for odd balls, throw them out. Then I neck size and put the case through my Lee Ezi-trim to make sure the brass is reasonably consistent then fire form it. I neck size from then on and use a Wilsons chamber gauge as a post reload check, final weigh to make sure I have not made a squib and box it ready to go. This would be the basic stuff covered.
