Do you resize virgin brass?

[DonE911]

Lots of people take new brass and load it... maybe round the necks if dented.

I do full prep on all new brass... which is Lapua, Alpha, Pederson in Rifle calibers. I did get a good deal on 500 pieces of Nosler premium in 6.5cm so I use those, but normally would not. ( except AR rounds )

.FL size, turn necks to 85 percent, chamfer blah blah.... wet tumble and dry. On good brass the work to prep it is minimal and a part of the hobby i enjoy. I know that many people would rather go square dancing than turn necks on brass.... lol

On fired rifle brass I knock out the primers with a universal de priming die and wet tumble before the brass goes thru my sizing dies. After resizing they get wet tumbled again. I personally want clean brass at every step.

The exception is on handgun or high volume 223 brass... those get FL sized, wet tumble, dry and load. Trim if needed on the 223 brass.

I run a mandrel through to straighten necks and tumble in dirty media to get consistent seating pressure.

If there is significant bur or lack of a chamfer I do that. Lately with lapua brass i haven't bothered doing either as there is already a little chamfer and no bur.

I run it through a FL sizer with bushing and then run a mandrel for consistent neck tension. Trim following the next sizing prior to second load.

Might be excessive, but for consistency sake, I always size new brass.

I've had no issues that way, but thats not to say you have to at all

Fairly new reloader here. (1 year)

All of my reloading so far has been on factory brass fired from my rifles. (300 rounds)

I only full length size with Hornady dies and only bump the shoulder 2-3 thou.

I recently finally purchased some new brass.

My question is should you resize virgin brass? I have inspected all and none have any dents or bent necks. I just planed on chamfer and debur and load. Don’t want to work the brass more than I have too.

Thanks for the help.

If using a quality brass such as ADG, my process for virgin brass is mandrel, chamfer/deburr and then go ahead and load.

I’m certainly the minority on this but 9 times out of 10 I just load it weather it be Hornady, Starline, Peterson, ADG, or LC. Occasionally will chamfer if needed and I have the time. Almost never run through a die or mandrel unless the necks are really beat up. Use case can play a big part in prep. The majority of the time I’m shooting 600 yards and in at steel so likely not noticing a difference between just loading or taking the extra time on initial brass prep.

As long as its good quality brass I only hit it with a mandrel and chamfer/deburr.

 

[TexasAg99]

I prefer all my loadings to have as close to the same neck interference as possible. So I size all brass, new or already fired that way I know what I am getting. Is it overkill. Maybe, maybe not, but I like to know what I am working with.

I decided to not resize this 10 shot group of Hornady new brass to see how it shot. I only Chamferd/deburr the cases that appeared to have uniform necks. Loaded 10 with Staball 6.5 and was happy with the results.

This $200 Thompson center compass utility shoots well.

Thanks for all the input!

Looks good. Imagine how much better you'd feel if you dropped that group to 0.99 MOA by using a mandrel first for more uniform tension!

I deburr/chamfer, then mandrel to tension. Probably can't measure the difference, but I don't like the feeling I get when I seat a bullet that's significantly harder to seat than the one before.

I lube necks with carbon powder, mandrel, chamfer, debut, and load. The mandrel restores concentricity in dinged necks before the final steps, so its worth it to me even if It has little effect on the group (assuming no neck dings)

 

[RME]

One extra time through the resizing die is not really going to be noticeable in the usable life of a brass case.

I don’t think so either. Years ago I tried to run some different cases through an FL die to see how long it would take to split a neck or something. I forgot how may times it was now but I eventually stopped after 100 or 150 times and nothing happened.

 

[huntfishhike]

I have alway full length sized my shiny new brass, seems it at least helps to true up the neck if nothing else.

Mandrel,chamfer, deburr
