Do you resize virgin brass?

[SloppyJ]

I resize virgin brass for sure. That is the only time I will leave the sizing button in my bushing die to center up the neck. Chamfer it and deburr, then load. Typically the lengths are very close to the same but if there is a big variance, I'll trim them all to equal the shortest piece.

The powder charge will change after it's been fired. Typically it will take less powder to achieve the same velocity when compared with new brass on it's 1st firing. My thought it that there is less brass movement when fired and that more energy can be utilized on pushing the bullet.

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.
