Do you resize virgin brass?

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.
