I actually have two questions, first if I buy the bags of brand new brass do I need to resize them before I prime and load etc?
Another quick question, is a Sierra Match King bullet a standard bullet or a VLD bullet? I was going to order a Redding micro seating stem and they have two types and asked that question. Thanks everyone Ross
 
You do not need to size new brass. Some people do though. If the neck is dented you should fix that by running it part way into the die.

Brass will usually be at the smallest size it will ever be when new. You shoot it and it gets a bit bigger, you resize it and it won't usually go all the way back to the same small specs as when it was new.
 
nope no need to resize new brass,

i run all mine threw a neck sizer tho just to make sure the necks are concentric, is it over kill for the less then obvious dented ones... probably, but for the 8-10 min it takes me to run 100 threw the press oh well

If it is "expensive" brass such as Nosler, Lapua! Hornady, etc.....no sizing needed.

If it is "cheaper" brass such as Remington or Winchester sold in the bags, run them thru the neck sizer, then chamfer and deburr.

+1. I neck size just to be sure everything is round and concentric. Depending on the state of the brass, I may trim as well before loading.

I will measure a few to find the shortest average length and always trim and chamfer them after neck sizing so that Im starting with somewhat consistent brass.
Not sure if the sierras are considered vld's or not
 
No real need to size new brass unless damaged

Berger vld's have a very long ogive which is why redding makes a seating stem specifically for them so if you intend to shoot vld's you will want that specific seating stem. Others seating stems will often touch the bullet tip instead of the ogive which can result in dented tips and bad seating. I would assume that redding should know what stem will be best for Sierra match king but if they can't I would probably go with the vld stem.
 
I run all new brass through a neck sizer (mostly for neck dents), trimmer (do it now, do it later...gotta do it sometime so might as well when you are playing iwht it anyway), deburr, and chamfer. Only way to be completely sure all are best possible for your needs.
 
Typically, brand new brass doesn't even touch the sides of a FL die, so the only thing that gets sized is the neck. I've run thousands of new cases through a FL die without lube for no reason other than round out the necks prior to chamferring.

That puts the neck size only, and the FL size guys doing the same thing and disagreeing about it. Its fun to watch.:D
