Match Grade Brass Preparation (By Tom at www.BigSkyAmmunition.com) 

For years people have always battled over how to prep there long range brass.  It seems everyone everyone has a different method of prepping their brass, but is there a true right or wrong?  I can’t say yes or no to that, as long as its working for them.  Here at BigSky Ammunition though, when we have a customer contact us for either a custom prepared brass or a precision ammunition order for their rifle or for a rifle we built for them, it all starts in the brass preparation.  Brass preparation is always the foundation for precision rifle ammo.

Brass Preparation starts with a quality piece of brass, Lake City, Federal, Winchester, Remington.  All of these headstamps generally are good brass.  First, make sure you have cleaned your brass very well.  This starts a completely different dispute all together, but your brass should be cleaned before they ever touch the sizing dies.  

Dies are another big debate.  Standard or bench rest/competition dies.  In simple terms a good set of Redding dies will generally do everything that needs to be done.  If you are going out for 1000 yard bench rest competitions, and are trying to achieve the tightest groups possible then you might consider a set of custom cut dies to match the chamber of the rifle.  

Once you have the brass ready for sizing it would be wise to do a very close inspection of the quality and condition of your brass.  Carefully inspect them for any damage to the shoulder or head area.  One area that is commonly overlooked is inside the case, right above the flash cup.  This is generally where you see most of the case head separations.  One easy way to check for this is to take a paper clip and straighten it out for the length of your case an put a sharp 90* bend at the very end of the tip.   This will let you run it across the inside of the case to see if you have a lip or fissure inside.  If you find a lip discard that brass an go to the next.

Once you have found your brass that will be used you can start with your sizing process.  A good lube is a must.  A good thin lube is the best.  Lube liberally.  

A lot of people use also use a bushing style neck sizer set up and again there are so many options out there that it often comes down to what you feel confident in and how far you want to take it.  If and when a custom chamber is being sized for you will need to know the neck dimensions,  along with length, but with an off the shelf target or tactical style rifle a standard set of Redding or RCBS dies will be just fine.  

You can control the neck tension with different size expander balls, you want a firm tension on the bullet, but not so much that you will have to force it into the mouth.  

Where a lot of accuracy is lost is in trimming.  When trimming your case its very important to make sure each case is trimmed the same, when you have a 1 or 2 thousands difference you end up changing the neck tension by the length of neck area that your bullet is seated into.  Once you have gotten your trimmer set so you are getting the precise length every time you can head to the internal flash hole cleaning and forming.  It does not matter what tool you use here as long as it is doing the job, people will either look over this, or over think it.  This will really affect how your primer flash enters the case.  An odd shape flash hole  will cause a uneven start on your powder.  Just make sure that every primer cup and flash hole is clean and uniform.  

After this your once step closer to loading.
