Norma 300 WSM Brass Available In Stock

Norma 300 WSM Brass: Norma Shooter’s Pack brass is packaged by Norma in convenient quantities. The Norma USA Brass is world renowned as being the absolute highest quality brass available. These cases start off with the best possible raw materials with the narrowest tolerances.

The case necks are annealed to soften the brass and prevent gas leaks the case body is at the optimum hardness to avoid any unnecessary stretching. New, unprimed brass that features chamfered and deburred case mouths and a punched flash hole (magnum calibers are drilled). These cases should be sized before loading. This is not loaded ammunition.

Brass Preparation: With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder.  These imperfections occur in the final tumbling wash operation after the case mouth has been annealed.  Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur.

Minor dents are normally removed in the first firing and will not affect case life or performance.  On non-plated brass, you may also notice all the anneal stain might not be polished off, which may give the case neck a pinkish color.  With some smaller caliber cases you may notice the case mouths to be slightly belled.

With all new rifle brass, you should first straighten out the case and case mouth, then chamfer and debur the case mouth inside and out.  To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass.  To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth.

Truly, choosing between the 300 Winchester magnums comes down to the length and also weight of rifle you prefer. If you like short, quick actions, go with the WSM. If the 30-06-length standard action works for you, stick with the old 300 Win.

  • Is brass the best ammo
The Truth About Brass vs. Steel Ammo - Pew Pew Tactical

Brass ammo is generally considered to be better than steel-cased ammo because it creates a better chamber seal than steel. Thus you have less blowback into the chamber and the receiver. Brass is better at this sealing action because it is more malleable than steel. So, it expands to snugly fit the walls of the chamber.
