300 rum brass Overview
Nosler 300 rum Brass was developed to complement their line of custom bullets.
Each lot is weight-sorted to provide consistent measurements and capacities for accurate loads and features a Nosler head-stamp.
Before shipment, Nosler chamfers and deburrs the case mouths and deburrs the flash hole.
Fully prepped and ready to load upon receipt, each piece of brass offers consistency in trimmed length and neck wall thickness.
This brass is new and unprimed. This is not loaded ammunition.
The 300 rum brass is a 7.62mm high-capacity beltless cartridge suitable for both large game hunting and long range endeavours.
The beltless construction was thought to allow more a accurate chambering as well as increase the life-span of the case.
That particular construction has however been shown to have minimal bearing on such parameters
. It is one of the most powerfull 30-caliber cartridges available,
with magnificent velocities and hence reduced bullet drop, designed to handle the largest game on the North American continent.

300 rum brass Specifications

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.
