300 wsm brass
The 300 wsm brass is used in .300 Winchester Short Magnum is a 7.62mm short action magnum cartridge with considerable effect. It is very similiar to the regular .300 Winchester Magnum in terms of ballistics, but takes advantage of the short action design which allows more powder to sit closer to the flash hole. When the primer ignites, it allows a more uniform burn which in turn translates into more efficient use of energy. A 300 WSM can therefore achieve the same ballistics with less powder.
300 wsm brass Overview
Hornady produces 300 wsm brass with the same precision, attention to detail and focus on perfection that has made them a world leader in bullets. They measure their brass for consistent wall concentricity, tests pressure calibration to ensure uniform case expansion and hand-inspects each piece.
This dedication to quality ensures proper seating of the bullet both in the case and in the chamber and consistent charges and pressures. The result is optimal velocity and repeatable accuracy from your cartridges. New, unprimed brass. This is not loaded ammunition.
preparation of 300 wsm brass
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.

had less throwaways then with winchester brass which was what I had been using. neck size new brass, some winchester would not feed. Pull the bullet, dump the powder, pull the decaping pin, full length resize to get winchester to work. Just neck size Hornady. Winchester quality control cost them a customer.

So far so good this the second time I’ve purchased these cases. They reload as expected, minimal case damage from factory bulk lots. Shipping from the USPS could have been better box was mashed.

The Hornady brass worked well. The only problem was the case mouth was rough and I had to use a reamer to smooth it. The Hornady brass is much better than the Winchester of the same caliber.

Availability is the biggest issue here. Being able to locate a supplier of 300 WSM brass has been difficult lately. It appears to be back ordered everywhere else I have attempted to purchased this product.

I have reloaded this brass three times and am very impressed. It weight sorted very well with over 80% being within 1.5 grains and only a couple of real outliers (2.5 grain extreme spread on weight). Up until now I have only used the plated Winchester stuff for my .300 WSM and I had terrible luck out of it. This brass is much easier to work with and a lot more consistent.
