308 brass Overview
what is 308 brass
308 brass is a type of ammunition casing designed for the .308 Winchester cartridge, which is commonly used for hunting and target shooting. The brass casing is typically made of high-quality materials, such as brass or nickel-plated brass, to provide reliable performance and accuracy. It can also be easily reloaded, allowing shooters to customize their ammunition for specific needs. 308 brass is widely used by hunters, sport shooters, and military and law enforcement agencies for training purposes.
Lapua 308 brass begins with high-quality raw materials and superior smelting and metallurgical competence. Throughout the production process, the focus on quality control is consistent with Lapua’s exacting standards. Particular attention is paid to hardness, solidity and grain structure. All Lapua brass is tested to 30% overpressure according to Commission Internationale Permanente, the agency that oversees ammunition and component producers in Western Europe. This is not loaded ammunition.
308 brass preparation
With bulk 308 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.

testing 308 brass
Most new 308 brass can be loaded without sizing but you run the risk of uneven bullet seating pressure which will render the ammo inconsistent which may be important in a match. There are three ways to size cases. Match shooters use neck sizing as it is considered to produce the most accurate ammo and longest case life. For the most part, it isn’t an advantage and that brass frequently won’t chamber in other rifles. I have tried neck sizing but I found that after 3-4 firings the case has to be full length sized in order to chamber. Since I generally use full length as I hunt or experiment I don’t want to be bothered with ammo that won’t chamber. Full-length sizing is the most common method and is useful for most applications. Small base dies bring the brass back to original specs with the advantage that it should fit in any rifle tried.
For shooters with multiple rifles in the same caliber, this would be the way to go. In theory, it will reduce case life because it works the case more than the other two methods. In reality, I doubt that there is any real difference given the same loads.
308 brass from our indoor shooting ranges. This brass includes both military crimped primer brass and commercial non crimped primer pocket brass. Headstamps include but are not limited too Remington, Federal, Lake City, PMC, Winchester, and IMI. This brass is mechanically sorted three times then hand sorted before it ships to remove anything that might’ve gotten by. Every piece of this brass has been checked with pen light inside, one by one, to remove berdan primed cases(2 hole non reloadable brass). We spend a tremendous amount of time and labor sorting this material but customer satisfaction and repeat purchases tell us it is well worth it. As with all brass orders, we add an additional 2% to the overall weight and tumble clean the material at no additional charge. Purchase this brass with absolute confidence in quality, cleanliness, accuracy of sort, and price.
advantages of 308 brass
1. Reliability: 308 brass is known for its high-quality construction, which ensures reliable performance and accuracy. This makes it a popular choice among hunters and target shooters who require consistent results.
2. Reloadability: One of the biggest advantages of 308 brass is its ability to be easily reloaded. This allows shooters to customize their ammunition for specific needs, such as adjusting the bullet weight or powder charge for different shooting situations.
3. Versatility: The .308 Winchester cartridge is a versatile round that can be used for hunting a variety of game, as well as for target shooting and tactical applications. This makes 308 brass a popular choice among a wide range of shooters.
4. Availability: Due to its popularity, 308 brass is widely available from a variety of manufacturers, making it easy to find and purchase.
5. Cost-effective: While 308 brass may be slightly more expensive than some other types of ammunition, its reloadability makes it a cost-effective choice in the long run. Shooters can save money by reloading their own ammunition instead of purchasing new rounds each time they go to the range or out hunting.

evaluating 308 brass
One way to evaluate any brass is by feel. It may not be in scientific books but once you learn the technique feel that can be very useful ( see my article Reloading Ammo By Feel ). Every reloading operation requires some effort to achieve though most are relatively modest. If you are paying attention then you will notice the amount of effort needed to do that operation. If you are going along and one round is either noticeably easier or harder to do then there is a reason and you should see why. If you have consistent cases then everyone should have the same amount of feel. When you learn how to use feel the operations will be smoother.
Doing the normal reloading operations of the Kinetic Industries 308 WIN brass casings, I noticed that everything is consistent. That means that sizing effort is the same and the other operations show consistency. There is no way to measure that but if the loading operations are consistent from case to case chances are the ammo will be consistent also. In order for ammo to be accurate, each round has to do the same thing that all of the others do. That includes velocity consistency or a low standard deviation. Part but not all of that is the quality of the brass.
The standard length of the Kinetic Industries 308 WIN Brass Casings is 2.015 and the unfired brass measured 2.005 and was consistent. That was after sizing. After resizing, they measured from 2.001 to 2.021, in theory some would have to be trimmed to maintain length. In reality, trimming isn’t needed unless they were going into a match chamber. After another firing or two and trimming will be necessary. After the second firing, some of the cases stretched a bit so everything was trimmed to the recommended length. That is completely normal. Some of the loads were light which is an area that I like to experiment in. Cases that are too long can be difficult to chamber in addition ammo will not be consistent and can cause excess pressure in a few instances. That is especially true with small calibers and high-intensity loads. All of that is normal and I did nothing extra with these cases. I always chamfer the case mouth as it seems to make bullet seating more consistent.
ADDITIONAL INFORMATION ON THE 308 BRASS
There are many ways to make sure you have enough 308 brass for reloading. You can go to the range and crawl around the ground on all fours like that little creep from the Lord of the Rings movies, plucking up old cases whenever you find them. You can order bulk ammo and simply pocket whatever pops out of your chamber. You can even get accepted to the United States Army Sniper School, build up a respectable collection of empty brass, go AWOL, and then spend your life on the lam stopping only to reload once the authorities have lost your trail.
But the easiest way to ensure your brass supply is to order a package of 1,000 308 cases by Armscor. The Philippine manufacturer usually loads their new brass cases themself, but they also package them au naturel once they’ve been washed for the benefit of savvy handloaders such as yourself.
These cases are a better deal because Armscor did not give them primers – you thus have total control over so important an aspect of your handloads’ performance. Make sure you check out our .30 caliber bullet selection so long as you’re passing by.
