300 Win Mag Brass Available In Stock

300 Win Mag Brass: Lapua World-class 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.

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.


FAQ On 300 Win Mag Brass

  • What is the trim length for 300 Win Mag brass?

300 WM case has a trim length of anywhere from 2.600″ to 2.620″. Most trim lengths target the dead middle of that range to allow for tolerance errors and trimmer user alignment errors. With an adjustable manual trimmer, I usually try to aim at more like -0.015″ from the maximum number.

  • What is the advantage of a 300 Win Mag?

300 Win Mag is capable of shooting accurately at long ranges. It has a flat trajectory and can maintain its velocity at distances of up to 1,000 yards, making it an ideal choice for long-range hunting or shooting competitions.

  • Do you need to trim brass before reloading?

In the standard calibres we have to trim because, as the case gets longer with the brass flowing forwards, the case will end up too long to actually chamber in the rifle. So, we trim the case back to a set distance to give us clearance in the chamber.

  • What is the killing range of a 300 Win Mag?
300 Winchester Magnum - Wikipedia

The . 300 Win Mag sees use in long-range benchrest shooting competitions and has been adopted by law enforcement marksmen and by a few specific branches of the U.S. Military for use by snipers. Maximum effective range is generally accepted to be 1,210 yards (1,110 m) with ammunition incorporating low-drag projectiles.

  • Should I save my ammo brass?

You can reload your brass and get more practice out of the already used rounds. If you want to make a little extra money, you can recycle your brass bullets and get up to $1.50 for every pound. That may not seem like much, but hundreds of rounds can add up fast, especially if you love to shoot.

FAQ On Winchester Magnum

  • How powerful is .458 Winchester Magnum?
458 Winchester Magnum - Wikipedia

Winchester achieved and surpassed this performance with their . 458 Magnum cartridge. Current performance standards for the cartridge allow it to launch a 500 gr (32 g) bullet at a velocity of about 2,150 ft/s (660 m/s) through a 24 in (610 mm) barrel.

  • Which is more powerful 308 or 300 Win Mag?
300 Win Mag VS 308 - Wideners Shooting, Hunting & Gun Blog

The 308 can push a 180gr soft-point at a velocity of 2,600 FPS (at the muzzle). With that said, the 300 Win Mag can propel the same bullet at 2,960 FPS – that’s a faster speed with more energy behind it. The 308 bullet has a drop of 9.1″ at 300 yards and a drop of 51.9″ at 500 yards.

  • Is 300 Winchester Magnum too much for deer?

No, though it is far more power than necessary. A good 308 round will kill a deer very quickly and humanely within 500 yards. It will go in one side, tear up the appropriate organs and exit the other side. The 300 WM will also kill that same deer just as dead, but will also cause a lot more damage to meat.

FAQ On Brass Casing

Brass-cased cartridges are the most popular type of ammunition on the market today due to durability, corrosion resistance and ease of reloading. Introduced in 1846 by French gunsmith Benjamin Houllier, the first brass-cased cartridge. Used a pinfire ignition system that was quickly improved upon.

  • Is brass casing good?

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.

  • Why is brass used for casing?

The most popular material used to make cartridge cases is brass due to its good corrosion resistance. The head of a brass case can be work-hardened to withstand the high pressures, and also allow for manipulation via extraction and ejection without rupturing.
