450 Bushmaster – 260 gr FMJ – Remington UMC (L450BM1 / 23661) – 200 Rounds

Big bore practice ammo is hard to find, and shooting premium hunting loads every range trip gets expensive. This listing is Remington UMC 450 Bushmaster 260 grain full metal jacket ammo, MPN L450BM1 (Remington item 23661), sold as a 200 round bulk case for affordable 450 Bushmaster training.

The 260 grain FMJ bullet is a non-expanding target bullet, which makes it ideal for zeroing, function testing, and getting comfortable with the 450 Bushmaster’s recoil before hunting season. Remington lists this load at 2,040 fps with 2,402 ft-lbs of muzzle energy, so it gives you realistic recoil and point of impact practice at a lower cost per round than hunting ammunition.

The 450 Bushmaster was designed for the AR-15 platform and fits a standard AR-15 lower with a 450 Bushmaster upper, bolt, and magazines. It is also chambered in bolt action rifles such as the Ruger American Ranch, which makes it a popular choice for hunters who want one big bore round for both platforms. A common question is whether 450 Bushmaster is legal in straight-wall cartridge states such as Michigan, Ohio, and Indiana. It is a straight-wall case and qualifies in many of those areas, but regulations change and differ by state, so always confirm your local rules before the season. Compared with the 350 Legend, the 450 Bushmaster fires a much heavier .452 inch bullet, which gives it more energy and a wider wound channel at the cost of more recoil, so it suits hunters who value stopping power inside about 200 yards. Because FMJ bullets do not expand, this is a range load rather than a hunting round. The 200 round case keeps you shooting all year.

Remington UMC L450BM1 is new production ammunition, not reloads, made in the USA. Each cartridge uses a brass case with a boxer primer and is non-corrosive, and the boxer primed brass is reloadable for handloaders. Buying by the case also keeps you on one production lot, so point of impact and velocity stay consistent from box to box. This case comes in factory packaging as 10 boxes of 20 rounds for a total of 200 rounds of 450 Bushmaster 260 grain Full Metal Jacket (FMJ).
