300 RCM
300 RCM is a compact beltless magnum for short actions. It aims to give 300 Winchester Magnum-like performance from a shorter case, with efficient powder use and strong hunting ballistics in handy mountain or timber rifles.
300 WSM
300 WSM is a short magnum 30 caliber. It offers near 300 Winchester Magnum performance in a short action, giving strong reach and power for elk and bigger game with snappy recoil in lighter hunting rifles.
300 Winchester Magnum
300 Winchester Magnum is the standard 30 caliber magnum. It gives a big step up in velocity and energy over 30-06, with enough reach and punch for elk and larger game at distance when the shooter can handle the recoil.
300 PRC
300 PRC is a modern long range 30 caliber built around heavy, high BC bullets. It is optimized for precision and consistent performance at extended distances, with enough case capacity to drive 200+ grain bullets hard and cleanly.
30 Nosler
30 Nosler is a beltless 30 caliber magnum with a lot of steam. It is aimed at hunters who want more than 300 Winchester Magnum without stepping all the way into the biggest overbore 30s, especially with modern long range bullets.
300 Norma Magnum
300 Norma Magnum is a high performance, long range magnum for very heavy 30 caliber bullets. It offers extreme downrange energy and trajectory, with serious recoil and barrel wear, mainly suited to dedicated long range and ELR rigs.
300 Weatherby Magnum
300 Weatherby Magnum is a classic overbore 30 caliber magnum. It drives bullets very fast for flat trajectories and hard hits on large game, but it comes with heavy recoil, loud muzzle blast, and faster throat erosion.
300 RUM
300 Remington Ultra Magnum is one of the hardest hitting commercial 30 calibers. It offers tremendous reach and energy for very large game but punishes the shooter and barrel, best kept for specialized hunting or long range roles.
