300 WSM Ammo

300 Winchester Short Magnum (WSM) ammo was introduced in 2001 and would become the first cartridge in Winchester’s short magnum line of bottlenecked centerfire rounds. The 300 WSM is similar to it’s older brother the 300 Winchester magnum, but can be chambered in a short action rifle that is often a much lighter rifle.

The weight of the 300 WSM is a distinct advantage when hunting in the high mountains or across the Texas hill country. A lighter rifle is a blessing over rough territory, but big game needs a big round so the 300 WSM is an excellent compromise. The 300 Winchester short mag can be an absolutely devastating round to medium and large game commonly hunted in North America.

The round is very powerful and very capable. The caliber fills the role of a guide gun quite well, its power can be counted on for defense against animals, or as a humane secondary shot should the primary bullet only wound your target. Take a look at our in-stock 300 WSM ammo for sale below:

    This is the only kind of ammunition that I have found that more consistent to shoot in my rifle is a tighter group and it's what I use hunting.

    150 grain, I have taken several white tail deer. I did use the 180 grain for for 9 of my mule bucks,& 2 does past years. I also used 150 grain on monkey, 3 Baboons, 2 Blesboks, 2 Impala 2 warthogs. I used 180 grain on 1 Gemsbok, 1 Wildebeest, used 200 grain on Waterbuck, 1 Sable 2 Kudus on several Safaris in Africa, I wish Winchester would make more ammo for the 300 WSM very disappointing when trying to find ammo

    This is my go to ammo. No matter what gun or caliber I buy this is the ammo I buy first. I have tried to buy other brands with no success.

    I shot 3 wild boars from 200 yards, 100 yards and 50 yards and none of them took a step after being hit by these bullets. I also shot a big whitetail buck quartering away through the lungs and it only took about 3 jumps and piled up. This ammo puts the game down quickly!
