Hornady® Adds 300 WSM to Ammunition Lineup

Hornady is pleased to announce they are now shipping two different loads of 300 WSM ammunition. Both options offer exceptional accuracy and give hunters a dependable choice in either a 165 gr GMX or 200 gr ELD‐X bullet.

  1. Rumors of the deaths of the WSM and WSSM cartridge families are greatly exaggerated?
    Or Hornady is making legacy ammo for orphan Winchesters and Brownings?

    • Not all the cousins in that WSM/WSSM family have fared as well as the .300 and .325. Cool rounds though, I always liked the 270 WSM.

    • If you follow the “find out more” links you’ll go to the product pages where velocities, ballistic coefficients, etc are listed.

  2. I wonder if they are going to kill the 300 RCM. I really dig my 338 RCM, sweet round and package, not much else matches the whole package.

  3. Love my savage .300 WSM. It is my favorite small game rifle.
    Going to have to give some of that precision hunter stuff a try.

  4. These look like cool loads. The 165 GMX Full Boar averages about 3260 FPS from my 26″ stainless .300 Win Mag Win 70. I wonder if the. 300 WSM Superformance will be as fast. My buddy has a Tikka .300 WSM that he describes as a “turbo .308.”

  5. “Venerable”?

    The 1911 is venerable. The .375 H&H is venerable.

    I don’t think that word means what you think it means.

  6. I own two 325wsm rifles and love them. Ammo got expensive and is not on shelves any more. Hendershots and Double Tap make ammo. I may convert them to 300wsm if the trend continues. I’ll reload for now. WSM calibers have more energy at longer distances,and are flatter shooting in a light rifle. That matters when you take an elk, moose,eland,nyala,zebra etc. If you have to get out past 400 that comes in handy. It also matters on long hikes over many days in the mountains-and when hauling out meat. They are accurate too. I used to only have common calibers, but for the first time in my life I let myself get sold by the marketing and don’t regret it one bit. My Kimber SuperAmerica and Browning ABolt titanium are pretty neat setups. I love having added them to my collection.
