    Been shooting these since 2011 from an M40-A5 built by Tactical Rifles in Florida. They guarantee a .5 MOA out of the box, but mine is consistently less than .3. My brother, a trained and experienced sniper regularly wrings .25 out of the rifle with this round. David Rooney, owner of Tactical Rifles and one of the nicest guys in the custom gun biz, was insistent on this round from this company from the very first round to the current 3,000 +. The folks at HSM are great to deal with and their loads are scary consistent. I would recommend them to anybody looking for the best “store bought” accuracy in 300 WSM.

    Hoping that this .300 WSM match ammunition will be back in stock soon. I recently acquired a Browning Stainless A-bolt Stalker and had a Kahntrol clamp-on muzzle brake installed for bench shooting since I’m not a hunter.
    I’ve gone to Cabela’s, Bass Pro, Gander Mountain and various gun and ammo stores in the Raleigh, NC area and no one seems to have any .300 WSM ammo.
