HSM loads the Sierra GameChanger bullet to 2870 fps in this .30-06 Springfield offering, producing 3018 ft-lbs of muzzle energy. That velocity sits right between the slower Sellier & Bellot eXergy at 2785 fps and the faster Sig Elite Hunter at 2950 fps. The 165-grain weight hits an effective middle ground for the caliber. Heavy enough for elk-sized game, light enough to keep recoil manageable through a full day of shooting. The 0.53 G1 ballistic coefficient means this bullet sheds velocity slowly downrange, holding energy better than most 165-grain competitors.

The GameChanger bullet separates this load from standard hunting options. Sierra designed the projectile with a translucent polymer tip that initiates expansion on contact, paired with a jacket profile that controls how far the mushroom opens. The result is a bullet that opens wide at close range without fragmenting, yet still expands reliably when velocity drops below 1800 fps at longer distances. That two-stage behavior matters when your shot might come at 80 yards in timber or 350 yards across a canyon. You get the same terminal result either way.

This load fits western big game hunting better than most alternatives. The combination of 3018 ft-lbs of energy and controlled expansion gives you the penetration depth needed for quartering shots on elk, where the bullet must travel through heavy muscle and bone to reach vitals. It also works well for mule deer at extended range, where the high BC keeps the bullet supersonic and accurate past 400 yards. Hunters who split their season between deer and elk will appreciate having one load that handles both without compromise.
