I've used the .30 caliber 200 grain for a few years out of my 300 H&H. Velocity is roughly 2950-3000 fps (26" barrel). For African game, I took 4 animals with that bullet - Southern Greater Kudu, common Sable, common Nyala and common Waterbuck.

The Kudu was about 100 yards shot through the neck, bullet exited.

The sable was about 120 yards running, slightly quartering away from me. Hit it about mid-ribcage and it exited through the offside shoulder.

The Nyala was shot as it spun to leave at about 70 yards. The shot went in just above the tail and exited the chest. Second shot was in the neck as the bull struggled to rise. It also exited.

The waterbuck first shot hit a limb about 10 feet from the muzzle (I did not see the limb) and hit the bull a little far back. Second shot was headon in the chest, the bullet exited out the ham. Put a final shot into it as it tried to slip away from about 10 yards through the shoulder blade and exited the chest (shot from above).

The North Fork bullets are the most accurate I've tried in this rifle. Based on the performance in the size of animals I took, I'm sold. I didn't recover any of the bullets from animals that are the size of what the 300 H&H is designed for. I can't say if they are better than the Swift A-Frame, but they are more accurate in my rifle. The A-Frames I've used in the past seemed to duplicate the Nosler Partition performance, with maybe a little better weight retention. All three of these are outstanding bullets.
