CG, there is something to the oil in the hollow pt cavity. Wait until you shoot them at long range! I shot a bull elk at 400ish yards and watched the bullet “seek” it’s way to the elk through the scope! It looked like a TOW missile on its way to the target. It seemed much more visible than a bullets shockwave. It’s was actually kind of a distraction for me as I’ve never experienced this with any other bullet. Certainly don’t care for it. Hammer spokesman mentioned the oil thingy. Dunno, I didn’t see it when shooting long range at steel but I certainly did with the elk.
