I've hunted with an 8mm Magnum for years. Excellent cartridge in my opinion. I generally use a 200 grain Speer with IMR 4831 and have never recovered a bullet from the elk, black bears or wild hogs shot with this load. Excellent penetration!! My chronograph shows that I'm getting 3,000 fps.
I've never tried the 220 Hornady but I did load some 150 Hornady bullets to about 3,400 and my brother shot a hog with this load. We never did find that bullet, all we know is that it didn't exit.
I know this doesn't answer your question but I wanted toot the 8mm Mag's horn a little.
