I just got back from a hog hunt with my 454 casull and used 300 grain Swift A-frames. It hit that ~450lb hog like a hammer! In the video it almost looks like the pig gets lifted off it's feet when it gets hit. I also recovered the bullet which expanded perfectly and it had 90% weight retention. I would recommend them over XTP's all day long. My Ruger Super Redhawk was also wearing a Leupold Deltapoint Pro which I have on multiple pistols and carbines. Great optic.
