I recently picked up an Air King 54 in .22. I absolutely love these sidelever springers. I have one in .177 and I always said it was my favorite air rifle to shoot until I got this one. It's equally accurate but definitely has more "thump" when it's hitting steel. I am getting around 798 fps with Crosman 14.3 gr pellets. I am definitely a Diana fan. Theses guns are heavy for some people but I love the accuracy.
