Last year I was given a hand me down Handi in .223, but ive just now gotten around to fooling with it. Before finding this forum, I started out by trying some 55gr winchester white box with no luck. Next I found some 45gr remington hollow points. The results were even worse. After looking around for some answers I found this site. Since then, I've loaded up some 45 grain sierra varminters with 22 grains of IMR 4198, and things are looking promising. I imagine I'll know more once I get a chance to shoot this thing from a bench rest. After years of hunting coyotes with an AR, I didnt think an old single shot would be quite so much fun to shoot.
