I am using a Handi Rifle in 223 bull barrel. I have load that I believe is perfect for my rifle. It shoots great. I am using 50gr Sierra Blitz Bullets and they are extremely fur friendly on the yotes. They are proving to not be so good on the coon however. Oh well, I am getting a 17HMR or a 22Mag for coon next year anyways.
For the doubles, on one of them, we called both in at the same time and we each shot one, and the other time, we called one in, shot it, and kept calling. the other one came trotting out in the field about 2 minutes after the first one was shot. ALWAYS keep calling!!!
