well while messing around today my son and I came across a rabbit.it was either 45 ACP or 270 Winchester short mag. I chose 45 ACP. I aimed at the head and one shot one kill end of story. my son is pretty excited because now he gets to try rabbit. I was also pleased to see a nice cubby of quail today. I also showed my son what they look like. There were at least 15 to 20 quail in the fence line.
