stopped a maruading cottontail in the garden with 240 lee tl in a cowboy+ load.. this load shoots great to 50 yds. easily golf ball or minute of squirrel head performance. mr bunny took two thru shoulders, first at 20 yds, ran 50 more and was stopped by second shot. I know...head shots will be effective. wanted to see how this would do. really not any better than a 22lr. what can I do to smack them harder? love this rifle and it has become my anytime fun gun.
