Hi everyone. ive recently bought myself a pre owned AA TX200 MK2. ive read quite a bit of stuff on here about the recommended killing range for rabbits, 35 / 40 yards, required group sizes etc. i don't have a chronograph so im wondering if there's a common house hold item i.e a tin of beans etc that i might shoot to measure at what range "my" rifle would kill a rabbit. eg would it need to shoot straight through the full tin, or would penetrating just one side represent enough power for a clean humane kill, any idea's =) ?
