What is the largest animal you should use judo points on? The largest animal i was thinking about using them with was groundhogs. My father-in-law has a small business that is just barely in the city limits and last summer i used my .22 to take a couple out( all shots were safe, i was shooting into a huge hill behind the business). I don't want to use it again because of the fact that it is in the city limits, so i was hoping to use judo points. Also how accurate are they? what is there effective range? i'm thinking about trying squirrel hunting with my bow to make it a little more challenging.
