I live in the woods and so I spend most of every day outside. I have everything from wild boar to deer, rabbit, squirrel and so forth. These are to large for small game and just not practical for use in a low poundage bow.
I use these in my crossbow and they work great on hogs and deer. Keeping in mind that the weakest point is where they thread into the arrow shaft.
If you just want to thin out the groundhog population, have fun, leave them where you shoot them and do it cheaply.
