For small game a judo point works well. I have even used field tip with a fender washer behind it for shocking power. A fender washer is a standard washer with a small hole in the middle you should be able to find one that will have a hole just big enough to fit between the shaft and the field or target tip. you are adding grains so for a 125 grain head I would use a 100 grain field tip for a 100 I would use a 85 grain tip. You can get the washers at any hardware store. For Turkeys I would use your normal broadhead and you can get grabbers that fit behind the broadhead to keep the arrow into the bird. Groundhogs I would use the same set up as for turkeys. If your shooting critters that are tough use a broadhead set up with a grabber if need be. Fox and Yotes use a broadhead.
