Well, here a more unconventional way ....
My property has been partially logged recently and the loggers left quite some wood behind. So with my chainsaw I cut some woodplates and put them up as targets. The wood is softwood (pine or spruce) and I am shooting these with Judo points.
I have now a course of around 25 targets that I shoot from time to time. We even had a little stump shoot a couple of weeks ago.
Cost? I used 6 nails (6 - 8 inches) per target, that's it ....
Now you will probably ask aren't the arrows going to break?
I am shooting a 55 pound longbow with wood arrows and a friend of mine shoots a 70 pound Howard Hill longbow also with wood arrows. None of our arrows broke because of hitting the target.
However, you really have to use Judos as a point. They will stick but not penetrate ... and can be remove easily. I have tried field points once and of course broke my arrows when I tried to pull them out ... ;-(
I am wondering if somebody has done something similar? I have never seen this sort of setup before .... The idea came to me while small game hunting up north ... and when I took practice shots with my Judo and I realized that the Judo sticks nicely in softwood ....
