Best thing to shoot a broad head to practice?

you really dont need to shoot with your broadheads to practice unless you buy broadheads that are specifically for practice, because as long as a field tip is the same grain at your broadheads it will shoot the same. i would not recommend shooting your good broadheads because it dulls your blades, but if you do you should shoot the cube targets made of layered foam and as long as you pull the arrow out as straight as you can it doesnt rip out the foam-----------------This isn't so true. I have bowhunted for many years and i find it best to always shoot what your going to hunt with, that way it shoots true just the way it will in the wild. You can always sharpen the blades if they get dull. I have seen arrows fly different with the same grainage in a field point, in my opinion use what your going to use in the woods
