First Question:

I practice on a target similar to this:

Can I shoot this thing with a broadhead? Will I be able to get it out? The target seems to be filled with sheets of cardboard wrapped in a plastic bag with some cotton stuffing in between the sheets. I am don't want to have a broadhead lodged in my target messing up my arrows from now on.


Second question:

I am thinking about changing broadheads. Right now I am shooting Cabela's brand fixed broadheads with replaceable blades, and the blades don't seem like they are held securely enough for my tastes. I am thinking about moving to a one-piece fixed broadhead such as this:

Is there anyway I can ensure that the arrow flies very similar to my field points? I have read that you can tune your bow to do this, but I am not that good at tuning it.
