Oh you're gonna like that, its a lot of fun. I bought one last year and Ive shot a hog and a nice buck with it.

The bag target is the way to go for sure. You'll just have to figure out something else to shoot broadheads at and make sure they fly like the field points. Some of them will plane at those speeds. You will want your arrow to be front heavy. That will help them fly right. Do some research on arrow F.O.C. you will probably want around 20% more weight on the front half of your arrow. That will give you extreme accuracy and make a solid fixed broadhead fly right.
