Good advice and guessing or hoping you might have at least a 6" barrel. If so, you may be tempted to use a tree as a rest. Keep in mind that you will get a bit of fire, from your cylinder gap. Even with a pair of gloves, you will get a good burn. Let's just say that there are things that I have learned, the hard way..Don't take any shot you wouldn't take with a bow and you will be fine.
This Saturday, I'll be going on my first...
...am looking for any advice...
Practice,practice,practice...
