I went back and checked, nothing was said about weather it was kosher to shoot a little first or if we were supposed to shoot cold so I dont think it was cheating to have taken some practice rounds at a different target first.

It has been almost 3 months since I last shot, had to work the cob webs out, and during hunting season I never go more than a week or 10 days without shooting so I figure that puts me on form with how I would hunt.
