How do I get a gold metal for level 18, the black cliffs. The best I seem..

It took me a long time but basically you have to have the last shotgun you can earn and just be in the zone, or use the force or something like that. You have to hit all of the jackalope's, use your wiley x vision at the right times and don't miss. One of the key parts to getting past this level with a gold is the part where the grouse are hopping out of the bushes from left to right. You can shoot the bushes and hit them for about 2 seconds before they hop in the air. I did this level repeatedly (for about a month) and somehow got the gold, not sure I could do it again. This is a hard medal to earn but not as hard as getting 100% accuracy shooting the fish which is the last goal that I have to achieve to complete this game and open up the wilderness, going on 3 months of trying now, getting annoying.
