Suggest two cat eye tacks set at 50 and 100 yards. Shoot at the tacks with a red lens and small caliber rifle. Closets to eye (tack) wins. Maybe $5.00 per chance with 70 percent going to winner. Idea. I can provide Cz 223 caliber rife with light force light on it and 4.5x14 scope. Will be shooting Stoney point rapid pod shooting sticks or buckwheats outstanding shooting rest. This would be a very interesting and fun shoot..
