[QUOTE="Pdyson, post: 2792315, member: 74061"] On a warm day, I like to use aluminum foil taped to plywood for my 25 bore sight in and 100yd zero. I actually use an old roll of foil muffler repair tape I’ve had forever. Tilt it back so the foil reflects the cool sky temp. When the bullet strikes the plywood it will transfer heat which will be visible for a couple seconds so you can adjust. For 200yds or more I like to heat a steel target with a propane torch. That AR500 will glow bright for a long time. [/QUOTE]
