Looking for some input from all you guys that do lots of shooting and pattering. My son wants to do a project for school on shotgun shells. He want to do a test on three name brand manufacturer of shells and he wants to do a force = penetration on three different types of shot like copper, steel and tungsten from each manufacture of shells. He wants do show witch shot will penetrate more. I was thinking like using 20 gauge 2 3/4 # 2 or buckshot to do it with thinking it be easier to measure with less shot to weed through. I was thinking of plywood for backing but that's lot of plywood to waist , not sure but I was thinking it will take at least three layers of 3/4 at 2x2 each, and looking at doing at least three shots of each manufacturer to get a percentage. What have all you used for backing and do you thing cardboard would work or any others? Not sure what to expect on the penetration but sounds like some fun at the range shooting. Any help will be appreciated Thanks.
For penetration I'd use wet newspaper, or a cardboard box layered out with sand in between each layer. Never tried to measure penetration with a shotgun.
Phone books work well.

On youtube there are numerous videos on how to make ballistics gel, which would show after impact what the pellets to as well... Also, all the materials can be bought at your local grocery store.... Hope this helps, good luck ;D
Be very carefull what your son takes to school, this zero tolerance has made big trouble for very minor things. good luck to your son i hope he enjoys his experment and gets a good grade.
