Science Fair anyone?

My older son is getting set up to do a science fair project and he wants to do it on terminal ballistics. His current plan is to use his 54 Bobcat and PRB shot into damp clay. Due to the teacher mentioning something about developing as much data as possible but limiting it in terms of variables he is planning on using one powder level and just the PRB and doing 10 shots each at 15 yard intervals from 15 yards to 150 yards (100 shots total) and measuring the muzzle velocity (for ref.), depth of penetration and mushroom diameter.

I had thought about using a product from Midway (see it at this link http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=739849&t=11082005 ) but it would take forever to do the testing with only one and it would cost a fortune to buy a bunch of them so I guess the damp clay will have to do. I would also like to include more than one powder level and multiple bullets but this is his project and time is limited.

Like I said, he is still getting things together and working on his test plans so I thought I would post on here and see if anyone had suggestions on his plan or other ideas to test instead of what he is proposing?

Thanks in advance for any input.
