Scott Powers is currently in the NFA class and doing a project on Bullet Comparison/ Identifcation of 9mm bullets fired through various types of material.
Please let us know if you are interested. You will recieve no more than fourteen bullets to compare. I will be re-posting with more info.
Please email Scott at
