A long post but bear with me,
I'm currently studying my Bsc in Forensic science at uni, got chatting to a lecturer who was annoyed at how hard it was to do any ballistics work with students. So i suggested approaching my club and asking to do a guest day that i would RCO to give students a chance to do some live firing, ( at the moment you can do your masters project on legality of air weapons by sticking 50 shots of different pellets through a chrono in a lecturers garden and writing it up properly). This has all been given the green light and will be used as proof of concept for the uni to build a range, because that is all the proof you need to spend a few thousand when you charge each student 9,000 a year!!! (rant over).
The thing the lecturer is most interested in being able to do is capture an intact projectiles (EDIT: a .22LR) to compare barrel markings (such as you would to match or eliminate a firearm to a crime) does anyone have any suggestions on the best way to do this on and indoor gallery range with a steel backstop? I'm apprehensive of using a water butt because i have never done it or seen anyone do it and a misplaced shot will flood the range?
Cardboard box full of sand?
Gel? (a pricey option)
There are still lots of possibilities and variables the only thing set in stone is that it will have to be on a 30m indoor gallery range.
Thanks for your time and any response will be highly apreciated.
