[sdiy] sort of OT: bullet ricochet noise?

[anthony]

I think we're both on the same page when we say "inducing spin" we mean a 
different spin from the original torsional spin induced by the rifling. So I 
guess it would be be more accurate to say the impact induces a "roll" or a 
"new spin" or "flop" since the rifling makes it spin along it's axis it's a 
symetrical spin, but then richocheting makes it do an oblong radial flop 
which would make more noise than it's axial spin.

I wonder if I could do something like that on my MKS-50?
