Of everything I own I'd have to go with the FAL I just got.
I once saw a program where they tested the ballistics of silver bullets. The bullets did not engage the rifling well at all. If ballistic tipped, copper jacketed, fragmenting silver bullets could be had, to me, those would make the perfect werewolf control round.
Cool thread!
I wonder how a Sabot round would work
Or a lead hollow point with a silver rod in the middle that has part of its end exposed in the hollow
