They're heavy and...soft.
wich is actually a good thing.
They pack a bigger punch and deliver their energy to the target.
Less likely to ricochet back in my face.I'll be launching them at relatively close range.
Wich would actually be a bad thing...
despite the possibility if me becoming...less ugly because of it...

Over distance 1" steel sounds sweet though.
You could possible retreive them and use 'em again.
