Tom, I've been collecting fired "rare" bullets for 30 years. But I'm not sure I've got a fired New Austrian. I'll have to go root through several jars and boxes to see if I do.
What other types might you be interested in?
I've also collected non-rare ones that just look "interesting" -- for reasons like showing rifling-marks really well (and also showing which firearm-type they were fired from) ...or for unusual shape, such as fired minies that tumbled and struck butt-first, creating the appearance of hillbilly-hats, cowboy-hats, and a sombrero.
And of course, some of the "high impact" (a.k.a. very-violent impact) ones.
Email me about whatever types you are looking for, and I'll keep going through my jars and boxes.
Regards,
Pete
