Need Help For Hunter Ed Project

I am putting together a cartridge board of different .30cal cartridges for my Hunter Ed classes. I am only missing four:
.30BR (I can neck up a 6mm or a 7mmBR)
.300Whisper (I can neck up a .221)
.300 H&H Magnum

None of them need to be usable, Berdan cases are fine. I just need to be able to polish and mount them without bullets or primers. I am more than happy to pay postage. Please PM me or post with what you have and I will PM or email you my mailing address.
Thank you for your help.
