I am new to this list, but have lots of posts on Gunboards, under "Kari Prager", a good seller's review from RCArms, also on Gunboards, and a great reputation on eBay under "scrmblerkari", just for bona fides.
I have 500 rounds of new and once-fired 451 Detonics Magnum brass. All are in original boxes. Make me a one-shot offer, I don't want to haggle, and please be realistic. (e.g. no 20$ offers). Any method of payment is OK except credit cards, (I have no way to process). I will hold personal checks until they clear. Prefer cashier's check if possible. I know the provenience of these rounds, they came from a good friend and he is the only user, so I am confident the once-fired brass really is just that. You can reach me at kari@calmoto.com, or my cell phone at 650 868 0269. If this is not the appropriate place for this, I apologize.
