I haven't found loaded ammo. I have Jamison 460 Weatherby Basis Brass that I reformed to 465 H&H. Woodleigh makes the bullets. I have several boxes of their 465 Nitro 480gr RN SN and have their 480gr Full Metal Jacket and 480gr Hydrostatically Stabilized Solids on backorder. I also have Quality Cartridge 465 H&H Magnum brass on backorder which is overdue.
