Ive been using C&H dies, presses, powder measures and trimmers since the 1970's and although they've changed hands a few times quality has always been topnotch and i wouldn't be suprised to see the dies you want in stock.
I needed a set of 6.5x58R Sauer dies, a propriety German cartridge from the 1920's that is pretty rare, they had a set in stock including a bullet sizing die to take .264 down to .260 the old drilling will now shoot under a MOA at 200 yards.
