I may be wrong, but I think Eley stopped production of eight and four bore cartridges in the 1980's and they don't manufacture them anymore. Bonhams sold 49 4 bore cartridges for £750 or $1,200 or thereabouts in July 09 (Forty-nine 4-bore cartridges, including forty-three cartridges by Eley-Kynoch in their original cardboard cartons along with one by Eley Bros and 5 reloaded cartridges). $65 a cartridge therefore does strike me as pricey.

Alan Myers, here in the UK, makes new 4 and 8 bore cartridges to special order, but I have a sense the price is considerable. Again - happy to be proven wrong here - but I thought they were getting on for £25 each new, or £500 per box. I saw a couple of boxes next to a brand new H&H 4 bore recently at their shooting ground here in London.
