This has probably come up a hundred times before, but where can I find a replacement cap for a Lyman 55 powder measure. Doesn't matter if metal or plastic. I checked ebay expecting to see sources for the plastic cap, but nothing came up. I know I can post in the "swappin' and sellin' " section (and will probably be my next move), but with as many of these measures out there and no support from Lyman, I would have thought others would be someone supplying this part.
