I believe there is enough blame to go around to the manufactures, the distributors, stocking dealers and consumers. At one time you could, or had to, go to a dealer/lgs, look up a mould in a catalog, then order it. Few dealers could afford to stock all there was available, so just a few of them stocked the most popular moulds, and a few casting tools. Then it seemed for awhile, the actual manufacturers let the dealers deal with the public and didn't sell direct. It was even tough to get catalogs listing their products. If the LGS new where a certain mould was at they could get it but meant a lot of time tracking it down. Remember when it took 3 weeks to get a mould or gun part? Most dealers/ distibutors didn't/ don't have any idea an alloy can make any difference to the final diameter, and few had anyone in-house that did. Took a pretty well informed LGS to have a mould, sizing die, and top punch to fit, in stock, at the same time. We are pretty spoiled now! Get on the puter or phone, order what you want, with what alloy you expect to use, and it will be in the mailbox in a week or less, with the correct top punch and sizer!
