I have just acquired 2 Pacific 266 machines, they were new old stock, in original boxes. A 20g, and a .410 g. I thought I could load 2 3/4" & 3" on the 20g, and 2 12" & 3" on the .410...Not so. You have to have another crimp die body for 3" cases ! So I contacted Hornady, gave the correct part numbers, only to be told they are out of stock, and will not be re-stocking in the future. The DL-155 machine, and the DL-366 machine have the same part numbers, so I thought that Hornady would surely have these parts. So I will have to get a machine shop to make me the parts. Expensive, but necessary. Here is where you guys come in.....if you have the 3" conversion crimp body dies on your machines, could you give me the length of them? I don,t need any other dimensions... Should there be any for sale, I,m going to post this on Want To Buy Thanks Dave
