I just bought my first Dillon SDB. The powder measure is and older model that doesn't work with the new 'bell crank update. It utilizes a screw, rather than a through bolt. It also doesn't have the roller where the bell crank 'arm' indexes the slide. Does Dillon use a common measure models, or are they specific to particular models? I am considering buying a used one off of eBay, rather than getting new parts from Dillon.
Or am I over thinking It? Simply use as is? Thanks, Tom
PS- been reading a lot of reading on this sight!
