I recently purchased some Winchester 209 primers as my standby Remingtons were not available. While the Winchesters will seat ok in an STS hull that has been reloaded several times, they will not seat properly in a newer, once-fired STS hull. Also, the Winchester primer seems to be a bit longer than the Remington 209. Is there a fix or are the Winchesters basically incompatible with the newer STS hulls? I use a PW 800 Plus, and have attempted to adjust it slightly to seat the primer deeper, but with little success..I don't want to over-do it on this adjustment as I suspect doing so will cause other issues. As it is now, about 1/2 are pretty much fully seated, and the other 1/2 aren't.
