Gentlemen, Thanks for all your responses and information to my post. Albertan, Thanks for your info on the loading manuals and about contacting Lee about the factory crimp die. I will check these out, especially the Woodleigh manual. I use imperial sizing wax for all my reloadings and use the stainless steel media for all my tumbling. I have an annealer machine but need to see if they make a plate big enough to handle the larger case size. I have noticed on the first firings that the case mouths are no longer square. The case mouths grow at about a 5-10 degree angle after resizing. I trim them square again using an RCBS large capacity case trimmer. Lots of good information from all and very well appreciated.
