Lee collet dies can be tricky to adjust so I am told. Crimp dies are for straight walled cases. I would get Redding Deluxe 3 die sets for each caliber. If these are to high, then RCBS is a good second choice.
I`d think you need to ask many, many questions, or find someoe who has a great reputation, not a wannabe, for good information on loading.
I only buy Redding dies, so that is my suggestion. Midway, Graf & Sons has them.
