I have alway used RCBS dies for my reloading. When i have neck sized, i have just backed the die off some to size just the neck, and had good success. I have noticed these L.E. Wilson dies that are supposedly for benchrest shooters. Has anyone used them before, and are they that much better. I realize you need a different style press, and it looks slower, but is it that much better for accuracy? I'm getting ready to play with a 220 swift, and was looking for some input from someone who may have used both. Thanks from the new guy on the block.
