Ok. I have a couple questions. As I understand, the advantage of the bushing style dies is they allow you to resize the neck as little as possible, without an expander ball. This improves concentricity and thereby accuracy. Is this correct? The advantage of the competition seating dies is they have a floating sleeve which allows for better bullet - case alignment, and the bullet depth is controlled by micrometer adjustments, making them easier to set. Is this correct? What is the advantage of the neck and body set, compared to the s-type full length set with competition seater? Price for Reddding competion rifle dies = $200+ and $64 for bushing set. Does this sound right? I have a factory Winchester in 270 win. This rifle will shoot Remington premier core-lokt ultra 140's (factory ammo) into 5/8 -3/4" at l00 yards. I want to shoot long range 500-1000 yards with this rifle, as I believe it has the accuracy potential necessary. Are the competition dies necessary for shooting these ranges? I was under the impression I could produce superior- to- factory ammo with standard dies?
