Re: Die suggestions.
If you're getting a Redding Type 'S' F/L bushing die, I personally don't really see a need for the additional Type 'S' neck die.
Other die options include the Forster Precision shoulder 'bump' die, which uses their own flavor of neck bushings (instead of Wilson/Redding style), or the new F/L bushing dies from Whidden Precision. I haven't used the latter (yet), but based on past experience with John's products I would expect it to be top notch, and plan on getting a couple later this year as time/funds allow.
That said, in the past Redding Type 'S' F/L bushing dies have been my go-to solution and they haven't failed me yet. I typically tinker with other combinations, but I have Type 'S' F/L dies in *every* caliber that I load seriously.
As for the Comp seater... good die, but kind of spendy. In my experience, a Forster Ultra BR die compares favorably for considerably less $$$. The Wilson seaters are nice, particularly if you spend the extra $$$ to get the micrometer tops... but you'll have to pony up for a separate arbor press to utilize them. (again, I have all three options in various calibers). I'm not convinced that the Wilson dies seat the bullet any straighter, but you do get somewhat better 'feel' during the process - at least if you use fairly light neck tension.
