I'm with tricky on the co-ax press and forster dies. You can't beat the lee collet neck die followed dy a forster bullet seater but the co-ax press is 2 1/2 times what the whole lee kit is and the forster set is $92.00 alone. The lee kit will get you about 97% of the accuracy. To get the last little bit is a fortune in tools and time. Get the lee kit and the few other tools and start. You will get addicted and it will be easy to upgrade later.
First of all the average guy shooting a .308 will never shoot over four or five different bullets, and many will never do more than three. You really don't just have to have the micrometer head on the seater, and always remember you can add it on later if you so desire. If your turning necks and then sizing off a bushing, I think I'd go with the Redding "S" die or the Lee Collet die. Then just buy the Redding body die to push the shoulder back a couple thousandths on an inch. The nice thing about the forster is that once you have the lock rings set, you cab forget ever needing to move them again. The priming device on the Forster is better than any I've ever seen on a press, and is better than 85% of the hand held devices.
Another option that is probably going to run you about the samekind of money that the big Forster press and dies will cost you is the buy the following:
1. A Lee cast iron press
2. A Redding body die
3. A Forster N.M. .308 sizing die
4. A K&M arbor press
5. A Wilson .308 bushing die and seater
6. A K&M priming tool
7. The Hornaday gauge set
8. a good pair of digital calipers (Mitutoyo, B&S, or Starrett)
9. A Wilson case trimmer
10. As an option, you might add the Forster seater.
later pick up a NECO case gauge without the dial indicator, and look for a B&S Best Test indicator in .0005" readings. Also buy a good pair of 1" micrometers, and learn to use them.
The setup I layed out will make better ammo than any of the presses, and with it you can load at the range. What you choose for a measurer is your call, but I think I'd just buy a new Lyman off Ebay and add the Sinclair bottle adapter and a couple drop tubes. You'll still need a trickler and a scale (I ain't going into that quagmire again). You can buy the Lyman and all the Sinclair stuff for about half the price of a good Harrell (the best). If you decide to neck turn later, then buy the K&M tool (one of the very best)
