What brand of dies do people suggest, or is it down to personal choice?
Bit of a can of worms and budget dependant
I bought Lee everything for my 4 calibres, .223, 6.5, 5.5 and .303.
I was purely neck sizing with the Lee collet dies but every now and again they stick internally and you end up crushing a case. It was also very tough to get consistent neck tension.
So, I thought I'd give full-length sizing a go and it was awful, tried different lubes and they weren't the problem, I had to put so much pressure on the handle on the way down and up, I thought every case was going to stick.
Then I moved on and got Hornady K31 specific dies and some Forster dies, the difference between them and the Lee is night and day, buttery smooth resizing, you still need to put some effort in but nothing like with the Lee dies.
I want to try Redding but I can't find them in the calibres I want.
I will move to bushing dies for 6.5 at some point, but I haven't yet.
So, if you can afford it buy Forster or Redding, then Hornady are cheaper but still seem good. If you are cash-constrained then Lee will work OK, (I've loaded over 3k rounds with mine, and had 33 crushed cases), there are all sorts of articles on the internet about polishing them internally but I don't want to do that.
As for presses, I think any mainstream press will do, I have an RCBS and a Lee classic cast, the Lee gets the most use. If you have the Lee breech lock or Hornady lock'n load, then you don't really need a turret press but no harm in getting one if you want to.
After that, it's just a case of getting on with it and refining your process. I used to use a Frankford Universal Bullet seater, which worked fine, then I got all the Hornady OAL gauge bits and started to understand seating depth, at which point I set up a separate seating die for each calibre. Don't get too wrapped up with this when you start, just load to COAL and vary only your powder within safe published limits. Once you have a good powder load, you can start playing about with seating depth. If you only ever change one variable at a time and start with the simpler ones, you will be fine. For me, I'm at the refining neck tension stage, so it may be time for some LE Wilson dies and an arbor press with a pressure gauge, which will lead on to bushing dies.
