The Forster Coax is what I have and it's an awesome press. I would recommend adding the Inline Fabrication short roller handle to it.
These are just my recommendations and equipment that I like the best. The explanations are brief but I hope helpful in seeing why the tool will help you. Not all of these tools are necessary to get up and running. some of them are to fine tune the load.
Scale: A&D FX120i with the Omega Powder trickler, Then you can also add the autotickler to the A&D FX120i to increase your loading speed down the road.
Powder Funnel: Satern powder funnel I prefer these to the universal type.
Loading Blocks: Frankford arsenal, I prefer these to the universal type. I use 2 in the loading process.
Case Trimmer: Giraud Tri-Way Trimmer. This will trim, chamfer and deburr the cases and save you lots of time.
Reloading Manual: Whichever companies bullets you plan to shot most.
Primer Pocket Cleaner: I like the Hornady primer pocket cleaner chucked up in a drill.
Flash Hole deburring tool, Not necessary on brass such as Lapua but if the flash hole was punched out (Hornady, Fed, Rem, Win, etc...) this will remove the burr and give a more uniform powder ignition which helps achieve a lower standard deviation. Only needs to be done once for the life of the brass.
Dies: Redding competition dies or Forster benchrest dies or Windham dies (comes with a shoulder bump gauge for setting dies up properly) I prefer full length sizing dies
Shoulder bump gauge: This will help you set the dies up properly so you're not oversizing the brass
Priming tool: RCBS automatic bench priming tool. I like using this more than the hand priming tools.
Calipers: Any of the reloading brands should do. I prefer dial just because the battery always seemed to be dead when I went to use the digital calipers.
Deprimer: I use the Lee decapping die. Not necessary to do as a separate step as the resizing die will pop out the used primer. I do it because I wet tumble my brass.
Tumbler: need this to clean the cases. traditional or wet it doesn't really matter neither will produce a more precise end product.
Hornady overall length gauge: This will help you find the best bullet seating depth for your rifle
Hornady comparator: You'll need this for the overall length gauge because you don't want to measure from the base to the bullet tip. This will allow you to measure from the bullets ogive which is where you want to measure when setting up the bullet seating depth.
This is just a list of some of the tools I think will help you. I'm sure I forgot some stuff. There are more tools you can get such as a runout gauge, neck turning tools, etc. I wouldn't add these till later if you feel the need. Hope this helps.
