Boomtube, I agree that at certain levels of experience certain tools and gadgets are overkill. Some remain overkill forever I think.
I'm still at the learning level too (as we all will be forever). That said, I feel I need the best ammo to learn from shooting. I must know why a shot went where it wasn't intended to as best I can. I don't want to wonder about the ammo.
I also hate to spend good money more than once on tools to do the same thing (although that still seems to catch me from time to time with poor quality and bad choices as I point out below).
Anyway, I recall some very useful posts from you regarding setting up of dies and choice of dies to minimise runout. You can correct me if I'm wrong, but I did a search and found the thread regarding your use of Lee Colletts (modified or "as is"), Lyman M dies etc. I can't speak for you, but it seems that you actually prefer the Collett dies and body dies as well. So I hear you (and agree) regarding value and what's necessary at a certain level, but I doubt what you recommend is your first choice at your level and I'm not sure your post makes that distinction. I'm not doubting that you answered the question as it was asked; you certainly did, but 5 years is a long time if you intend to seriously get into shooting.
Runout with regular dies is a real problem - and one I'm experiencing again now using them in a few chamberings (luckily for short range shooting).
So my advice, ISU, is do the maths and decide if you are in shooting with your 300 WM for the long haul and then decide whether you want to save $40 or $50 that I suspect you'll wish you spent later.
The fact that you are on a "Long Range" forum and your username makes me think you will take this seriously enough for the slightly more upper end equipment.
I recently bought a Lee (2X in fact) sets, a Deluxe and the one with the Taper Crimp and the full sizer in 375 H&H (whatever that's called as a set). Both were fairly unsatisfactory and the Collett set (? Deluxe I think) with the dead length seater is in my opinion a total failure. Maybe they are better in other chamberings, but the seater die body is too short for the 375 IMHO. I'm not simply knocking Lee as I use them in various calibers, but by the time I'm done here I will wish that I kept the Forsters I had originally as all the buying and selling (assuming I can do this once I explain why I'm selling a brand new die set) will cost me more. As I'm in South Africa the Lee guarantee is a lot harder to try to call up and with shipping, customs duty, return shipping etc. I'll be down anyway.
