Im sorry if this is in the wrong place but I was wondering if anyone knowledgable could help me out. Im looking at dies for a custom made .300WM (PSR/Long range paper puncher) and I’m not sure what to get. Iv only ever used Lee FL dies before for .308 and i got pretty good accuracy (around 1/2MOA) but i want to squeeze as much accuracy out of this new long range gun as possible. Is there any difference in accuracy in the competition dies that are FL Sizing, FL Bushing, Neck Sizing, Collet Neck Sizing (Lee), Neck Bushing (Redding), Bump Neck Sizing(Forster)...?

Any help would be appreciated as to what approach to take to reload as accurately as possible for this gun. I’m stuck on the advantages and disadvantages of these die systems, and quite frankly what do they offer over a regular FL sizing die? Accuracy and easy of use are my main concerns. Its a bolt action and brass will be used only in the one gun.
P.S I do case prepping already so no need to add that to "to make it accurate..." and i really have no interest in an approach that involves case turning.

Thanks
 
Lee collet die is the way to go, my 300WM is a 0.6 moa rifle and down to 0.3 on a good day. Also, I have the Lee set in 223 Rem, it 5 shot one hole group at 100m occasionally.
Lee will not hold you back, consider skim turning the necks it may help down the road.
 
I'll second the lee collet die ,easy to use no lube to clean .Since u don't want to turn ur necks it will keep the inside neck diameter the same regardless of the neck thickness .I also use the forster bench-rest seating die and I get low run out .5 of a 1000 on the finished round I use the redding body die when it's time to bump back the shoulder.
Everyone has their favorites
