Max, Sinclair International is another wonderful place to see what BR shooters use. Just keep in mind that this is for BR rifles where a few thou matter. For most other applications, the rifle will never see any benefit using this stuff.
The best investment you can make is a concentricity guage. Without one, you cannot check how good or bad your ammo is. Sometimes even the best dies make wonky ammo.
Here is a link to a reloading article I am finishing up for the LRhunting forum. will give you the highlights on what I feel matter. Low runout, good bullets the barrel likes, tuned powder loads weighed accurately, lit by a match primer in fireformed/sorted Win brass. That'll will get you shooting into the 1's and 2's if the rifle is up to the task.
