My 25-06 likes berger 115 bullets with H-4831, win brass and br-2 primers, three shots touching almost always @ 100yds when I'm on. For dies I use the Hornady custom grade about 40 bucks or so and a Lee collet die around $20.00. For 25-06 powders keeki just about named all the ones you would ever need. H-4831 may be the best one to start with for the 100gr. and heavier bullets my thoughts anyways. Also buy yourself a bullet comparator for measuring bullet seating depth I the ones from Hornady that attach to your calipers. This (your RCBS kit) is just the tip of the iceberg as they say, hope you have some extra dollars from time to time cause this where they will start going.
