Life made easy,
Patsreloading has Hornaday 168 match HPBT for $139 per 1K
Gibrass or Pats for pulled down unfired LC cases. (if you don't plan on shooting match, pats has unfired RA61 pull downs for around $60 1k.
Primers, either Fed 210m or Rem 91/2
Powder, I use 42.2g of 4064 to 300, then 43.1g (compressed load) for 600. Your gun will differ, so plan on working up loads to see what make the rifle happy.
Best to load the LC cases at 41.5g and work up for your short loads, then start at around 42.5g and work up for your 600 load. Just remember that the LC/RA cases are military and do have reduced a volume than comercial brass, so that means less powder for your start point.
P.S. using the above componets, your looking at around $.37 a shot. Plus, you didn't say what barrel you are getting, so on the short range loads, load for the mag, then on the long range loads, Long load to just sit off the lands (read single loaded).
