Thoughts-
-the doofus who said don't even reload for that rifle? ignore him for the rest of your life.
-you're going to love how much more accurate your rifle gets once you find a load for it!! I'm using a 2007 M14s, btw, fave load (so far) is 42.7 grains IMR 4895 powder, a Hornady #3037 (150 gr FMJ), CCI 200 primer (actually had a slamfire with Federal once! never again...), and whatever brass I've go (I've got Federal, Winchester, IVI, DA, Norma, yup, I'm a scrounger.)
-read up! Choose a reloading manual, and read it thouroughly!!
-lots of good advice above about what to get, so I'm not adding to it.
-take your time and be sure about whatever you're doing, such as 'making certain that you have powder in a case before seating it's bullet' types of things. You'll eventually develop a rhythm that'll help you not make mistakes, but let's be safe at first, eh?
-yeah, if you're using NATO brass you're going to have to deal with the primer crimp; no need to crimp your primers in, but this crimp can really be a pain in the ash when pressing a new primer in... I just use an RCBS or Lee chamfer tool, end of story.
-hmmm, boxer primed milsurp brass is all I've ever met...unless it comes in case-lots from eastern europe or is super old (like WW2)... ...just be sure to check for the one big centred hole instead of two smaller holes side-by.
NEXT!
