Dzscubie brings up most of the pertinent points regarding reloading.
if your time is not factored in, cost of components/100 determines savings after the cost of your equipment is amortized. i wouldn't advise anyone to buy a shotgun press as sophisticated as a mec 9000 at first. the 600 jr. will give you first-class ammo for 1/3 the up-front initial cost. if, after gaining experience you can justify the 9000, then go for it, but my guess is the 600 jr. will keep you happy.
an interesting thing about reloading is that the more knowledgeable and experienced you are, the less you'd need to expend on equipment if you were starting over. i'd replace my stuff with used to save money, but if i were a newbie, i'd go with entry level tools from suppliers such as natchez, graf's, widener's, midway, etc.
there's nothing wrong with with a starter press kit from lee to see if the reloading bug is real or just a passing thing...if it's real, the equipment will be useful even after your purchase of a dillon progressive machine; if its a passing thing, the equipment won't have burned a hole in your wallet.
the same deal holds with shotshell reloading...a mec 9000 is serious equipment...in my opinion only necessary if your time is worth lots. i have one, but the amount i reload would only justify the 600 jr. if i had to replace it.
if you pursue the hobby, order on-line, except for powder and primers unless you order enough to offset the hazmat cost. ups etal
charge a $25 adp (additional dealer profit
) fee for 100 primers to 25,000 primers, or 1 lb of powder or 32 lbs of powder...but that's a different string on the forum.
ignorance is its own reward
