OK. Welcome, you are in good company here. there are a few questions you have to ask yourself as you get started. how far do you want to shoot? (500-800-1000-1250 yards). the further out you go, the more $$ it takes. second, what are you shooting at (animals or paper: what kind of animals?) how much money are you able to invest up front and how much are you able to set aside monthly/yearly for improvements and practice. these are a couple of MY rules of thumb.
Start with a Remington 700 action (stainless is my preference) in a caliber that is close to what you are wanting to be at. (question#2)
Start reloading with good tools (RCBS, Hornady, Wilson...)
scrap the spotting scope up front an put the money into a better scope.
If you buy cheap stuff, you will always kick yourself for not saving a little longer to get something decent.
once you have a gun, get a good trigger (just spend the $200 on a jewel)
Next, port your barrel.
Next, get a heaver stock.
then get a custom barrel put on it by a reputable gunsmith (you will have to wait)
then get that really expensive scope because now your rifle desperately needs it)
once you get shooting for a while and you stay connected to this and other communities, you will know what you want.
Not to be redundant, but if I had to start over again, this is what I would do.
Buy a Remington 700 SPS for $550-$650 (the stainless one with plastic stock)
Buy a Jewel trigger
Port the barrel
Buy a Burris FullFeild II or a Nikon Monarch 5-20x50 ish scope in the $500 range
this gets you started for $1500 in Gun.
Buy 5 boxes of factory ammo for $150.00
shoot all those rounds to site the gun in and get a feeling for it. start at 100 yards and by the time you are done shooting the first 50, you should move to 200 and then to 300 yards. note your accuracy and shooting technique, breathing, flinching, eye closing.... all the stuff you need to watch to shoot correctly.
buy the RCBS or Hornady Reloading kit for $300.
After you get those rounds shot, reload them 20 at a time with some different loads to get some kind of an idea what kind of loads your gun likes. then, till you get through that second 100 rounds, you will know a lot more of what you are doing.
