*Just my 2 cents worth, take it for what you paid for it*
The 'Rifle' is the least expensive, or to be precise, the barrel.
Most guys to through a bunch of rifles at first, then they just see a gun smith and/or rebarrel since they don't want the cost of fitting a new rifle, trigger job, ect.
If you are you are going to get 'Kicked' 1,000 to 2,500 times a week, don't be one bit afrade to saw off the stock to fit you and install a recoil reducing butt pad!
The older I get the more I like 'Gel' butt pads!
You are looking at a good spotting scope & stand.
The $68 versions aren't going to do it.
Top end spotters are not cheap.
If you are going optics, do a LOT of research!
Not all optics are created equal, and the prices aren't cheap.
Put money in SOLID rings/mounts, you will be suprised how knocked around, what weather you will be in.
If you start throwing 2,500 rounds a week down range, a provressive reloader is a good idea, there goes $1,500 to $2,500...
You will like the time savings with progressive over any manual.
Unless you have a sponsor that provides ammo, reloading is pretty much a must.
I suggest you find someone that can teach you how to shoot long range.
Its a learned skill, and its a perishable skill...
Working out things like keeping the rifle square, keeping your body inline with the rifle, ect is something you need a coach or video for since you can't see your posture while shooting.
If you don't have an accessable 600-800 yard range handy,
Consider finding a farmer you can lease from.
Locally, its 200 yards for public range,
I use a fence row for 600 yard practice.
Doesn't give you the noise competition will have, but good to work things out.
If you are reloading, the caliber you pick isn't a huge deal,
But I stick with calibers that have a HUGE selection of ammo available about anywhere,
As above, .223 Rem & .308 Win have HUGE selections.
Others can be quite limited in a lot of places.
When you go to shoots, look at who is winning and what they are running.
Usually, half will be running the same stuff, the other half will be mixed.
