I would suggest you really put EVERYTHING you WANT down on paper and see what you really have. In just skimming through your posts, I would not really recomend any of this. Hopefully you are not planning on spending all the money you have on a rifle? I know every time I buy a gun and then order slings,bipods,bullets,powder,rings,bases,ammo boxes, dies,bushing,and all the crappie accessories I spend big bucks. Its probably always double what I plan. If you reload then you already have rifles, and my suggestion would be to get out and really use what you have at your disposal.
Buying a 20" barreled rifle is a waste for LR. Also scrapping the barrel and stock right away are very expensive. I dont think any 15 YO kids are ready for a LR rig. There are alot of more important things unless you just have lots of extra cash burning a hole in your pocket.
GUN 1200 ( maybe)
Range finder ($$$)
Spotting scope ($$$)
GAS to go hunting ($$$)
ammo bullets are about 25 per 100 and powder is about the same per pound
If I add the cost of the spotter, rangefinder and rifle scope that I have they add up to well over the cost of your rifle. I would try to be realistic, take the largest caliber rifle you have and set your self goals, ie an animal at 100,200,300,400 out to 600. After you have completed this and one year passes, then if you want the same things, do it. Just my .02
