Do what I wish I would've done. I don't know what rifle you currently have, if it is a good platform, for about $600 rebarrel it in 280ai, 6.5x284, or straight 284, with long bullets in that long action. There are some great bullets and powder for those combos. I think you will like a custom barrel. Spend the rest on a good scope that you can keep for a while.
Spend your future money on reloading supplies and shooting experience, When your your done growing, you'll be ready for a big caliber, which can get expensive, but still have a great mid-range gun that you will most likely carry on most of your hunts because a lot of guys are loyal to their first rifle that they learned on.
Plus almost everybody needs a 6.5 or 7mm of some sort in the safe.
You will get a lot of people telling you that your 270 shoots great, which it does. But I have seen alot of 270's and 25-06 shoot 1 1/2 inches at 300 yards and then throw up 6-7 inch groups at 400.
Good luck, you WILL get hooked.
