Even with today's more modern factory ammo you are at a slight handicap by not reloading. Is your 270 a shooter now? Will it shoot sub MOA? Do you have confidence in it when you take it to the woods? If the answer to these questions are yes, you might be just as well off buying new optics and a few cases of ammo to practice with. If you think its too heavy you could always have it bedded in a composite stock to lighten it up. Hornady has a 145gr ELD-X for Precision Hunter line. You might pick up a couple of boxes of that and see how it shoots in your rifle.
You can always get a Sako Finnlight that weights 5 1/2 lbs in 300WM and be good to go. Benching that gun will be hurtful so be prepared.
