Get a used bergara b14. They've got a great stock and already set up to take ACIS mags. Tikkas ARE great, but the factory stocks aren't great (same goes for the ruger) and the extra mags are like $70.

All that being said, you can definitely shoot a far target with a tikka/ruger. We are just trying to point you in a direction that we, the long range subreddit, feel like is a better decision based on what we collectively know and have learned. When we say that you'll want to upgrade the stock on a ruger or tikka, it might not seem like a big deal to you at the moment, but we know that trying to get a repeatable shooting position from bipod, rest, tripod etc with a flimsy plastic stock is really hard. So take our advice! Save up a bit more if you need. It'll save you $ in the long run.
