Look at some reading materials by Tony Boyer, Mike Ratigan, David Tubb, Dave Brennan, Frank Pearman or others. They have some good information that might be of interest to you. Most of the chassis' type of rifles that you look at are good. A good bolt action rifle in a standard stock is another option. An entry level option might be a Ruger predator or a Savage 110 either of which can be bought under 1000.00, good optics properly mounted makes a world of difference, proper cleaning methods and care of your equipment there is so much more to it than just buying a rifle and ammo it isn't an overnight adventure. Studying, practicing and learning are all time consuming but are the best route to being successful in your quest while not getting frustrated and discouraged then quitting after laying out a bunch of money. You can go to youtube and look up some of the names mentioned above as well as looking at precision rifles, beginning bench rest shooting and a few other topics before you lay out your money.
