I'm getting frustrated and can't make a decision. I'm trying to decide on a caliber for benchrest and varmint shooting. I want it to be capable out past 500 yds. The two I keep coming back to are the .243 and .25-06. Keep in mind, I'm a beginner when it comes to precision shooting. This would be a rifle for me to learn and grow with. Well, let me have it. Thanks!
