more then adequate for 300 yards, i know folks who use their 22-250s for 400-600 yard pest controll.
are you planning on using this gun for hunting exclusively? because if you plan on doing target shooting or fun plinking with it too, the 22-250 is a bad choice! Why? Because after 4000-6000 shots at the latest, your barrel will be gone. If you shoot 50 rounds a week, after 2 years the barrel is worn out, if you shoot 25 a week you have 4 years and so on.
I had a 22-250, a cz, used it for long range plinking, after 9 months accuracy startet dropping from sub moa to 2-3 moa. i took it to the gunsmith, he took a look down the barrel and asked "how many rounds have gone down this barrel" me: "roughly 5000" he looked at me lifted an eyebrow and said "and youre wondering why accuracy is gone? Son, thats a 22-250..."
