I agree it hasn't been shot much. The Lyman 48 sight is 1/4 MOA per click you will have to do the math for shot movement at the various ranges (distances). Shoot 40 grain, lead, Standard Velocity through it.
Aguila Super Extra in the Blue and Yellow trimmed box is good ammo at an affordable price. Federal 711 or 714 when available is decent ammo too. If you get real serious you can use the higher grades of LaPua, RWS, Ely, etc but they are Very expensive. The lower grades of them are great as well.
