I've never shot this rifle before. Only rifles I've shot before are low-recoil (comparatively) .30-30 and 7.62x39. I want to be somewhat familiar with it before running off into the bush. Wouldn't you agree that was responsible?
If that is the case you can probably benefit from shooting a box or two for familiarization. But before you start, as stated on the other posts you need to bore-sight the rifle, with either a commercial bore-sighter or by looking though the bore and centering it on the target, then adjusting the sight until it covers the bullseye. This can be simplified with the use of a cradle which can be made simply by slotting a rigid cardboard box that will accommodate the rifle.
The next step is to confirm your zero with live firing and now comes the cool part so pay attention.
If you bore sighted at a longer range move your rifle and cradle to the 25 yard line. Assume a solid position either prone or from the bench and fire 1 round at the target. Place the rifle in the cradle and adjust the position of the cradle until the sight covers your aiming point. Without moving the rifle or the cradle adjust your sight until it covers the bullet hole. Move back to 100 yards and again fire a single round then place the rifle in the cradle and adjust the sight to cover the bullet hole. Depending on your sight, you may have to mark the bullet hole to be able to see it. Once your sight is adjusted for 100 yardsd, you may want to fire a 3 round group to ensure your adjustment was correct and that you didn't pull the shot you adjusted to. Now your rifle is sighted for 100 yards, but most cartridges do better with a longer zero range.
What you want to do is raise the sight so you bullet impacts 2" above you line of sight at 100, which is a fairly simple process with a scope sight. If your scope has quarter minute adjustments, raise it 8 clicks to gain 2" at 100 yards Depending on the velocity and the shape of your bullet this higher point of impact should take care of any trajectory concerns out to 230 yards or so depending on how flat your load shoots. But you've saved so much ammo during the sight in process that you can now afford to shoot at various ranges to see what the drop below or the rise above your line of sight will be.
Each time you shoot, write down the results. The difference between a good marksman and a superb marksman is often the records each has to refer back to. These records should record the date and time, weather conditions, light and the position of the sun and direction of the wind pertinent to the target angle, and of course your performance on the target. If you have a commercial bore sighter that uses a grid to adjust the sight against, you can also record the position of the sight against the grid for each load you shoot in the rifle, which will reduce the amount of time and ammo it takes to return to a previous sight setting.
