Bolt action rifles are very easy to sight in.
But you need some kind of support for the rifle, so it's solidly in place.
Set up a target at about 10 yds or so.
Then remove the bolt.
Looking right through the barrel, (from the chamber end, of course), center it on a small place on the target.
Adjust the scope or sights to the same place on the target.
And it's done, except for maybe some fine tuning for distance.
Shoot a few rounds to double check.
If the hole in the target and the scope/sights don't quite agree, leave the gun pointed at the hole and adjust the sight to the hole.
