sighting in a new rifle

Does anyone have a procedure for sighting in a new smallbore rifle at, let's assume, 25 yards?

Is there a better way than just aiming at a target to see what happens and adjusting from the fall of shot? I guess I'm not sure realistically how far off target the sights could be - I don't want to start unnecessarily damaging target backing boards.

For example, is there a method for "bore sighting"? On the assumption that the trajectory is very flat at 25 yards, would it be helpful to clamp the rifle and align the bore with a target and then adjust the sights so that they are aiming at the target too (perhaps moving the rearsight up a bit to allow for some drop in trajectory)? Likley to be pretty rough and ready but may give some indication of where the first shot might go!

Alternatively are there measurements for the height of the rear sight and foresight above the bore line? (I reckon I should be able to get the windage pretty accurate by eye.)

I haven't got it yet but the rifle will be a 1913 barrelled action. Sights are likely to be the standard Anschutz foresight (no extension) and a Centra rearsight.

Any suggestions gratefully received...

Cheers

Nick

1. Set rifle on bench
2. Remove bolt
3. Look down bore and align with target (from the breech end)
4. Without moving the rifle, adjust rear sight.
5. Repeat 3-4 times


When you sling up, your point of aim will change, you will have to adjust from there.

This will save you 5 rounds of ammunition.

Find a convenient street light at night. and bore sight with that. It is easy to see when the bore is aligned.

Thanks for the replies. I think I will put it on a bench to bore sight it. Probably not essentially but nice to know roughly where the first shot will go.
