Regulating a new rifle

I recently bought a rifle from a gunsmith that requires regulating the iron sights. I am not a gunsmith, but insisted that I regulate them myself. Although this is not the smartest thing I have ever done, I want to try it.

I am looking for ideas and references on how to regulate iron sights. Any feedback (other than take it back to the gunsmith)?
 
If it is a bolt action?? you can remove the bolt, sight down the bore and adjust the sights until whatever you center in the bore is registered as a 6 o'clock hold by the sights. HTH
 
First off, start your sight-in at 25 yards. That way you know you'll easily be on the paper.

You move the rear sight in the direction you need to move the point of impact of the bullet. If there is no screw-type adjustment, use a small hammer and a drift which is softer than the material of the base of the sight. Shoot once, tap, shoot once, tap, etc, as necessary.

For changes in elevation, if you need to hit higher, raise the rear sight.

You didn't say what cartridge, so I can't help you as to "Dead on at 25 yards = X" high (or low) at 100 yards (or whatever distance)."

Hope this helps,

It is a bolt action, but the rear sight is a flat blade, there is no vee in it. The way I understand rifle regulation is the process to actually file the vee into the rear sight so you have an accurate picture.
 
Art,

The rifle is a .416 Rigby. I am pretty comfortable sighting a rifle in whether I use iron sights or a scope. My concern (and maybe I don't understand the phrase 'regulating a rifle') is that once I take a file to the back sight, I can't go back.

I need the rifle to be accurate given what I hope to use it for, but I want to do this right the first time.
 
Never heard of a rifle that requires you to file the rear site...

Is the rear sight drifted in? i.e. can you drift-adjust it if necessary? If so, then your windage (i.e. where you cut your notch) is not so critical.

Is the rear sight (or front sight) adjustable for elevation? If not, you can raise elevation (POI) by filing the front sight. You can lower POI by filing the rear sight leaves.

Because you align the top of the front sight to the top of the rear sight leaves, the depth that you file is not important. Make it whatever depth gives you fast acquisition.

If you can't adjust for windage by drifting the rear sight, then the location of your rear notch is critical. I agree that the best techniques would be to bore-sight the rifle, then carefully _mark_ the location you want to file. Then test-fire, aligning the front sight with the mark. Elevation will be off (POI will be high), but windage should be correct. If it is, file there at the mark. If not, adjust the mark as necessary, and don't file until you have the windage where you want it.

Anybody jump in and correct me as needed.
