Sighting in.

[oktx]

A month ago I sent my son's 243 back to NEF because there was some play in the action and it would not group.  I also asked for the trigger job. It should be back this weekend.  I had been shooting rem 100s, I bought Fed 80's and win 80's.  Which one should I sight in with and at what distance?  Should I just pick one to sight in and then shoot the rest just to see which ammo it likes best?  thanks, oktx.

I'd say it's a toss up.  Might sight in with cheapest and go from there.

I'd start at 50yds with a large target.  Waste far less ammo that way too.  Is it scope sighted?  Probably.

If so go for dead on at 50 and you should print about 1" high at 100.

Try the 2 shot method, it really works.  Shoot one, hold rifle on first point of aim and have someone adjust the crosshairs to intersect THE BULLET HOLE WITHOUT moving the rifle.  Now put the crosshairs on the bullseye again and you'll be very close.

Test for groups with both at 50 to see which you  and the rifle like best then go to longer distances.  You can accomplish a LOT at 50yds and not waste ammo looking for bullet holes.

Thanks handirifle,  After I shoot the first shot the gun obviously moves.  Do I just move it back to the point of aim and then have my son move the crosshairs?

Yes, that's exactly what you do.  Make sure you hold it where you AIMED first.  The tricky part comes when you have moved one of the crosshairs, as there is a tendancy to re-align it.

Just hold the rifle firm to the stand (VERY important) and let him adjust.  You'll have to tell him if it needs to go right, left etc.

Like I said, this will get you very close and you can fine tune it from there.  Saves a lot of ammo.

Some scopes have a tendancy to "hang" when adjusted so you might need to "tap" it lightly at the adjusters to make sure the crosshairs have settled.
