Getting sighted in

[9.3mauser]

Holding the rifle steady [it cannot move]

I've never been able to manage that.

To the Op, if you're intending to zero your rifle for 200 yds, then shoot at 200 yds. Close range sight in is only good for getting you on paper.

Here's the skinny on the 3 shot sight in. Shoot one shot at 25-30 yards. Observe where the bullet hole is in the target.
Holding the rifle steady [it cannot move] starting with the crosshairs where they WERE when you fired the shot, adjust
the scope crosshairs to the bullet hole in the target, and then down about ¾ - 1 inch below it.

Now fire a shot at 100 yards or meters, being sure you have a solid, steady rest, and repeat the scope adjustment as
you did at close range. You should now be at Point of aim at 100. You can decide your elevation at this time and adjust
the scope accordingly. [say - 2" high at 100...move crosshairs down below bullet hole by 2"] Now fire one shot to verify.
You are now ready to go at 100, and probably at 200 as well. For assurance, another shot, this one at 200 will offer proof.

Thats how I do it as well, it works.

I was shooting a 270win 308win 30-06win and 300wsm and I did bore sight them in first then brought them to probably about a inch high at 25 yards then was like 6 inches high at 100 yards so what you guys are saying is start low at 25 yards so your a bit high at 100 yards? So as of right now I sighted all my guns in at 1 inch high at 100 yards so I should be all good for deer season I was just worried that I might be really low at 25 yards now if a deer came in close
Thanks for all the reapplies I know have a better understanding and hope to use less bullets when sighting in the rifles
Thanks

Nothing at all out of the ordinary then. Assuming a scope height of 1.5" over bore and given the calibers you listed, being 1" high at 25 yards will put you about 7" high at 100.

If you're zeroed at 25, you'll be about 3" high at 100 and zeroed again at about 250.

1" high at 25 is like a 15 yard zero, no wonder you were high at 100. The closer you bring the first zero in, the higher the trajectory relative to line of sight will be.

Get a ballistic app like Strelok. Spend five minutes putting in your rifle particulars and you can play around with the numbers to see what the effects are.

There shouldn't ever be any need to zero first at 25, a halfway decent bore sighting will get you within 3 or 4" at 100.

I always bore sight by putting the rifle on something sturdy and solid, remove the bolt and align the target in the middle of bore by looking through the action.
Once the target is centered in the bore I adjust my scope so the crosshairs are also centered on the target.
Works every time and saves ammo.

Yup. Every bore sighter I've ever used is far less accurate than just eyeballing it. Obviously I'm not suggesting doing it but just eyeballing down the bore can get you close enough that it would have been an effective shot on a deer at 100 yards.

Thank you Dave,
Bore sight at 25 yards and fire one shot at 25.
With the crosshairs on the original hold and the rifle dead solid move the cross hairs to the bullet hole.
Fire one shot at 100 yards or meters and now adjust so the POI is 2" high.
Fire one shot at 200 and make fine adjustments.
Just don't see wasting any ammo at 25 and 100.

I follow the same regime and it cuts down the walking LOL
