Sighting in rifle

[tef]

I hate to ask this on here but I know someone will help! lol. When sighting in a rifle @ 100yds, is it best to use the highest or lowest power? I do know that point of impact is diff. when using each at longer ranges. I always opted to use middle range, 4-6x, but friends are telling me highest and other the lowest. idk. Thanks

Wrong! Power of scope has nothing to do with point of impack.

Read your ballistics charts that correspond with with a particuliar scope and ammo. Nikon has one on their web sight. If you shoot over 100yds at same target on 3x, then use 9x, it will be several inches off. Granted it's just 4-6 inches, but it is diff.

[lameduck]

Olny if a scope has a paralax problem. Then it'stime for a new scope.

I'm sorry but you are misinterpreting something. The zoom has nothing to do with impact point. If you have a bullet drop comp reticle the zoom can affect the reticle only basically making distances between dots or lines worth different values.

[Sippy]

zoom has nothing to do with where your bullet will hit at all, other than you can pinpoint a spot at higher magnification

I always sight in on the highest power whether 9X,10X,or 20X and have never had any problems. I agree with above POI should not change.

Use the highest power setting to sight in your scope...It makes it much easier to shoot good tight groups.

The POI does not change with ther setting.

One sign of a quality scope is that POI does not change. Sight it in at the highest setting.

Dito...for peace of mind try multiple diffrent powers. It will not change the POI but it will give you a better working knowledge of you and your scopes capabitlities. For a sugestion, sight it at 100 yrds. then move to 200 and back to 50 yds. don't make adjustments if the 100 yrd. groups are tight, but again it will help you learn the capabilities includind bullet drop and rise. Good luck. Keep us posted...

i had a cheap scope from years ago that would have the impact change at different yards if the power was changed. but after its replacement and all others that followed never did. i gave up on that wifes tale from hunters that just did not make the shot. [blame the weapon, not the one behind the trigger.] say if you sight in 2 inches high at 100 yards, so that the round will be dead center at 200. that round may be off half a inch or more left or right someplace between the muzzle and two hundred yards. i guess what i'm saying is thats a round, not a lazer. from hookt it above, set the scope at 4, 6, 9. at 100 see if it changes. what will it cost you? better to find out today than the last day of season. jmht.

I use the highest magnification(9x in my case) for sighting in then may try a couple of shots at the other settings just to be sure... I seem to shoot just as well with 3x as I do with the 9x so it is just a matter of how much do I want to see in the scope view...

[tef]

Thanks for the help.

Sight it in on highest mag. But confirm that P O I doesnt change on lower mag.

Had to send a Zise 3-9 back for changing P O I from low to high mag. you can get a bad scope even with a top brand so its best to check.

I think that thing on nikon's website is probably in reference to using their BDC system, it's not talking about conventional scopes.
