Methods For Sighting In Your Rifle...

What methods do you use when sighting in your rifle scope? I recently purchased a Led Sled. Hopefully, this will allow me to produce more consistent groups ensuring that my scope is adjusted properly.

I have a few questions for you veterans...

1. Do you begin by sighting in "Dead On" at 25 yds.?

2. How many inches above bulls eye at 100 yds. have you found to be most consistent? 1.5", 2" ?

3. What power do you set your scope to when sighting in? How does this affect things?

My scope is a Burris FFII Tactical with the BallisticPlex reticle. The instructions with it suggested that I sight in dead on at 100 yards for the hash marks to work. When i sight in my rifles with just a standard reticle, I usually sight in 1.5-2" high at 100 yards. That has served me well on shots out to almost 500 yards depending on the rifle Im using. Ive always just left my scope on 9 power or the highest power when sighting in. Just makes it easier to see where i want to hold and hasnt effected my accuracy.

I'm using a Nikon ProStaff 3x9x40mm w/BDC retical and sighting in as I have always done was to group 1" low at 25 yards. Then move out to 100 yards, where normal hits were 6" high and about 6" right. I make my corrections to be dead on at 100 yards. The second circle down is at 200, then 300, 400 and finally 500 yards.

Know your caliber and scope, and you can sight in dead zero at 100 yards. Alot of guns are out there with scopes not intended for their caliber that they are using.

1 Yes I start out sighting dead on at 25 yards.

2 I then move to 100 yards and sight dead on there. Unless I will be hunting somewhere that shots could be longer than 175 yds.

3. I set the scope at the highest setting. In most cases that is 9 power. The reason for this is that if you are dead on at long range as you dial down for closer range, any variation will be minimized by the closer range.

1. I shoot a 3 shot string at a 25 yard target through the chronograph for a baseline muzzle velocity. I will make very rough adjustments between each shot to get me "in the ballpark".

2. I choose a "zero yardage" depending upon what rifle I'm shooting and what I will be doing with it.

3. I run the load through a ballistics program to see where I need to be at 25 yards.

4. Zero at 25 yards using the ballistic info.

5. Double check at the pre-determined "zero yardage" and make any final tweeks.

I like 1 in high @ 100. Let me give you a quick tip to save some ammo.- hold dead on @ whatever yardage you choose, & fire. then anchor the rifle solid in your lead sled with your crosshars on the hole you just shot & without moving the rifle, turn the crosshairs to put them back on the bullseye, & you will be dead on in 2 shots.

I am in the dead on @ 100 yds for my everyday deer hunting rifle. Here is the reason:

I cannot say that I have ever shot under a deer. I cannot remember ever taking a shot over 200 yds @ a deer, because I am not willing to tote a rifles that is that big or has a sope with that much magnification around all day. When a nice buck comes in it is hard as **** to remember to aim low, most times you will put the cross hair on him and shoot.

My .257 Roberts hits about 4" low @ 200 yds, that's cool with me. Folks in the West may feel much diferently.
