so i have a brand new leupold scope i want to take of my 06 and put on my 270 . outdoor emporium wants 30$ to swapp and baorsight it. but that involves bringing guns to work risk of theft ect. my question is does it need to be boar sighted? or can i just swapp them out and go to the gun range and re sight in? thanks in advance. as i have not switched scopes before.

I buy my stuff a local sporting goods shop and they install what they sell and will bore sight it for me free of charge. They will even assist me on stuff I buy eleswhere, like cabelas or Ebay. But then I spend a small fortune there annually  One of the benefits of not buying from a box store I suppose.
You don't necessarily have to have it bore sighted, but I'd recommend it, unless you want to waste a lot of ammo.
Most range masters at the range have a bore sight and will gladly help a brotha out. At least that's been my experience.

Sight the gun in at 24 feet. The bullet will hit the target in the same place as it would at 100 yards. If it's a bolt action, remove the bolt and lay the rifle on a solid sand bag rest. Look through the bore and center the bore on the center of a target. Then without moving the rifle, adjust the crosshairs to the center of the target. Fire one shot to make sure it is close and move target to 100 yards and finish sighting in, maybe five or six shots total should do it.  Bill

Yeah, but to sight it in for 24 feet, and it will be on at 100 yards is a bit of a stretch, as scope MOUNTS are made in high, medium, and low (in height) configurations, which translates into distance above the bore. So, even if WERE true for 1 configuration, that would prove off for the others.
The big thing is to sight in the gun at close range, say 12 1/2 yards, then check it at a longer range, where it will at least be on the target paper, and do the final adjustments on the longer range target.
But just remember, if the scope has 1/4 minute clicks (1/4") at 100 yards, at 50 yards, they are only 1/8" movements, and 1/16" at 25 yards, etc. This is important to remember when you are adjusting the scope.

Just toss it on, and use locktight on the screws. I start at 25 yards, but the idea is to get it close so you at least are hitting paper close to where you are aiming, and then move out to 100 yards to zero it in. If you don't have the tools, it is time to get them, good allen wrenches and gunsmith screwdrivers, might cost you $30.  Never used a bore sighter, ever.

I've never before heard of sighting in a rifle at 24 yards?
The standard method I was taught(bolt action) was to set the rifle up in a bench rest and pull the bolt and sight down the bore and adjust accordingly as pointed out by several people. Then fire 3 rounds at the bullseye at 25 yards. A single round doesn't always work to identify where your rifle and the round you are using will hit with some consistencey. I usually shoot a selection of reloads looking for that best round for me and the rifle. Others will just shoot factory ammo. Factory ammo is almost consistent in where they hit so just select one load from what you are testing for the initial shots. For reloads I select a load that is predicted to hit somewhere in it's middle range of feet per second. Shoot 3 rounds at 25 yards and then adjust to bulleseye ...you do not need to be exactly on at this stage...just hitting paper within a hand's space of center. BTW you don't use different rounds/loads during this process....I am acquainted with someone who shoots and reloads alot that does this.  Then shoot the same round/load at 100 yards. It's gonna hit someplace other than where it hit at 25 yards and yes 24 yards also. That's fine. After this you see if the chosen round/load will shoot an acceptable group...don't worry a bit about hitting the bulleseye other than using as a point of aim...don't do things like sighting a hair left on your 2nd or 3rd shots because your partner spotting yells that you are a hair to the right of bulleseye. Explore what this round or load will do in regards to pattern then evaluate others by repeating 3 round groups. Once you find that round/load that is grouping anywhere under an inch at 100 yards and you are satisfied with that being the round/load for that rifle and you it is time to simply target the rifle for elevation and center. Left/right clicks on the scope as needed moves it to center. Up/down clicks selects your deired elevation. I prefer 2 inches high at 100 yards for any of my deer hunting loads for my .243 Winchester. 3 rounds in a 3/4 inch or less group at 100 yards and I am easily good to go for any deer out to 300 yards and with a bipod for assistance I can do the same out to 400 yards. Past that I won't shoot as it's stupid to most likely wound and lose the animal. Ballistic charts will let you know where your bullet is predicted to be anywhere along it's path. Good idea to learn that. A pair of rangefinding binocs will also be of great assistance if you are attempting long range shots.

Gooose, If that remark was directed at me please read my post again. I said feet, not yards. Just try it sometime. it'll only cost you two rounds. Bill

Ok, I'll bite. 24 ft? Where do you measure to? I mean with 100 yds, a foot isn't a big deal, but I could see you end up at 22 ft really easiliy.

I read years ago in G & A it is at approximately 24 feet where the bullet's trajectory crosses the line of site. So it you are sighted in for 2" high at 100 yards, shoot at a target at 24 feet and it will hit two inches high. All I can say is it was true with a Rem. 700 .270 Win. cal., also one in 30-06, and a Ruger 77 in .338 Win. mag. I am not speaking of micrometer measurement accuracy, just approximate. So the 24 feet would be from the muzzle. The distance was actually 23.7???????feet as best as I recall. Bill

Goose,
Sighting in at 24-25' is one way to do it, and very accurate also.
In the Corps we would sight in at 24-25' to get a BZO and this works, it equates to the same trajectory at 100 yds.

Tony I surrender! If that is the way the Marines do it then there isn't a better way. I've over the decades used 10 or 25 yards. The goal is to simply find a load that groups accurately for a given rifle . Once you have a satisfactory group then it's simple to transfer the impact point of said rifle and load to 100 yards. I shoot a pre 64 Winchester Model 70 featherweight boltaction with a 22 inch barrel. The load I found as best for my shooting with that rifle uses a 95 grain Nosler partions and Remington cases...christ I forget the powder and grains as I have a reloading fiend as a friend who does that for me...I'll check on that. He just tells me how much money he needs and what fantastic loads he has for me to try out. Theoretically it will have a MV of 3250 fps which is smoking hot for the .243 but when I shot it on the range my rifle wouldn't produce satisfactory groups with the max load and found that a slightly less smokey load produced nice 3/4 inch groups from a bench rest at 100 yards which chronographed at 3150 to 3175 fps which is still smokey for the .243. Sighted it in to hit at 2 inches high at 100 yards which means it's gonna be hitting at zero elevation at around 240 yards. I'd have to look for my ballistic charts but for all intents and purposes that load made a shoulder shot out to 300 yards a dead deer. Hmmmm I need to give my reloading fiend a call!
We really need to start a reloading discussion!

Okay, the LATEST Marine Corps practice (to establish a "Battle Zero") on the most RECENT AR-16s now being issued is to sight in on a "minature D-target" at 36 yards. (A D-target is a silhouette of a person's head and shoulders. It is a "rapid fire" target resembling a guy laying prone to shoot at you.) This gives a basic 200 yard zero, and you can hit a man-sized target out to 300 yards. This practice has also been picked up by the Army.
I got this straight from my nephew, a Naval Academy graduate, and who just retired as a Marine Corps full Colonel.
When I served in the Marines (Korean War), the way we could short-range establish "Battle Zero" on the old M-1 "bullet launchers" we were issued was at a "1000 inch range." That equates to 83.3 feet, or 27.8 yards.
The reason for these changes? It's "height of the sights above the bore", and trajectory of the given round.
So, my advice is don't count on "rules of thumb" which work for a specific rifle. Just because they are good for THAT application doesn't necessarily work universally.
Not trying to start any arguments here, just some more factual information to consider.

Hey Bob,
I've been fortunate enough to shoot on the ranges at Quantico using those "new" Dog targets and it's quite a change from the days I qualified on.
I think it's a much more challenging course than shooting at A targets, as like you said, it's rapid fire. Still fun tho' to rip up some paper...
I don't know anything about marksmanship, but I did stay at a Holiday Inn Express last night

Well, with the ol' M-1, the course of fire for qualification in the Marines was ---
10 rounds slow fire, offhand (standing) at 200 yards at an 8" bull.
10 rounds rapid fire (you started in the standing position) sitting at 200 yards at a "D" target.
10 rounds slow fire at the 8" bull at 300 yards, 5 shots kneeling, 5 shots sitting.
10 rounds rapid fire (again from a standing start) prone at a "D" target at 300 yards.
10 rounds slow-fire prone at 500 yards. Bull was 36", but the "V-Ring" to settle ties was about a 12" circle in the center (if my memory is right!)
A perfect score would be 250. At the time, it would have been a range record. (And you would have been expected to buy the drinks that night!)
(The best I ever did was a 240.)
Marksman was 190 minimum.
Sharpshooter was 210 minimum.
Expert Rifleman was 220 minimum.

Nice hardware there Tony.
A friend of mine, who did his stint in the early 70's said his DI sent him off to get the 'group tightening wrench' and that would help his abysmal performance on the range. I could probably use one of them...

No arguments from me Bob. I appreciate reading both yours and Tonys posts about the Marine Corps. 8 inch target at 300 yards is definitely not an easy shot with open sights! 
Tony I am of Irish/Scottish heritage...not known to surrender like the French. BTW after shooting my fiends AR-10(?) .308 several years ago I've always had a desire to have one custom built with a bull barrel chambered for the .243.

sounds like a sweet gun to me Goose, I'd like one of those also
if it was .308, it was indeed an AR-10
Thanks W4F

The custom varmint bull barrel AR-15 my fiend let me shoot was amazing. Crack, crack, crack, crack for a 10 round clip of .223 reloads. Then we shot his AR-10 in .308. Blam....blam....blam for a ten round clip. Barrel jump was minimal and it was simply a matter of keeping crosshairs on target and touching the trigger. The AR especially in a varmint design is one magnificent weapon. I'd really hate to be the enemy target on the receiving end of the AR shot by our Marines. BTW I have shot nearly all of the military bolt actions used by the various nations who used them plus the german WW2 semi/auto rifles and the M1 and M14. The Italion Carcanos are the only ones I've ever found fault with. The Japanese Ariskas are bullet proof....the chamber pressures they can tolerate are such that it isn't even reasonable to worry about.

Jim I have the entire north side of the Dosewallips river flats to access...waiting for a gate key so we can launch your boat....did I previously say that the site has a really good high to mid tide boat launch plus parking? Supposed to get a letter of permission also as I had a run in several years ago with the owners to the south...I'll simply hand copies of it and tax assessor parcel maps to the deputies when they show up. You got any floating honker dekes?
