I just put a new scope, rings and base on my Remington 700 .270. For those of you that boresight your own rifles, how do you do it?
Should I buy a laser boresighter, or can I just look down the barrel and adjust the scope? Also, at what range(s) do you generally bore sight?
I have sighted in several scopes before. But each time I just started at a close range and worked my way out. Wanting to save a few steps and some ammo this time.
Any advice and details would be much appreciated. Thanks!

W/a rock steady rest, take the bolt out, look thru the bbl & match the cross hairs to the target @ 25yds. Fire one shot to make sure you're close, adjust as needed. Move to 100yds. & fire one shot. W/out moving the gun, move the cross hairs to that bullet hole. Should be done but need confirmation shot. Fire one more to confirm/fine tune.
Good luck!

LFD2037 nailed it. I have an arbor and a laser bore sighter because I used to mount several scopes a week. If only done occasionally then the method above works great.
Don’t roll those bloodshot eyes at me.

Good luck! This. With a modification, I mount and bore sight at home. I have sighted at objects out to 50 or so yards through the bore. (like a post and top rail on a chain link fence) then one shot, move the cross hair to the shot.....the farther you can bore sight the closer to zero you'll be.
An unethical shot is one you take, that you know you shouldn't.

Good luck! since I am now stuck in the big city for a while, I have been banished to shooting with the masses at public gun ranges. I just can't describe how many times I've seen folks shoot BOXES of ammo trying to hit a target and scratching their head after they paid to have their new scope "boresighted" at the local gun store. If I get an opportunity to help, this is the method I use as well. I go straight to the 100 yard line with a 6" black round target on a big piece of paper. Rarely takes me more than 3 shots and 5 minutes to zero a rifle scope (with good equipment.)

I do exactly what LFD said, but I use a distance of about 100-200 yards out. 25 yards is way too close, IMO. If you sight in that close, you will be off at 100, which takes more rounds. I want to bore sight and zero in as few shots as possible. If you get the center of your sight picture through the bore to the center of the cross hairs at 100-200 yards, you will be within a few inches of zero. I'm often about 2-3 inches off. If I'm at home, I'll lay prone with the rifle supported on a bipod, and look through the glass door or window, and use the neighbors chimney or roof line. If at the range, I'll use the 100 or 200 yard target to bore sight through.
Also, when looking through the rifles bore and dialing in the scope, the adjustments are backwards. To move left, you dial right. To move up, you dial down. I do this method with almost every rifle I shoot, so several times a week.

I wish I could! Damn astigmatism is a PITA when trying to be half-[censored] precise.

Looking through the reduced area of the rifle bore actually helps reduce the detrimental effect of astigmatism, just like looking through a peep-sight does. Even with my 70+ year old eyes, I can get on paper bore sighting at 100yds. With an AR type rifle, I take the upper off and bore sight that way. With a lever-action I use the "shoot at close range first" method and make sure I have a BIG target. If you are not on paper with your first shot, you can really waste a lot of expensive ammo shooting who knows where....

Unfortunately I can't see well enough so I use the Pursuit bore sighting kit (arbors from .17 to .50 and shotgun). Works fine.

Good luck! Works every time. I personally try and leave that 25yd shot about 2" low, then move to 100. Not a deal breaker though. Like others, I cannot see the target well enough through the barrel at 100 yds, much less 200.

Yep, wear bi-focals. See close okay far away is a bummer. Have to use a scope can't focus open sights to distance object, have to bob head up and down. At home set up 25 yard target bore sight then two the range.

I also do 25 yards. I can't see past that. I just setup a 30-06 this way and only had to make one windage adjustment.

I've gotten into the habit of bitching about having trouble seeing close up. I guess I've really got no reason to bellyache. Not much, anyway.
You fellas who have trouble with iron sights, I can sympathize with you...but if you've never looked through aperture sights, you really oughta give it a try. The smaller the aperture, the better.
I bore sight on a neighbor's porch light about 100 yards away. I will usually fire at least one round at 50, though, just to be sure I'll be on paper at 100. I do have one rifle that just does not tell you where it's going to hit by boresighting. I think the receiver's D&Ted a little off center. Shoots good, though---once it's zeroed.

ARs are a bit harder because you can’t remove the bolt. Sometimes I find it helpful to use a laser to get the left/right alligned.

You can if you separate the upper from the lower. I have a cleaning rod guide that I can see through and it will hold the upper/lower apart, but I've not gone to the trouble to figure out how to take advantage of that for bore sighting. It's easy enough with upper and lower separated.

Just take off the lower and take the BCG out. Done! AR is easy but not as easy as just pulling the bolt on a boltaction to me. Lever actions are the most pain to bore sight to me. I usually bore sight at 50 yards and shoot to verify before going longer. Msny cartridges that will put you very close at 100 yards.

Well you are the god of shooting as you like to spout off It can be more difficult on ars with the just the upper, as it's harder to brace. There are things you can do to help but it can be difficult for people doing it for the first time.

Now you went to far. It's not my fault when idiots get on here and give what they think is good advice. And other people are going to believe that is good advice. I can't abide that. You just gave bad advice based on your personal lack of brain power to do something, and was called out on it. My 9 year old daughter has learned to accept being called out. Evidently you missed the lesson at some point in life. Pull the back pin, split the upper from the lower, pull bolt and changing handle. Upper on a bipod or laying across a pack and bore sight down the bore like any other rifle. "Can't see through the barrel". Your quote, and it is completely wrong.
