25 yd sighting in?

I sight in all my rifles at the 25 yd mark. And I usually sight them in to be 1\2" low at 25. This gives maximum point blank range for 200-300 yds. Just hold on the animal and squeeze off.
 
I'm the same, a .5" low sight in at 25 yards will normally get where i need to be with something shooting over the 3300fps mark form the muzzel.
 
I dont agree with the whole close is not got enough. How often will you get a yote to stop at 100 yrds, 200 yrds or 600 yrds for that matter. You need to sight in your gun so you can be in the kill zone at as many distances as possible. And how you choose to do it doesnt matter. close is good enough, For hunting.
 
I'll stick by my statement. "Close won't kill a coyote, gopher, or other vermin." As a matter of fact you will end up with complete misses or wounding shots. Go ahead and practice your distance shooting at close range. You're holding water in a seive. Practice at the range you intend to shoot whether it is 50yds. or 600yds.

Guys think of it this way how many of you would be comfortable with a rifle that was bore sighted only for the big hunt. Not me.
 
The 25 yard sight in is intended to get you close with fewer shots. Once you have it zeroed at 25 you back up to 100 or whatever you want it zeroed at and fine tune it. Seems simple enough to me. If you assume it is where you want it just because it will hit at 25....well, you know what they say about assumming.
 
Well they are calling for windy conditions tomorrow - dang it!!! I was going to skip the 25 yd indoor range and go to the outdoor range where they have a 100 yd range. I guess I'll have to try it on Monday after Christmas. Maybe I'll get some Christmas money and buy me shooter's bench or vise to hold the gun steady.
 
I was referring to sighting in a new rifle/scope combo at 25 first, to get it on paper. Then of course I would move it out to 100. I was just wondering if the 250 point blank would be close to actual?
 
I'm switching sides---though I've had rifles that had a good 25 yd target, stay good further out, I'm not sure I'd bet fur on it. At least not everytime or every rifle.

Went out to the range last week with a friend who has a chance to go hunting for a 450-500lb bear. Another guy he knows has seen the bear in a particular area many times. Anyway, he had to resight in his 338 because he had been switching scopes around during deer season. We had a pretty good 25yd group and at 100 yds it would have been in the kill zone on a bear, but he's been told that he'll be lucky to get within 250 yds. The 25 yd sight-in would have been worthless at 250yd, and I'm glad we took time to fine tune at 100 yds because when we went to the 200 yd range then it was where it should be.

I like the ballistic programs but I'll use the 25 yd test as a starting test, and fine tune at longer distances, especially if I'm after a game animal.

Desert_Sniper, The numbers you originally quoted should be a good start.
 
I would never use a 25yd sight in to shoot longer distances unless it had a norm target at the longer distance to start with as I mentioned above.

I use the 25yd sight in as a starting point when zeroing a new scope/rifle. Then always sight rifles dead on at 100 yds. After that a 25yd norm target is shot with that load/rifle and kept on file.

Your question: I was wondering if you can effectively sight in a rifle at 25 yds and still be on out to 100 - 150 yds?
------------------------------------------------------------
Yes you can and with out firing a shot.

If you bore sight at 25 yrds,then most rifles will shoot pretty damn good at 100 -150.
I have bore sighted many many rifes in the last several years and all at 30 yds, right from inside my house. It would be a rare except if I ever had to shoot over 3 shots to have it printing 1" high at 100. This is with the scope being 1 1/2" above the bore.

I throw up a target on the edge of my garage and with the rifle in a cradle I bore sight it from the kitchen table.

Now this of course won't work with a pump or auto, so then I would shoot the rifle to print dead center at 50yds.

This has been farily accurate for me for a long time, once you learn to bore sight your rifle the same way every time, then you be able to get your shots down to just 1 or 2 and be done with.



I agree. I bore sight bolt actions at home most of the time. I will put a bipod on the rifle and use a rear bag and center the bore on an object like a roof vent, lamp post, or other sharp object on one of the neigbors roofs down the street-(from well inside my house). Then I move the cross hairs to the best guess of where the center of bore is aiming. It will usually get me within about 5-6 inches of the center of target at 100 yards. Once your on paper, you should be able to get where you want to be in another shot or two. You can also do this at the range by centering your bore on a corner of the target and making the adjustments.

I own a boresighter with a complete set of studs, but I only use it on rifles other than bolt actions. You can get closer by bore sighting with practice. Hunters that travel far distances will practice this, along with verifing the accuracy of the scope once they get into camp.
 
What you are failing to understand is that a bullet crosses line of sight twice. It is perfectly accepable to sight a rifle in at close distances and still expect it to hit dead on at 200 yards. This all depends on of course the bullet weight and velocity as all bullets won't fly exactly the same for everyone. That is one reason why a chronograph is so important. I can sight my .270 in dead on at 50 yards, and it will be almost 1 inch high at 200. That just about leaves me perfect for a 300 yard shot. The bullet crosses line of sight at 50 yards, and then again when it hits the target at 200 yards. I sight my .22's in the same way. For example, a Winchester Dynapoint, if it leaves the muzzle at 1115 fps, will cross line of sight at 20.0 yds, and 49.6 yards. So really, if I sight dead on at 20 yards, the rifle is still sighted in at 50 yards. Things like bullet ballistic coefficients also come into play, but there are programs out there to help figure this out. Just my 2 cents worth
 
If you can afford to go hunting, you can certainly afford to properly zero your rifle. Bore sighting at 25 yards and calling it good enough for a trophy elk hunt in New Mexico? I don't think so Scooter. /ubbthreads/images/graemlins/smile.gif
 
Subject: 25 yard sight in

I think you misunderstand me. Physics is physics and what goes up must come down. That is why a 25 yards sight in does work. However, I agree that there is no substitute for shooting at real yardages, but that is not always practical. Not everyone has a 300 yards range at their disposal. What's important is understanding the bullets flight path and making the necessary adjustments. I hunt Antelope in Wyoming just about every year and I prep my .270 by sighting it in for 3.0" high at 100 yards. This put me just about right for out to 300 yards, at the velocity I load. So if this method of sighting in is acceptable then why wouldn't, (other than watching for bullet drift), a closer sight in be ok?. /ubbthreads/images/graemlins/confused1.gif
