Bullet goes up? when I sight this in.


Registered Users do not see the above ad.


Hey guys. I just bought new, a Winchester .300 win mag. I put good mounts and rings on it and a Redfield scope. When I sight it in, at 25yards I aim 2" high and hits bullseye, and at 100yards I aim 2" low and hit bullseye. It seems that the boolite is moving up. I'm pretty sure that's not normal plus I've read that if bullseye at 25yards, it's should only need 3-4" of adjustment. If I sight it centre at 25yards, it's 6" high at 100yards. Am I doing something wrong? Should I just learn how this particular rifle likes to shoot and except it? The gun store doesn't except returns.

Not sure what a "boolite" is, but suspect a bullet.

If you sight in dead center at 25 yds you'll normally impact something like 2" - 3" high at 100 yds. That is, providing your centerline of scope is approx. 1 1/4" to 1 1/2" above centerline of bore. Extra high scope mounting will jillflirt the normal sighting in procedure and require sighting in at whatever point blank range is desired and learing to compensate for variances nearer and farther than the PBR.

They aren't high mount. A boolite is (in the reloading community anyway) the projectile of a bullet. So if I sight in at 25yards and it's 6" high at 100yards, I need to go to a gunsmith?

My guess is the rifle and scope is okay. I'd just zero it in at 200 yards. Should be a little high at 100 and you need to learn what it does at the closer ranges.

Boolite..... never heard of that before and I'm not a beginner in reloading. Of course as my signature says I'm still learnin'. I was wondering if it was a light ghost.

This is my first scoped rifle. Thank you for assuring me it's in working order. It's very consistent; within 2". Boo... lite. lol. That's funny, I never thought of that.

No, you don't need to go to a gunsmith. You get it on paper at 25 and adjust at 100, as needed, and check at longer ranges to be sure. The point of impact at 25 yards is pretty meaningless, unless you are shooting in a target discipline that engages at that range.

You can call it a boolet or a bullet or a boolite or a case head or whatever you want.... but the more specific you are, the better folks can advise. Welcome and I hope you stick around and learn a few things.....

You can't sight in high at 25 yards and expect to hit anywhere near bulls on 100 yard target. Your scope is a certain height above the barrel and the bullet it having to go up to the point you are aiming at 25 yards. It's still going up when it gets to 100 yards, well above center bullseye. The higher the scope is mounted the higher you are going to hit at 100 yards.

If you sight it in 1" - 1 1/4" below the bull at 25 yards, you should be close at 100 yds.

You can sight it in around 60 yards and it will be close at 200 yards. Or you can sight it in about 1 3/4" high at 100 and be close at 200.

A 300 Mag is your first scoped rifle? Now you're trying to squeeze of shots from a steady rest, In that case, I'm sure you wouldn't be having a little flinch in there.

As mentioned, sight in the distance you want to shoot. Don't sight in up close and expect to be zero'd at a distance

For that size rifle, it's common to sight in on the 3" arc, which means for that one, you would sight in around 250 - 260 yards

Yes, this is my first scoped rifle. I've been shooting iron sites for quite a while. I understand what you guys are saying about the scope being higher than the barrel. I'm a pretty steady shot with iron sites at 100yards. Plus the shots I've taken with this so far have been dead on left to right. My range is only 100yards. So I'll zero in for 100yards and then find a place in the bush to zero it at 150 or 200 later.
Is it not strange that there is six inches of vertical difference between 25 and 100yards?

Zero 2" high at 100 yards. You will be very close to zero at 200 yards, and this is very useable for hunting.

There isn't 6" of vertical between 25 and 100 yards. I guarantee it.....

From all the Web searches I've done, I understand that there's not 6" difference 25 to 100. I also know that most problems are User Error. I maybe wrong but out of 5 shots, they were constantly 6" high at 100yards. That's what gave me worry. My initial thought was that the barrel was slightly bent up.

I have it set right now to 2" above centre at 100yards. I look forward to trying it out at 200yards.

Thank you. I've been taking three shots and then letting the barrel cool. I mostly shoot .303's. I think I will know a lot more about this once I've tested it at 200yards. As it's set up now, there's a 4" difference. 2" under at 25yards and 2" over at 100yards. I might have made a mistake when first experiencing the 6" difference. It sure did seem though, that when I sight it in to zero at 25yards it's 6" high at 100yards. I keep mentioning this because this seems to be my issue. Most of the responses on this thread have simply been denial of there being a problem.

It' seems to me that so far, I've said "an elephant is in down town Vancouver", and the response I've been getting is not how to deal with it, but "elephants aren't in Vancouver".

I will take it and sight it in at 25yards again, just to make sure it's doing what I insist it is. I'm open to being wrong. But first I'd like to see what it's shooting at 200yards. If it's bang on at 200, then for sure there's nothing to worry about. As for the shorter ranges; I won't be hunting anything that close anyway.

Has anyone had an issue like this? Or can think of what may cause it? The scope mounts are Leupold and a standard size. The tall mount is at the back and short at the front... just in case anyone was wondering.

Once you have it on paper, there's no reason to ever shoot it at 25 yards again. I just wouldn't worry about it. For one thing, most scopes have bad parallax at 25 yards and using them at that distance will just give you eyestrain.

I'm not sure why ya'll don't think it can be 6" high at 100 yards when zero'd at 25 yards, I think that's very likely.
As mentioned though, zero at 100 or 2" high at 100 and don't worry about it. If it's grouping ok at 100, there's nothing wrong.
A couple of things you have to remember with a scoped rifle, point of impact is going to change a lot more than you are used to with open sights. At 60 yards (zero'd 2" high at 100) you will be just about dead center and will be low closer than 60 and various amounts of high beyound 60, out to 200 where you will be at approx zero again.

I would start at 50yds and work out from there. I shoot a 30/06 and I'm 1.8 high at 100yds and **** near zero at 200 and around 1.5 ish low at 300. I've been shooting with this rifle for almost a year now and have not had to re adjust. And it's been mostly field work not bench shooting. I've stretched it out to 300 a couple times and had no problem hitting what I put in the cross. Good luck and keep us posted

~ Double check that you have the correct mounts. (Savage has two receiver styles and people frequently buy the wrong style.)
~ Boresight at 100yds.

After sighting-in you should have a fair amount of adjustment remaining in the scope.

What type rifle is it? Are you using Leupold standard base & rings? Most of those type systems do not have two different height rings, but some have two different height bases. Ruger M77s however do have two different height rings in their integral system.

Best of luck next time at the range!

Mr Clemens, that is one flat shooting -06 if you are right on at 200 yards and only 1.5 low at 300. Might want to recheck that.

I've never shot paper at 300 I'm going by the wood chucks I've shot. I put it on there nose and the hole is about mid chest. I don't shoot a lot of paper. But I know for a fact im zero at 200. All I was gettin at was that he should start a 50yds and work out. When I zero a gun I shoot from rest with bags or a bi-pod. And it's always worked well and usually takes only 5-8 rounds. I don't bust out the ruler it's either on or it ain't.

Monty you are correct I found my last paper and I was about 9inch low at 300
Sory for the incorrect info. Once I start loading my own ill be shooting more paper, and keep better records. But like I said I usually hit the range once a year. The rest is field shooting.
