I am new to the site and really liking it! I have a Remington 700 adl 22-250. My problem is that if I sight it in at 100 yards then move back to 200 yards, it will shoot to the left. If I shoot at 300 yards, it shoots even further to the left. What do you think is causing this?? Any help would be greatly appreciated. Thanks!
 
My understanding of sighting in is to compensate for bullet drop at various distances rather than windage.

Is it possible your barrel is physically damaged? Maybe even bent?
 
Welcome to the board!

What kind of ammo are you using? Also, has the gun been in your possession since new? Has it been rebarreled at any time? Do you know the twist rate on the barrel?

Now, let's talk shooting technique. Are you shooting it from a rest or sand bags? How much wind was blowing that day and from what direction in relation to your line of fire?

This will give some basics to begin narrowing down the problem.
 
It sounds like you have a problem with parallax in your scope. Do some Google searches on parallax and you'll see what I'm talking about. It isn't that your bullets are curving. It is that your point of aim is shifting further left as your distance increases.
 
Quite certain it's a scope problem. As Doyle suggests, your bullet would be flying in a curved path, clearly impossible (left-right anyway).

He is also most likely correct that it's a parallax issue. If not parallax, it is almost certainly scope related.

Exactly what brand and model of scope do you have?
 
Thanks guys for replying, I am shooting my own reloads with 50 grain hornady v-max bullets. I bought the gun used, but it hadnt been shot much when I bought it. The throat was in excellent shape, and I have only put around 400 shots or so through it, and everything still looks good on it. I still have the scope that was on it when I bought the gun, its a Simmons Whitetail Classic.

When I first noticed the problem, I changed the rings and bases. It had the see through, so I got regular rings and bases to get the scope closer to the barrel, and I free floated the barrel thinking it might help, but nothing I have tried has worked. I will check into the scope itself to see if thats the problem. Thanks guys!
 
Wait! I just reread your OP...

You're sighting in at 100, left at 200 and more left at 300?

That's a whole different animal.

That's normal. Different powders and bullets group in different places. Completely normal. As long as you like the group size, adjust the scope and be happy.

You said "back to 200", I read it like "return to 200" as if you're accurate at 200 and left at 100 and 300. My bad. ;)
 
Simmons Whitetail Classic.

Likely source of the problem. The only Simmons I would even think about trusting is the Aetec series. Even those are marginal. I'm not exactly a scope snop, but I won't buy scopes that don't hold up.
 
I've never had that problem, so I'm having to guess.

Q: How much to the left of the point of aim at 2-00 and 300?

Q: Could it merely be wind drift? A cross wind would likely cause an inch or so of drift at 200 and maybe three or even four inches at 300.

As example with my '06: I was hitting dead on at 100 yards with the wind behind me. At 90 degrees to the "good breeze" and at 500 yards, I was holding two feet of windage in order to center the target.
 
When it first started happening I thought it might be a little bit of wind throwing it off, but I have shot that same scenario several times and it is the same exact result every time. If it is dead on at 100 yards, then it will be about 2 inches left at 200 yards, and 4-5 inches left at 300 yards. The further I go back in yardage, the further left it will group. I didnt used to have this problem, it was shooting fine one time, and the next time I shot, it was doing this. I am stumped.
 
Are you using the same power setting at all ranges? If you sight in at a lower setting and then crank it up for the longer ones, the POA may not be tracking correctly, common on lower end scopes. I always sight in at 100 with the highest scope setting. That way errors aren't magnified when the scope is cranked.
 
I'd start with the mounts.

If the scope is canted / (looking down on rifle), it would cause your symptoms.

I'll ask a stupid question...is the scope canted, either in the rings or the rifle by you when you shoot?

Not a stupid question at all. That was my first thought. 5" at 300 yards would take a noticeable cant, but it definitely could your problem.
 
Hunt4em I shoot a lot of 22-250 as well as other calibers. My present 250 is a Ruger MK II with a 20X Sightron. This rifle shoots sub 1/2"MOA at 100 yds and sub 1" at 200 yds. At 1/2" high at 100 yds. dead on it is about 2" low at 200 Yds and 1/2" to the right. Can't give you 300 yd results as our range does not have that yet. I think this is called ogive if I can explain its the rotation plus the rotation of the bullet. I am not real sure its called ogive thats what I call it.
I didn't see how far left you were shooting at 2 and 3 hundred? Have you tried any different weight bullets to see how they act?
 
Striker1 I knew ogive wasn't right. My point is a bullet rotates as its sent down range it rotates in a tight circle also. I am sure someone will be able to explain much better them me.
 
Hunt4em:

When I shot on several Marine Corps rifle teams I established my 200 yard zero from mechanical zero. Mechanical zero is when the peep sight was aligned center in it traversing slot, When I walked on to the line I set my zero and took a wind reading and I move the sight accordingly. At no time did my bullet drift unless I failed to dope the wind correctly. If I were you, I would change scopes. A rifle will only shoot as good as the sights that it wears. I'm not sure of your budget but I would look into a Leupold or a Burris.
