bought this used rifle for my son put new scope on after a few shots getting it close. it will put 2 to 4 shots in 2inch group then 1 out of every 4 or 5 it will shoot 10-12 inches to the right i have cleaned it and checked everthing for tightness any ideas?
 
I've shot 3-4 Vanguards and they've all been consistently MOA or better.

Could be it doesn't like the ammo you're using. Could also be a problem with the scope.

Is the barrel heating up?
 
Sounds like the scope to me. What kind of scope and rings? What kind of ammo? As Inspector3711 says, Weatherby Vanguards are usually pretty good shooters right out of the box.
 
My Vanguard Sporter consistently groups around 1.5" or less at 100 yards with Hornady ammo. With Remington or Winchester, I get 2 to 3 inch groups. My rifle does not like them much.

To answer your question better, I have more questions for the OP?

What type of ammo are you shooting (factory or reloads)? How much time elapse between each shot (barrel getting hot)? Are the flyers consistently happening (start to finish)? How many rounds have you shot? Does the grouping point of impact change?

My first guess is your rifle does not like the ammo you are shooting. My second guess is (if the flyer is the 4th or 5th shot) the shot is being rushed.
 
Assuming the scope doesn't have bad reticles and that it is good and tight, then I suspect flinching. If the zero doesn't wander but you get a consistent BAD flyer in any given group - blame the shooter.
 
My Vanguard will shoot 1/2 MOA at 100yds with Hornady 139 grn BTSP's, It might shoot even better if someone that shoots better than me gives it a go. Check rings and bases then scope.:)
 
If 4 of 5 shots are in the same area and then the 5th shot is way off then it's the shooter.

If the group is pretty big (over 3" at 100 Yards) I'd say it's ammo.

If the first 4 shots are in a group and then the 5th and following shots are are in another grouping, then check the scope.
 
My Vanguard was less than 1 moa out of the box with factory ammo. That was with Federal blue box ammo. It doesn't like Remington at all. Then I got started handloading and it really loves the loads I have worked up for it.

I think the previous posters are giving you good advice about ammo and possible shooter errors.
 
could be the same problem i have with my 257 moa vangurad. with a clean barrel it will shoot a bit less then moa for the first 3 a bit over moa for the second three then all bets are off. By the time it gets to around 12 shots its shooting 5 inch groups. This is with a cooled barrel. Even if you put it away overnight and come back its 5 inch. Clean all the copper out and start over and its good. I sent it to weatherby and told them it was fouling bad and they were snotty about it and said there gurantee is 3 shots not 6 or 9 and i should just get busy and clean it. Good luck if you want to use there customer service dept as its about non existant.
 
If it is a fouling issue as the last poster said then there's something definitely wrong there. None of my guns lose accuracy that fast or that much from fouling. I'd be on the phone to them. If they won't fix it I guess you'll end up real good at cleaning the rifle.
 
Many folks will buy a new rifle and put a box or two of ammo through it and sell it , for whatever reason ! It's possible that your barrel isn't broken in yet . Shoot and clean every half dozen rounds or so for a couple hundred rounds and see what happens then ! I've never seen a barrel that didn't get better after proper break in ! JMHO
 
You didn't say which Vanguard it is. If it is the Vanguard Synthetic and is in the factory stock it is hollow and has plenty of flex. I have three of them and I free floated the barrels to eliminate any influence the forend may have on the barrel.

It's easy to check this with a gridded bore sighter.
1. Put the bore sighter in the bore and align the grid with the reticule. Do not hold the rifle by the forend when doing this.
2. With the scope at its highest power note the position of the reticule on the grid.
3. While looking though the scope at the grid take your other hand and push the forend in different directions.

If the reticule moved on the grid the forend is moving the barrel. You can take this one step further by carefully removing the stock, bore sighter still in place, and noting any changes in the reticule position on the grid.

Hope this helps.

You need to have another shooter try it. A repeatable error like that does't make me think it's the scope.

what scope is it by the wya
 
it is synthetic 7 mm mag bushnell 4x12x40 scope everything tight two different shooters doing the same barrel getting very hot only had about 25 rounds thru it
 
You can't let the barrel get that hot with a thin barreled sporter rifle and expect MOA results. You need at least a minute between shots for a 3-5 shot string to get optimal accuracy.

Try shooting it slowly (1 shot per minute or more). Don't let the barrel become too hot to touch when you take the next shot.

That scope should have the parallax preset at 75 yards. If you're shooting at distances greater than that, it can cause issues, when you don't use a repeatable technique.


It sounds like the issue is the rest, or the shooter(s). If you're shooting over long distances, the wind may be a factor, as well.
 
You say the rifle was used when you bought it.

That could mean anything..
It could be nearly shot out...
There could be muzzle damage, from improper cleaning.

Have you thoroughly inspected the bore, and muzzle, for any damage? Is the bore bright? Lands sharp?

If none is evident, I'd do a thorough cleaning with a good copper solvent- I like Wipe-Out- let it have a good overnight soak and patch it out the next day. Repeat until there's no more blue...
