Has anyone actually solved the flyer shot????

This weekend I was doing some load development out to 330 yds (300m).
Every three shot group had 2 close and one flyer. The flyer all went the same way 4 inches below the other two.

Google produces a million probable causes, but only one had an answer.

In my opinion it cannot have anything to do with the ammo and loading. It is impossible that 1 out of every three rounds were loaded differently.
It also has nothing to do with barrel heating up. It has nothing to do with the obvious stuff. It also has nothing to do with a 3 shot group versus a five shot or 10 shot group. One guy on a forum spoke of a 5 shot group of which one of the five was always a flyer. It is impossible that one out of every five rounds he loaded was different ie diff OAL, charge, seating depth etc etc. 

So it must be in the rifle setup. Maybe a bedding issue or torque issue???
 
The one guy that solved his problem of one flyer per group cut 2 inches off the front and recrowned. That solved his problem.

So anyone who had this problem and then solved it?

And before you ask, at this stage I do not know if it is the first, second or third shot producing the flyer.
This coming weekend I will have that answer.

I've taken the same rifle and ammo to the same range on a given day and shot very well; then taken the same rifle and ammo to the same range on a different day and shot terribly.

Whomever wrote the response above misused the word "impossible".

The greater the N, the easier it will be to answer the question. If I had to guess, I'd say you shot 2 or 3 strings of 3 and had fliers on each. Shoot 20 strings of 3 and see what happens.

And let us know.

Rancid thank you for the response.

I shot 5 groups of 3 shots each and have the same flyer in the same place. 

However, other shooters have experienced the same issue, even on a 5 shot group.

Yes, one of the million possible solutions is a statistical matter.... shoot enough rounds and the flyer will get swallowed up in the overall grouping produced. Has anyone else done this?? Shot a flyer or two in a 3 shot grouping and then shot a 20 round grouping??

And I stand by the "impossible". It is impossible to produce 5 x 3 loads and have 1 in each of those 5 loads different from the other 2 in the same manner to produce the same flyer in the 5 groupings. Or as per the other guy who shoots a string of 5 shots with the same load and 1 of each five shots produce a flyer because it was not loaded the same as the other 4.

Maybe I am wrong, therefore if anyone has had this 1 flyer on a consistent basis and then found something to fix. So that after fixing the thing (loading, runout, barrel harmonics, damaged crown, shooting 20x5 shot groups etc) the flyer went away.

Rancid, I am posting this question because I do not want to shoot 20 x5 shot groupings. I was hoping someone else  has done this and has the answer.

I really don't think it can be narrowed down to one thing that would be the same across the board.  One guy may find the solution for his 1 rifle, but his next rifle will likely be something completely different. 

In a case I had with one rifle years back, it would have a flyer every 6th round.  I had it skim bedded and with that rifle, it fixed the issue.

Supertool I find your problem more plausible. In other words the rifle had an issue and not the rounds.

I maintain that you cannot load every 6th round different, or somehow pick out of the box with 50 rounds in it 5 good ones and the 6th a bad one every time. And then on the next firing again 5 good and 1 different.

So, to be clear: a 3-shot group results in 1 flier, and a 5-shot group results in 1 flier? Does a 10-shot group result in a few fliers?

Are you shooting a string complete or looking for bullet holes after every shot?

I also should have stated at 6 rounds it would start having the flyers.  If I kept it hot they would continue at or very near the new POI.  I have always liked shooting 10 shot groups just to test myself and found that issue with that rifle.

I shot 5 strings of 3 shots each at 330 yds. At that distance I cannot see the bullet holes. So I do not know in what sequence they are.
Two bullets in each string would be close to one another and close to the aim point. (less then MOA stuff). In each separate group would be 1 flyer about 4 inches low and slightly to the right. 

The five shot group I am talking about is not me. It is from someone who posted on a seperate forum where he talks of a 5 shot group with one of the five being a flier. He was also looking for an answer. He shoots in competitions and the flyer is always there.

I picked this up whilst Googling my problem. The answers are stock items: 
Concentricity issues, wrong seating depth, to much of this to little of this, pulling the shot, poor concentration, inconsistent powder charge .... I can go on and on.
BUT everyone is guessing, no one is saying: I had that flyer problem too, and this is how I fixed it.

How can you load 4 good ones and one bad one every time you put 5 rounds in the mag?

So if it is because 3 rounds x 5 is not a high enough number to prove it is just a poor overall grouping, has someone shot enough bullets to get pass the flyer phenomena to prove the numbers game?

I have not shot more than 3 bullets at a time.
However the 5 similar groupings of 3 shots each is enough to convince me I have some issue.
I just do not know what.
I also believe it is not the rounds due to the consistency of 2 good 1 flyer, two good, 1 flyer..... It is also not the scope mounts.

How big is the barrel?  I have a browning 300 wsm with a pencil type barrel.  It will shoot 3 shots right near moa @100.  But 4 and 5 always opens up a bit, 1.5 to 2 moa @100.  I have never took the time to properly bed the rifle.  It was bedding by browning, but it looks pretty crappy to me.  Looks almost like a hot glue bedding job to me.  Just bedded at the action bolt points.  I dare bet if I bedded the whole action and down the barrel a couple inches it would help some more. 

But anyway, I have always attributed it to heat and that barrels gets pretty dang hot at 3 rounds.  4 and 5 it is to hot to touch.  But I let it cool down and 3 shots are again good.  4 and 5 it opens back up.  It is very consistant.

My advice: shoot longer string. I like 10-shot strings, they really show where I fall down and what the gun/ammo can do.

And maybe try good factory ammo and get rid of that one variable.

In the end, I think you will find that:
1. More shooting will result in fewer fliers.
2. Most shooters that post extremely tight groups have cherry-picked from many groups.
3. A 1/2MOA group does not a 1/2MOA rifle make.
4. When you have 20 or 30 groups and still see the pattern, investigate further. Till then, shoot, and have fun.

For me, fliers are a part of shooting, they are the result of any number of factors, from gun to ammo to shooter to environment.

Respect is something you earn.
Equality is something you whine about not being given.

Wouter, I would agree it is likely not the rounds.  With good loading techniques/consistencies at those short distances I doubt loading variations could be making that much difference and least those consistent of differences.  And I think you know what you are doing in that area. 

We don't really know anything about said rifle, but flyers from my experience and understanding that are happening consistently are typically heat related.  Meaning as that barrel heats up things move and pressure is changed.  That barrel expanding because of the heat will push on the action and stock and make things change.  A good bedding job with consistent torque settings is always a good place to start.

Its as frustrating as trying to correct cold bore flyers. As always you need to eliminate as many variables as possible. One thing that tells on load issues is velocity. Any time there are flyer issues you need to watch velocity. A 30fps variable can cause flyers for several reasons (time of flight effects, harmonics ect). I have had results with factory rifles that had a loaded fore end by removing the load bump and free floating the barrel. Others had to be bedded or rebedded. I have watched some that I rebidded still have flyers just in a different place on the target. Another thing that can drive you nuts is the distance you are shooting. I don't put much stock in true accuracy at 100yds. Unless it is a set up that 100yds is the objective. Most of my rifles don't tighten up until 200yds. But that is one of my goals because I am focused on long range (1000yds +)accuracy. I have found better consistency by not having any bedding past the barrel lug. That can be one way of adjusting harmonics if nothing else seams to help. But if you start out with bedding past the lug you really don't know if harmonics is an issue. This is a topic I am constantly watching for anything I haven't tried. Another major issue is the shooter. We all have habits we are not aware of until we make effort to identify problems. I have found myself trying so hard "not'" to have a flyer I blow the group anyway. A lock down rest that has a recoil dampener on the butt "that does not allow shift" is needed to eliminate shooter form errors. Some rifles shoot best in a tight lock and others do best with just enough to keep it from jumping off the rest. That is another variable to be dealt with. For me 3 shot groups are for quick test make sure it is ready for an event. 5 shot groups tell more about what your rifle is doing in the stock or chassis. And help you know when you are being consistent in you shooting form.
Good info thread!! keep it hot!!

Something I forgot to mention before is trigger consistency. I have been a huge fan of Timney and still highly recommend Timney. But I have noticed the newer ones I have used are inconsistent in their break. Some as much as 8oz. Granted a clean crisp break will still give good consistent groups, the break weight variable needs to be watched. I can't stand any Remington trigger because there are so many issues to deal with. I know a few smiths that rebuild them with good results but I am not one of them. But to make the point, any trigger that breaks consistent is a major component in the elimination of flyers.

Thank you for all the info. I will try a few new tricks this week end and keep you informed.
As Sgt D is saying:
Yes I am shooting 3 round groups for quick basic info. I am well aware that this is basic info and that 5 or 10 shots are far more informative.

IF I see flyers, I've found that changing guns (and calibers) usually fixes the problem... no issue.

Just kidding.  Interesting commentary, looking forward to your solution.

I have also been advised that if you can find out which shot in the string is the flyer, just skip that one and move onto the next shot!

I’ve found that if I fire all my groups at 10 yards, curiously the flyers seem to disappear.
