    well hopefully these pictures have uploaded right and you can see that the 5 shot groups i shot today are in a vertical pattern (minus the two fliers that are the black holes... gotta love kids going nuts with a ak right next to you)
    i thought it was because of my check weld but i have been focusing on that like crazy but i think it might also have to do to with barrel whip, but then again its a bull barrel so i donno what do you guys think?
    thanks for the help

    If this pattern gets worse as you shoot a string, then starts again from the original POI after a few minutes to cool down, I would suspect some issue arising as the barrel heats up and starts pressing against the stock. If the pattern goes up, then goes up more, then goes up more, I'd suspect the scope loosening.

    I've got the exact rig as you, and I can shoot 5 in a row without waiting, and It won't string. Your groups look good to me, course there kinda hard to see:)

    If your shooting off a bipod, that could effect your groups, if you don't load it the same way each time.

    I think there is nothing wrong with those groups, and I think there is nothing wrong with the "kids going crazy with the AK" next to you.

    You were at a public gun range, right?

    when I see verticle strings on my targets I focus on breath control.

    Could also be your breathing and the timing of your shot.

    Do you use a rear bag or off the shoulder? Can't really see the groups well enough to make an assessment.

    FWIW, I have never shot consistent groups off a bipod. I use firm front and rear bags for best results...

    That is not what I would call vertical.

    Anyway.

    Consistent shoulder pressure is critical for consistent vertical shot placement, as is consistent pressure on the front stock into the rest, if you are holding the rifle in front of the action.

    Nothing wrong with the groups, you might have to tweak you loads to get one hole, but what you have is normal... Strings can be 2 - 7 and more I had Howa which stringed like 8" vertically...

    i was shooting of the bipod and rear sandbags.
    sorry about the bad picture but the groups were
    top: .24"
    bottom left: .25" (not including the flier)
    bottom right: .37" (not including the flier)
    also this was for load development the charges were 44.0gr 44.2 and 44.4gr of varget

    and i dont have a real problem with the kids with aks (i have one too) but when they try to bump fire and hit my target that really burns my butt

    I can guess .308... If this is Savage, then you got 1:10 twist and if you do what bullets are you using? 175 gr SMK?

    So, you are getting quarter-inch groups...and complaining? :D

    Nice job!

    Really nothing wrong with those groups. What ammo are you shooting? If handloads vertical stringing can be caused by inconsistency in powder charge, neck tension, or seating depth.

    Are all of your groups doing this or just those 3? Its hard to tell from the pic, but it looks like your extreme vertical and horizontal spread is even on those three(?) shot groups. Shoot 5-10 shot groups and you will probably see the vertical stringing go away.

    Possibly you are aiming at the last hole shot and repeating where the bullet strikes in reference to where the sight aligns?

    Vertical stringing from my experience is due to inconsistent breathing control.

    they look good to me. generally people's issue when they string rds, is that they are not having the same point of aim everytime. normally that is an issue that i see when folks are shooting iron sights. it could be breathing.

    I suggest using a square target. Adjust your scope so it shoots 1-3" high at the given distance you shoot at. Use your highest magnification. Place the upper left quadrent of your X hairs along the lower right quadrent of the square so that the scopes POA is on the bottom right corner of the target aim and fire at that bottom right corner, ignore your group. The results should tell you alot.

    That's not vertical stringing, this is vertical stringing.

    Your half MOA groups are pretty good, in my opinion.

    There's no such thing as "not including the fliers". The group is what it is.

    That being said your rifle is shooting just fine. There is nothing within your groups that would indicate a problem with vertical stringing. I'd be real happy with those results.

    No more dispersion than that, I'd figure maybe on a lack of uniformity in the setup of the rifle's weight on the bipod and against the bags. A bit of push or a bit of pull that's not quite the same as a previous shot. Add in a wee bit of "not quite right" for crosshairs on target.

    Real sure-nuff stringing like SlamFire's picture, I've found, is from the forearm pressing against the barrel. Differential heating changes the pressure and thus the vibrations. The worst offender I've had was my then-new Sako. 1" per shot stringing. I free-floated it and made it a sub-MOA critter, sometimes half-MOA.

    If that was a small deer sized animal, it is dead numerous times over.
