    you can get them to shoot great out to about 250 yards... they're going to spin too fast for good long range accuracy in a 1:9 .243 win barrel.

    I'm still working on a load for these. The best load I've found so far is with 47.4 gr of H4350, CCI200 primers, Win brass, loaded .040 off the lands. Three shot groups averaged .563 inches at 100 yards. Velocity was 3500 fps through a Savage model 10 with a 22 inch barrel. I have not shot them past 100 yards yet.

    I've also had very good luck with the Sierra 60gr Varminter, 46.5 gr of H4350, CCI200 primer, Win brass, loaded .020 off the lands. Three shot groups averaged .600 inches at 100 yards with an average velocity of 3500 fps.

    your best load with the 3031 is going to be around 40 grains... so that ought to do it.

    give these bullets plenty of seating depth... most folks try to make them reach the lands and they end up having very inconsistent neck tension. OAL should be around 2.595 max inches (bullet tip to case head).

    looks like you're well under that number... I think Hornady's OAL on their v-max 58 grain load is around 2.595"...

    good luck. :)

    My COL was 2.698 and neck tension seems fine. I do anneal the cases every time though.

    NO this is incorrect. . out of a good barrel these will shoot awesome even with an 8 twist. go to 6mmbr ; and the .243 or 6mmbr data. the accuracy load from nosler is with H414. good place to start. otherwise varget and I4064.

    I'm going to call you on that...

    Begin by explaining why barrels are made in different twists...

    (Why not just have a 7 twist for everything?)...

    I'll post an article later to explain the reasons for this, but for now, we can just discuss it. :)

    Remember, we're talking about long range accuracy... I have not said they won't shoot okay at shorter ranges (to about 250 yards).

    H414 with a mag primer in front of the 55 grain Nosler has worked great in 4 243s for me. They seam to do a little better in the 10 twist but have done alright in an 8 twist. Doesnt matter that I cannot find the lands but it does seam to matter on COL.....The current 243 likes the 55 seated to 2.633. By far the best video produceing round useing prairie dogs as a target=Red-Mist!!
    Have found the 55s to shoot ½moa + or - @ 100 yards but its tuff to keep them MOA @ 400 yards. Not really a problem as one 243 is set up for 55s inside of 350 yards and another 243 is set up for 105s past 350-400 yards.

    Mach... here's the reason they're not doing so well at 400 yards... I made this with MS paint... so overlook the crudeness. :eek:

    [​IMG]

    Lots of folks would say that the bullet does not change it's orientation to fly tip first on the downward part of the trajectory curve... however, if that was the case, you'd see oblong holes in the target at extreme range, and alas, you don't... the holes are nice and round just like at 100 yards. So the bullet *must* alter it's axis to fly tip first.

    Pistol bullets, or even deck gun bullets from large ships are about as big around as they are long, so they don't really turn into the wind like long range rifle bullets do. You can hold a paper airplane in front of a running fan and see that unless it turns nose first into the wind, it will easily be pushed aside. Not a perfect analogy, but this is basically what a bullet flying into the wind is going to try to do; it'll try to fly tip first.

    Over stabilized bullets resist this needed axial change, just like a spinning gyro-scope resists having it's axis changed.

    It might be supposed that 55 grain bullets won't group at 400 yards due to wind, but that's not the case. 22 caliber 55 grain bullets, if not over-spun, will group at extreme range.

    I'll bet you if you push 5 of those into the case until the total OAL is 2.595" (bullet tip to case head)... those 5 will shoot tighter than any of the others...

    It's worth a try. :)
