bullet jump

Is there a reason most people seat the bullet close to the lands? Is there any problems with having quite a bit of jump to the lands? thanks

    Bullet jump is no problem as long as your gun shoots well with it.I might be kinda backwards to most load developement,but I start at the lands and go from there.I like to shoot VLDs quite a bit and usually get the best accuracy touching or into the lands.Ive also tried accubonds (180 gr) with a .005-.010 jump but in my gun they seem to shoot best hard against the lands along with the VLDs.But thats just my gun and in some hunting situations hard against or into the lands might not be a good idea.

    Screech

    This subject is very controversial so I will give
    you an opinion because every rifle is different
    in how much freebore it likes.

    The reason for seating against the land is to align
    the bullet to the rifling. A full length sized round
    lays in the bottom of the chamber with the bullet
    below the centerline of the bore.

    Neck sizing only helps alignment and brass life by
    minimizing head space.

    If you seat against the lands start with low powder
    charges and work up slowly (less than 1/2 a grain at
    a time)

    Some bullet manufactures recomend .050 clearance
    to the lands. Weatherby,s normaly have .250 to .325
    freebore.But the factory loads cannot be used in a
    rifle with little or no freebore without excessive
    pressure.

    So if you have a rifle with lots of freebore then
    try neck sizing .and if you want to load hard
    with the bullet close to the lands then start
    .020 off and work closer but watch for pressure
    signs then back off 1/2 to 1 grain on your powder
    charge.

    Take your time and be careful
