bullet jump

[screech]

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.

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
