My question is this - what is a "bore-rider" bullet? Whats the difference compared to a regular bullet?
It is basically a banded bullet.
These are common in the dangerous game bullets especially the solids.
When the bullet is fired only the bands engrave the rifling and the bullet body rides in the
bore without engraving.
Most solids are much to hard to be engraved like the jacketed lead or soft copper bullets so
the bands are used because of minimum contact with the groves .
They are a little difficult to set up for long range but they do seam to increase velocity if fitted
I think that all of the really big guns 20 mm and up to the 16'' navy guns use this system
because of the size and weight of the projectile.
