Rebated Boat Tail Bullets – Simply Better And Here’s Why…
1) Muzzle blast dispersion (which causes inaccuracy) is reduced by at least 15% because
muzzle gas is deflected in a ring with the bullet shooting through the
clear space in the center instead of a ball of fire directly in front
of a standard boat tail bullet (caused by the laminar flow of muzzle gas
around the smooth conventional boat tail, focusing like a water hose nozzle in
front of the barrel).
(2) Barrel life is increased and bullet gas cutting is reduced by the sealing
action of the rebate. Gas pressure acting normal (90-degrees) to the surface
tends to peel a boat tail angle back from the bore. The 90-degree rebate shoulder
makes the gas press straight forward rather than giving it leverage to
vector the force down and pull the gas seal away.
The Rebated Boat Tail Advantage Over Flat bottom Bullets…
(1) The air flow over the rebated boat tail base is less turbulent than that of
the flat base design, so drag is reduced by up to 40% in sub-sonic bullets and
up to 15% in super-sonic bullets. A bullet passing through the speed of sound
will experience an increase in ballistic coefficient below the speed of sound,
to a greater degree than a flat base bullet passing through the same velocity/
time curve. RBT pistol bullets tend to strike higher on target provided recoil
and other effects do not affect the bullet’s exit
