Thumper vs. 7.62 PBS?
These ammunition types are actually intended to comprise a complete
The 7.62 Thumper is reasonably priced, and allows the shooter
to hone his skills with subsonic rifle ammunition. When it comes
time to hunt, out comes the 7.62 PBS. The PBS offers greatly enhanced
terminal ballistics and an exterior ballistic path either identical
to, or very close to (depending on the platform) the less expensive
It’s true that the PBS patented ammunition is not cheap.
This is because it utilizes a pure copper jacket as opposed to
the gilding metal (copper/zinc alloy) used in most projectile jackets
today. The commonly used alloy is actually "tougher" and
allows for low-cost production with high-speed impact presses.
The pure copper is softer, and would not hold up to this treatment.
There is no way to automate the process any further than we already
have, so the PBS a very complicated and costly projectile to produce.
The difference in price is justified by significantly better terminal performance. The
pure copper jacket contributes to the fact that the PBS will expand
reliably at subsonic velocities. If the
user needs terminal performance unlike any other subsonic rifle
round on the planet, the PBS is the obvious and best answer. It
was not designed for casual plinking.
