The accuracy standards that were set by Tar-Hunt in 1991 are still the standards by
which all other slug guns are judged today.
In 1989 Tar-Hunt set out to make a big bore rifle to shoot sabot ammunition. We didn't
want to make just another shotgun with a rifled barrel on it.
We searched the industry both past and present, at which point we found that nothing
of the quality that we envisioned had ever been manufactured before. The precision
and quality of the parts that were available was totally unacceptable. They did not
compliment the quality nor the craftsmanship of the bolt action slug guns that we
wanted to manufacture.
The decision was then made to go ahead with this new big bore slug rifle even though
it meant having to do a complete redesign. We decided that if Tar-Hunt was going to proceed
with a totally new concept, we would make use of our years of experience in both building
and shooting bench rest rifles, and build the ultimate slug gun.
Since nothing of this quality or accuracy level had ever been done before, we knew we
would have to research both the entry level and advanced levels of design. We discovered
that once the shotgun thinking was taken out of the equation we had to
establish the following:
- Industry standards were 1-34 twist rate used for Foster style lead slugs. This
means that the slug rotates one full rotation every 34 inches. Research showed
us that this was not the proper twist rate for sabot ammunition. After one
full year of testing numerous twist rates including going as far as trying a
gain twist barrel which means the slug would start rotating at 1 turn every
100 inches (1-100) and ended up at a rate of 1 turn every 28 inches (1-28).
After all of the testing, we established that a 1-28 was the proper twist rate
for 90% of all the sabot ammunition used in the 12 gauge bore size. The
following year the rest of the industry followed our lead.
- The industry standard at the time was to use porting as a muzzle break
system for recoil reduction (i.e. Trap and skeet shotguns). Research and
development showed us that a 360 degree muzzle break was more efficient at
reducing recoil and it enchanced the accuracy by creating better
separation of the sabots.
- Tar-Hunt was the first production slug gun with a heavy wall barrel as
standard, reducing barrel windup (twisting).
- Tar-Hunt was the first to use chamber designs and tolerance more suitable
for use with rifled barrels and rifle-like accuracy, and not the big as you
can make them chambers used in smooth bore barrels.
- Proper degree of angle for the muzzle end of the barrel crown for use with
plastic bullet parts and shotgun type powders.
- Research and development was done to establish the proper stock configuration
and stiffness. Why? Because of the severity of recoil, torque generated
and the vertical bounce on the for end caused by shooting high velocity heavy
recoil slugs. The decision was made to use McMillian fiberglass stocks
or a wood laminated style.
- Standardize the use of a rifle style trigger as well as being able to use
after-market custom adjustable triggers without any modifications to the
slug gun.
- Tar-Hunt was the first to use rifle firing pin lock times on a slug gun
(Quickness of the firing pin fall until it hits the primer).
- Quality rifle type action made from solid bar stock, not a receiver made
from a piece of tubing.
- And action able to mount 90% of available optics using commonly available
mounts without gun smithing.
- Quality Finishes: Using older style high temperature bluing
process instead of the new low temperature blacking process. Custom
finishes available by Robar of Phenix Arizona.
- Tar-Hunt standardizes glass bedding of the action and a free-floating barrel.
This is necessary because of the type of heavy recoil and the inclement weather
likely to be encountered during most deer seasons.
