Here at
Bartlein Barrels, we have the capability to produce rifling twist
rates in virtually any combination. Some will call this Gain
Twist, Progressive Twist, Incremental Twist, etc....for now we will
call it Transitional Rifling or T Style Rifling.
For
instance, we can do a .338 barrel starting from a 1-14 twist at the
breech and end up at a 1-7 twist at the muzzle, regardless of barrel
length. The rifling twist can uniformly increase throughout the
entire length of the barrel. This can be used for bullets with
driving bands on them.
For a .22
rimfire shooter or a cast lead bullet shooter, we can increase the
twist very slowly. As an example, from 1-16.25 at the breech
and end with 1-16 at the muzzle, on any length of barrel being made.
The rifling machine will automatically
calculate out the twist rate over any given length of the barrel.
We can
rifle any barrel like the above examples or we can even do it
completely custom where we manually enter in what the customer wants
for twist per any given dimension/length of barrel. As an example,
we can start rifling a barrel and the twist only go .010 for the
first 3 inches and for the next 3 inches we can have it increase by
another .015 per inch.
In short,
we can custom program any twist of rifling into any rifle barrel we
make.
