I took the Model 700 out of its box, wiped it down
to get the "new" off and said aloud, "Wow! This is a pretty
rifle". I blame this comment on my wife. She watches a couple of TV
shows with me that I like, so I have to watch a couple of shows
she likes. A couple of weeks of watching her "Grey's Anatomy"
and "Private Practice", on what I like to refer to as estrogen
night and I start having salads for lunch. Good Lord!
Firearms produced by a couple of the leading
manufacturers today have more than a little aesthetic appeal. I
recently saw this in the fit, finish and mechanical design of Ruger's SP
101 327 Federal Magnum revolver and clearly this is the case
with this Remington. The VS SF II has just the right touches
from action's bright
stainless finish to the cleanly jeweled bolt. The barrel is spin polished and the longitudinal flutes
and shallow angle target crown are black powder coated. Bottom
hardware is aluminum, textures and strategically polished. The
ergonomically contoured H-S Precision varmint style stock is
finished in matte black with green webbing. The gun is mechanical art.
I took out a few of my Model 700's that represented a
progression of Remington firearms that began with an early 7mm
Magnum M700 BDL and the evolution of the M700's design was
incredible. Some products get more cheaply made each year;
nuance parts and assemblies are cost reduced out, inferior
materials replace wood and steel. Not the case here. The M700's
being sold today are a much better made firearm; materials,
workmanship and design.
416 stainless steel is used for both
barrel and action. The action is machined from cylindrical
stock, not cast. The 26" barrel
terminates at an 0.820" outside diameter at the muzzle
which is capped with a dished crown. The barrel is
strengthened, aided in heat dissipation and kept light in weight
with the application of six 19 1/4" flutes. The flutes
diminish in depth for the last six inches as they get closer to
the chamber end of the barrel and chamber pressure.
Rifling is hammer forged, twist is 1:14" 6 groove right.
Remington's 40X has cut or "button" rifling, which would suggest
cut rifling is more desirable for dimensional control and
accuracy, however, so do the Model 504, Model 597 rim fire guns
and the economy bent Model 710 center fire rifles. I'd speculate
that economy of scale and production volume dictates the rifling
methodology and cut rifling is more cost effective on short
production runs. Based on prior experience with various hammer
forged barrels, I do not believe this is a production concession
that results in reduced accuracy.
The
.220 Swift VS SF II employs a standard length action. Left -
comparison of the .220 Swift bolt to a .300 Ultra Mag bolt. All
Model 700 variants have opposed twin lugs with a recessed bolt
face that is part of the Remington three rings of steel full
enclosed cartridge system; bolt face, chamber walls and receiver
ring.
The M 700 is of push feed design, a cartridge
is retained in the magazine and then stripped out of the
magazine and pushed without being constrained by the bolt into
the rifle's chamber. In controlled round feed systems the case
rim slips under an extractor claw and held in place in the bolt
face as it is chambered. I've never has a failure to feed with
either system, but then it has only been fifty years and I don't
want to jump to conclusions. Might just be my impression,
but I believe the push feed type action is much smoother in
actuation and perhaps a little easier to operate under stressful
conditions.
Why do these established descriptions always
make their way into publication? Because, there are lots of
experienced firearm enthusiasts who are aware of this
information, but everyday new enthusiasts join us. Information
needs to serve a broad audience with varying levels of
experience. Hey, if people can build a whole cable network out
of images of shooting whitetail deer from a tree stand I think
redundancy is a minor transgression.

The "inside the guard floor plate" release (1)
is out of the way, but handy when it is time to empty the
magazine at the end of the day. The bolt release (2) is also
easy to get at, but not easy to inadvertently get tangled up in.
(3) A nice evolution to the X-Mark Pro trigger.
The original introduction of the X-Mark Pro
provided a new enhanced operation trigger for Remington. It was
tight, crisp and smooth. An excellent trigger. For 2009, the
X-Mark Pro became owner adjustable for pull, using a 1/16" hex
head wrench that is supplied with the rifle. The trigger comes from the factory set at a nominal
pull of 3 1/2 lbs and has an adjustment range of 2 lbs.
Instructions and precautions are noted in the gun's manual, but
making adjustments is very simple.
The
safety is a two position on and off affair which is a welcome
ease of use feature. I always thought three position safeties
were for the indecisive and added unnecessary complexity to a
gun's mechanical design. Something nice about
the Remington manual. It actually makes reference to reloaders
and some general precautions that should be observed. If you've ever been given the "We do not condone
using reloaded ammunition in our firearms so go away" speech
by some firearm companies, you'll realize it's unique to find
a company that tries to function in the same universe as its
customers.

One of the ways to tell a quality
firearm from a less than exciting firearm is to pull the action and
bottom metal pieces. If the gun looks as good inside as it does
from the outside, and the outside is very solid, you're in good
shape. The VS SF II has a refined appearance where ever you look. Everything is
made out of metal including the magazine follower and the
magazine box. Again, lower metal parts are cast aluminum for
light weight, everything up top is steel. The barrel recoil lug is well
placed and well supported within the stock. The two hex head
graded bolt fasteners are a nice touch and an end to screw
driver sliced finishes.
Quite a nifty
stock...

The H-S Precision made composite stock for the
.220 Swift weighs 2 lbs 6 oz, which is pretty impressive as it's
dimensionally quite beefy and it has an integral aluminum bedding block. It is the H-S Pro style with their tact contoured
forearm and palm swells. Remington lists the construction of the
stock as "...composite stock reinforced with aramid fibers." The aramid fiber description is shorthand for aromatic polyamide
fibers which are used in the production of fire and high heat
resistant material and in advanced forms of body armor. In this
application, aramid fibers add a tremendous amount of strength
to the composite material along the direction of the fiber. The
result is a highly resilient stock that is very carefully shaped
for maximum control while shooting over extended ranges for
extended periods of time.

The
VS SF II has two front tactical-style swivel
studs. The one nearest to the trigger guard is for short range
shooting. The one farthest from the trigger guard is for long
range shooting...really. No, not really, The near
stud is for a sling, the front stud is for mounting a bipod or
possibly an iPod. More importantly, my VS
SF II swivel studs are blued while my Sendero SF II studs are stainless
and I don't know why. A mystery to solve.
The .220 Swift, in the scheme of things...

A number of cartridges see varmint use around
here. They are left to right, our
.17-357 RG, the .222 Remington, the .223 Remington, the
newly added .220 Swift. The .243 Winchester appears in frame for
cartridge size comparison only. The .17 and series of .224"
cartridges each fit a different niche, each represents a
significant increment upward in power and reach.
The .220 Swift is an incredibly flat shooting fps burner. With
us since 1935, it was originally intended for long, long range
varmint hunting with a 500 yard capability for
shots at Wiley Coyote. The original factory load was a 48 grain
soft point at 4,110 fps*.
Today, the industry's treatment of this
venerable cartridge is split. Half of the bullet manufacturers'
reloading manuals seem to perpetuate the old
stories of the 1930's and 40's when barrel steel was less than
exciting and the only powder speeds available were fast and
really fast. It was a time when barrel life was expressed in
three digit round counts and rebarreling was almost a national
pastime. The other half of the bullet makers have embraced their
inner Swift, acknowledged the cartridge as a premier varmint
cartridge and an effective antelope and deer killer. In looking
at the bullets available from these various companies, I would say their
respective positions on the Swift depend upon how much R&D effort went into developing
50 - 60 grain 0.224" products that could hold up to the .220
Swift's velocity.
Rifle manufacturers have, for the most part,
favored the .22-250 Remington over the .220 Swift. Remington has
made a serious commitment to both cartridges to the extent that
both are chambered in several varmint rifle configurations, like
the VS FS II, as well as Remington's 40-X Custom Shop tactical
and range rifles. Ammunition manufacturers are not in short
supply with six major brands actively producing thirteen
different loads including one for Remington's EtronX
electrically discharged rifle.
Ah yes, a
4,300 fps conundrum...
Pictured, right, with the smaller .223
Remington, you'd think the larger cartridge would handle the
heaviest bullets with greater ease, but not so. With
a typical 14" twist rate, the Swift will stabilize, and shoot
accurately, most lead core flat base bullets up to 60 grains,
(fourth from the left). The remaining five bullets to the right are intended
for the .223 Remington where twist rates fall between 7" and
10".
For the most part, non-military/security applications for the heavy
bullets are for competitive target shooting. Here, softball
lobbing trajectories on the way to fixed target distances are
not a problem and a heavy bullet's contribution to wind drift
reduction is significant in determining the outcome of a match.
The .220 Swift's forte is where precise distances to targets may
not be known and may be, in fact, continually changing. In these
circumstances, the Swift's high velocity and extremely flat
shooting characteristics are of consequence. So the question may
be raised "Why not increase the .220 Swift's twist rate from 14"
to 9" or even 8", then break out the heavy bullets and
the light bullets and get the best of
both worlds?" Glad you asked, I've been wondering the same
thing myself. It seems the .220 Swift cartridge's best quality,
velocity, is also it's Achilles Heel, one that prevents it from
utilizing a twist rate similar to the .223 Remington across a
full array of available .224" bullet weights.
Putting spin on
the issue...
I will advance the notion that stating a rate
of twist is only a simple way to communicate the rotational
speed that is required to stabilize a bullet. Twist rates are an
expression of a means to an end. I say this only because a
static twist rate does not result in a constant rotational speed
as rotational speed will vary with the velocity of the bullet. A
bullet's rate of rotation has to be fast enough to provide the gyroscopic inertia
necessary to stabilize a bullet so that its longitudinal axis tracks true
to its intended path and is devoid of yaw.
Spin a bullet too fast and there are consequences. Tight
twist rates increase bore friction and therefore accelerate barrel wear. In
a publicly aired failure analysis conducted by Berger Bullets,
that company cited thin jackets and elevated bore friction as a source of
lead core melting temperatures
that resulted in bullet failure.
Bullet rotational speeds can be increased through
tighter twist rates to the point radial
forces can exceed the strength of a bullet and cause it to fragment in
flight prior to contact with a target.
I used two common weight bullets to construct
the model below, both firearms with an 8" twist and the .220
Swift additionally listed with a 14" twist to see how they all
stand in regard to rotational speed.

Bullet stabilization in a
sporting rifle generally occurs between 200,000 RPM and
250,000 RPM. Allowances for over rotation of light bullets
for a given caliber as a compromise to fixed twist rates
raise the ceiling to approximately 300,000 RPM. Three
mainstream bullet manufacturers suggested that, while the
actual number is influenced by jacket thickness and core
type, bullet rotation should generally be kept below 300,000
RPM to avoid bullet failure. The .223 Remington with an 8"
twist could basically cover all bullet lengths consistent
with bullet weights from 52 grains to 75 grains. With an 8"
twist, the .220 Swift would marginally manage the 75 grain
bullet and be way over maximum rotation with a 52 grain
bullet which would probably result in bullet failure. With a
14" twist rate the Swift can stabilize the 52 grain bullet,
but not spin the 75 grain bullet fast enough to provide
stability. My conclusion was that factory 14" twists are
suitable to most .220 Swift applications and running a
tighter twist could in a rare case result in bullet failure,
however, it would seem a 10" twist would be a better
compromise, but I am sure there is more to the issue. Please
see distracted student, poor academic references in the
first paragraph.
Conclusion

If you can't tell, I can comfortably say I am
very pleased with Remington's VS SF II and I am really looking forward to
wringing out the Swift cartridge. I picked up a very nice scope for the occasion,
lots of powder and bullets and I am looking forward to the firearm exploration and education.
These are the types of projects I really enjoy and I got to work
my wish list down to four. I
will be back soon to report how the bullets flew out of the barrel
rather than my calculator.
