T he recently
introduced CCI Velocitor is now out among the distributors calculated to stir
much of the same kind of excitement as the CCI Stinger of a couple of decades
ago.
While boasting 30 percent increased
energy, the new round makes a significant departure from early hypervelocity
developments in that the bullet weight is the same as that of the traditional
Long Rifle solid- three grains heavier than the 37 gr. Hollow Point and heavier
by far than the Stinger and other hyper-V rounds. The possibilities in enhanced
down range performance -not to mention consistency among the internal ballistics
are obvious.
We set out to see if these
advantages are in fact, present.
I picked out three known performers
for the exercise. I would use my Remington 521 Target for the rifle-end and
with it and come up with some reliable input for the ballistic table. I set up my
Pro-Tach Chronograph first at about 7 feet and then again at 50 yards, obtaining
five-round average velocities at each range and extrapolating a useable
Ballistic Coefficient from the result. This turns up a BC of .105 plus or minus
whatever error creeps in. It is good enough for government work.
I also chronographed the load in my
6 Barrel Smith 617,
and my 6.5 Ruger Bisley.
In accord with my usual drill, I
fired all three into a 6 bullseye 100-yard rifle target at 50 yards. This was
done while clocking the loads - one at a time setting the respective arm down
after each shot to record. It was also done sitting on the ground with no
support other than my bent knees. It is gratifying to note and predictive of how
this thing would come out, that all of the rounds from all three guns were
inside the 6 black center. All hit to the existing sight setting of the
respective guns and each gun grouped a bit under 3.
The 521 T laid in a velocity off
the muzzle of 1411 fps which is well above the advertised performance of the
High Speed Long Rifle - generally given as 1255 fps or thereabout. This is a
generous estimate as recently I clocked some CCI Mini-Mag Hollow points from
another rifle at more like 1150 fps. At 50 yards, the average velocity came to
1187 fps. This is a close match for the 7 foot velocity of the round from the
two handguns and is the basis for my ballistic coefficient.
Compared to the generic Long Rifle
performance, the Velocitor Tabulates like this:
Trajectory Remington 521 T Sight
Height 1.5 Sighted for 75 yards MV= 1411 fps BC= 1.05
0 yards - 1.5 50 yards +.96
75 yards 0 100 yards - 2.73
Trajectory High Velocity 40 grain
Long Rifle solid Sight height 1.5 75 yard zero MV= 1255.
0 yards - 1.5 50 yards + 1.27
75 yards 0 100 yards - 3.31
It is immediately apparent that the
string is stretched tighter in the way of trajectory. Recall also that the
37-grain HP loadings have less in the way of BC and are likely to produce
velocities somewhat short of the published data. All this adds up in the plus
column for the Velocitor in its down range performance. In so far as
consistency can be guessed from five round strings, there appears to be little
deviation from the performance of the general run of High Velocity Long Rifle
rounds. Extreme spreads were: 521T 43 fps; Ruger Bisley 49 fps; Smith 617 81fps.
By contrast, Stingers and other Hyper Velocity rounds frequently show much wider
spreads from some handguns.
Comparisons of velocity results
among different handguns often turns up some surprises. I have regarded my 617
as a fast handgun with the usual run of rimfire ammunition. On this
occasion the Bisley actually cranked up the volume significantly in the
velocity/energy department(s):
0 50 100
Remington 521 T 1411 / 177 1187 /
125 1042 / 96
Smith 617 6 1151 / 118 1020 / 92
935 / 78
Ruger Bisley 6.5 1192 / 126 1045
/ 97 952 / 81
The data tells us that the rifle
will effectively do at 100 yards what the two revolvers are doing at the
fifty-yard line. It is also noteworthy that the Velocitor retains about the same
velocity and energy at 50 yards as these revolvers produce close to the muzzle
with the general run of Long Rifle Hollow Points. They get about 100 fps extra
velocity over the High Velocities and 150 - 200 fps LESS than the mid 1300 fps
range recorded with the 31 grain Stingers.
I did my more or less formal bench
shooting from the twenty five-yard bench using the 617 equipped with an
aim-point electronic dot sight. Three five round groups averaged out at 1.03.
This is somewhat better than the 1.1 average I had recently obtained with
Stingers and very close to the sub one-inch averages with Remington and CCI
hollow points. Practically speaking, the accuracy results are: (1) extremely
good; and, (2) do not come up to the full potential of the round since my
imperfect shooting is part of the mix. I would not be prepared to say that the
round is any more or less accurate than the others mentioned but would venture a
strong guess that for any practical purposes it is every bit is good.
With the shooting light failing and
the sights fuzzy, I fired one five round group with the iron sighted Bisley. It
came in at 1.7 with four of the rounds clustered just a bit smaller than 50
caliber.
Given the high performance of the
Velocitor load, it is ok to wonder about bullet performance. With this in mind I
performed a quick and dirty, suggestive but not definitive test. This consisted
of shooting two water filled plastic jugs at 50 yards with the 617/dot sight. My
tables tell me that it arrives at ground zero doing 1020 fps. Neither water
bottle showed any significant exit expansion - although the water did spray out
in a generous manner. One bullet was recovered from a wet, but not soaked
telephone book behind the target. Penetration was deep and bullet distortion was
minimal. Another gallon water jug was hit at close range from the Bisley at
about 1170 fps. This one did expand to .325 in the form of a pretty mushroom and
likewise penetrated deeply into the telephone book- this after ripping a
six-inch tear on the front and back of the gallon water jug.
Sectioning of a bullet revealed a
vestigial, shallow hollow point on the order of the old Dyna-Point Australian
rabbit killers. It leads to the conjecture that this load is designed with the
thought of taking edible small game at somewhat extended ranges.
The Velocitor lives up to the
advertised claims of enhanced energy and loses the finicky nature often observed
in earlier hypervelocity rimfire loadings. I plan to add this one to my
selection of .22 working loads.
