At 296 grams and 155mm long, it
complimented the gun perfectly offering
effective suppression. The trigger blade is
slim at 7mm and I would have preferred
some chequering or grooves but it gave
deceptively light pulls under the 2lb mark. It
wasn’t a glass break but no creep could
really be felt, certainly no grittiness and
overtravel after the shot was minimal. For a
necessarily complex action design, the
trigger was easily judged and pleasantly
dependable in use.
QUICK OFF THE MARK
I ran a selection of ammunition through the
gun’s 1-10” twist barrel. Everything from
70-grain ballistic tip Sierra handloads to
105-grain GECO Softpoints shot within my 1”
@ 100 yards requirement. Special mention
must go the Fiocchi 95-grain SST
ammunition which became my go-to choice;
often capable of 0.5” 5-shot groups and
utterly reliable out to 300 yards and NO hard
extraction in 200 rounds.
All showed slightly higher velocities than
expected from the 22” barrel, the GECO
nudging 3000 fps with Hornady 95-grain
Superformance up to 3150 fps, it’s clearly a
`fast` tube. The superb quality control of
heat treatments and hammer forging also
ruled out any wandering zero through a hot
barrel! The barrel cannot be cleaned with a
rod in the conventional manner without
removing it from the gun, a factor that makes
precision rifl emen quiver with doubt and I did
to start with too. But not for long! Barrel
swap has to be the fastest out there – press
the button under the forend allows it to slide
off and an 85mm lever to the lower left of
the barrel swings down to unlock it.
HEAD JOB
Removing the barrel offers two possibilities.
With the action closed, the bolt head will
come out with it still connected to the
locking abutments. It is then rotated to
remove. However with the action open it
remains attached to the carrier in the
receiver. To re-insert the barrel align the red
mark to the upper side with the action, slot it
back in and lock down the lever, click the
forend home and Bob’s your uncle.
Return to zero, the most important
aspect of any switch barrel system! I did
refi ne this method a little as to aid the job. I
placed an UNLOADED but fi re-formed case in
the chamber, rattle the action back and
forward a couple of times to lock/unlock it
and then the secret, from Merkel
themselves, is to open and close the locking
lever three times, just to allow everything to
nestle back into its relaxed `comfort zone`. I
followed these rules and found the deviation
never exceeded ¾” from previous point of
impact on the fi rst shot and defi nitely within
ammunition accuracy levels on the second.
These values alone are readily attributable to
a cleaned barrel but I tried it several times
hot and cold, clean and unclean, just for fun
and it never varied any further.
COMFORT AND CONFIDENCE
It’s a very comfortable gun to carry as no
bolt handle ever sticks into your back when
slung. Cleaning the action’s internals is no
light task though, the butt is removed with a
long Allen key and then the trigger guard
assembly drops out from below after two
cross pins are drifted out. It is defi nitely a
workshop job and not a 5 minute task
although in 500 rounds, it never NEEDED
cleaning to function. But the internals
defi nitely sounded a little gritty on occasion
and in some environments, could foul
terminally in my opinion.
It shoots well from all positions, partly
because it requires little physical movement
to reload but also stock ergonomics and
subtle features like the hard polymer heel to
the rubber buttpad. The metalwork and
furniture proved durable, only a careless
encounter with a jagged rock has lightly
marked the gun anywhere other than
characteristic brass marks on the rear face
of the ejection port. It has defi nitely become
a rifl e I will be sad to see go, and I can
forgive its minor character faults, as its
benefi ts far outweigh them.
If you remove
the barrel with
the action
closed, the bolt
head comes
out still locked
to it, but is
easily removed
Barrel removal
is VERY fast
and beautifully
smooth, you
can just feel
those exacting
tolerances
Merkel Helix Alpinist
243; a very different
straight-pull switch
barrel system!
