hello friends
this is the Ford kalibrgun video you can
watch the previous tree from my channel
this video is specially for the tuning
of the crickets barrels and assume I
know at the burroughs CC 450 millimeter
long choked 12 grooved to his burro the
bow is produced in Czech Republic from
cz or Cheska's prayaga a/c is today the
only company that directly continues the
tradition of the interwar Czechoslovak
arms industry the process of the barrels
are the quality of the materials is
superb the channels of the twist are
also very high quality also the barrel
is a hammer forged for superb accuracy
the cons are the barrel chrome is ugly
the choke is kind of too much and the
entrance of the pellet can be done
better at the rest of the video you will
see the improvements I have did to the
rifle and most of them are applicable to
all air rifle barrels at this picture
you can see the difference of the barrel
before see at the right side and the
left side you can see after the finish
the importance of the finish of the
channels and the barrel crown is crucial
this is the last touch of the pellet
with the gun and I will say the most
important the cleaning rod I have used
was not to clean the barrel
I have other methods to do that and I
have video on my channel harm cleaning
my rifles the cleaning rod was used to
push the pellet through the barrel and
see what is going on
watch the marks of the pellet there are
not smooth and clean this is because of
the bad barrel crowning
this was Barracuda match agent and
pellet and here is the GSP exact heavy
5.5 pellet I have did many many examples
before I moved to the crowning it's
unbelievable how manufacturer of cz
again do such a barrel crown the barrel
is really good thick enough to reduce
the vibrations good and hard steel and
perfect channels but the crowning kiss I
have no words you can judge by yourself
I did not clean the barrel with purpose
you can see where the let is layer it I
will assure you that every cricket have
the same finish I make research on the
internet and many owners are complaining
from this also I have friends owning
cricket rifles and they are saying the
same this is an expensive gun and to
sell it with barrels like this is not
right here are some more micro pictures
and until they go I will tell you what I
did to do the crowning I find a twisted
tuner that will do whatever I am telling
him to do and to have late in good shape
I mean without play delayed should be
very precise the most time and nerves
consuming tink is setting of the bore
and the center a crown that is Square to
the poor we're allowed to the pellet to
release consistently we create a tight
mandrel with brass to not hurt the
inside of the barrel we use the tool
measuring device to set the barrel
precisely through the measuring inside
mandrel when this was done the mandrel
was removed and the cut was done the cut
should be very small and following the
original cut just to remove the defect I
was planning to make a 11 degree
crowning but this will not work with the
shroud
next thing is the air transfer passage
of the borrow from the next pictures you
will see how I change the angle of the
entrance-hall
for the better air flow I use the tool
as a dremel I add inside a piece of hard
paper to protect the inside of the
barrel the magnifying glass is necessary
this is coming with LED light and that
helps to see even better when filing was
done was time to polish and polish again
and polishing again
the beginning the entrance of the barrel
where the ballot is laying was also very
rough and I fix it just a little bit not
to damage anything seems the same
machine was injuring the beginning of
the barrel the same machine that was
injuring barrel crowning
you
pushing and removing the piece of
clothes that I put inside of the barrel
to clean to keep it clean here you can
see how deep is the choke I measure it
with a cleaning rod I put some paper
scotch just to protect the inside of the
barrel I'm never using a cleaning rod
this definitely will destroy your barrel
back to the choke this is my opinion but
the choke is too strong this goes more
spend more noise and the worst is that
harm the skirt of the palate Barracuda
pellets are okay because they are with
thick skirts but GSB sir with dinner
skirts and when the skirt is damaged the
pellet is rolling you can see the effect
in some of my videos I was thinking that
the Browning is causing the dis but
actually is the choke every owner of
crickets that I know have the same
problem pellet wobbling I can be seen
through high-speed camera many of air
gun owners do not know that their rifles
are shooting wobbling pellets did I did
something about it
no I'm not going to do anything for now
because the chance to run the barrel is
pretty high
from the previous pictures you can see
how deep the pellet is going in the
barrel and here is one tool that I made
through which I am opening the firing
valve without damaging it again the
cleaning rod but this time to test is
with GSB pellet to measure how deep is
the choke
I won't get the joke
by the way do you see how the skirt was
damaged this is what I'm talking about
I made pictures from different sides of
the palette I turn the palette and take
a picture after picture just to observe
the deepness of the channels and on the
ballot
this is pellet that was gone through the
choke and this is pellet that gone
before the choke you can see how deep
are the marks with the choke now you can
see again the damage of the palate
well bar could a match have no problem
at all and you can see how deeper our
channel marks in the palate well do not
forget to subscribe and hit like on the
next video I will show you the gadgets
I'm using during my shooting and
recording or just will continue with the
pest control hunting videos see you soon
you
