In using rifles to the outmost accuracy,and full potential,it is nessesary to
clean the barrel regularly.A hunter shooting a rifle few shots in a single
day,should clean the the barrel at end of day.A match shooter shooting in
competition cleans barrels after 8-15 shots.
It is a good rule to clean barrel when 20-30 shots are through as a maximum
shots fired.
This depends on size of cartridge case,and bore diameter.The larger the
cartridge case versus smaller bore diameter,then the more frequency is needed in
cleaning.

Cleaning Method 1.
After shooting X numbers of shots,the target, varmint or big game shooters
should use following method.
Wet 2patches with cleaning solvent (I use Shooters Choice),push from rear,up
front through barrel.This takes all loose fowling out.
Next it is best to brush the barrel with copper brush,soaked in cleaning
solvent,about 10 passes,through barrel.Add solvent to brush after few passes,at
muzzle end when brush is out of barrel.
After these passes 10 maeby 20 depending on quantity of shots fired and
condition of barrel,2 dry patches are pushed through barrel from rear.
Now the barrel should be almost clean ! To clean better it is advisable to soak
a plasic brush or fiber brush with solvent and wet the bore of barrel ! Let it
stand overnight,and check color of solvent next day.
It may come out light green or strong green,depending og fowling in barrel.If it
comes out strong green,brush some more with copper brush,and repeat wetting bore
with solvent,and let it stand overnight.
Wetting barrels is only advisable with safe solvents,read the bottle
instructions.Some stronger Ammonia blended solvents can damage barrels if left
too long in barrel.
It is advisable to leave barrels wet until next shooting starts.
URGENT ! DRY BARREL OUT BEFORE SHOOTING .

Cleaning method 2.
Some Rifles can have rough bores,and fowl badly.
For cleaning them it may be nessesary to use stronger Solvents Ammonia
blended.Use the Ammonia blended solvents carefully and only for soaking wet for
15-20 mins.Don´t brush them in with copper brush,this will ruin brush,plasic or
fiber brush.Even abrasives may be used to get out severe fowling,but work
carefully with them ! Best is to use patch rolled around a cleaning jag and push
through barrel in short strokes,gradually towards the muzzle end.
After using Ammonia blended solvents,and or abrasives,it is advisable to use
milder solvents to clean barrel and do the color check overnight !

When cleaning process is done it is good workmanship to drye out chamber of
gun,clean locking lug aeria,inside of action and put small dips of grease on
locking lugs.

Good Shooting !
