BALLISTOL<br />

The perfect interaction between<br />

firearms and ammunition is<br />

crucial for high precision.<br />

Ammunition of the same<br />

calibre and type from different<br />

batches or different manufacturers can<br />

feature different ballistic properties due<br />

to distinctive manufacturing processes<br />

and compositions.<br />

In order to quickly regain the<br />

accustomed accuracy after an ammunition<br />

or batch change, a basic cleaning with<br />

subsequent firing is highly recommended.<br />

The current legal situation forces<br />

many shooters to change from projectiles<br />

containing lead to lead-free types.<br />

Lead-free ammunition features different<br />

ballistic properties than lead-containing<br />

projectiles. In terms of cleaning, however,<br />

both ammunition types hardly differ.<br />

Required equipment: Barrel cleaner,<br />

gun oil, accessories (pieces of felt +<br />

cleaning rod).<br />

Layers of depositions form inside the<br />

barrel. These alternately consist of soot<br />

and powder residues, as well as copper<br />

and tombac depositions. Ballistol Robla<br />

Solo MIL Barrel Cleaner removes<br />

copper and tombac without leaving any<br />

residues. Since then, hardly any other<br />

barrel cleaner has achieved nearly as good<br />

cleaning properties as Robla Solo MIL.<br />

Soot and powder layers can be removed<br />

with efficient gun oils like Ballistol<br />

GUNEX or Ballistol <strong>Gun</strong>Cer. The<br />

tried and proven Ballistol Universal-Oil<br />

provides good service here, too.<br />

Above mentioned layers of depositions<br />

have to be removed in changing cleaning<br />

intervals layer by layer. For cleaning,<br />

the individual agents are applied on a<br />

cleaning patch, pieces of felt, tow or wick,<br />

and pulled or pushed through the barrel<br />

from the chamber to the muzzle. Years<br />

of practical experience have shown that<br />

Ballistol felts offer decisive advantages<br />

over other cleaning utensils. They<br />

optimally adapt to calibre size and ensure<br />

suitable contact pressure during cleaning.<br />

First, soak one piece of felt in gun<br />

oil and slide it from the chamber to<br />

the muzzle through the barrel. After<br />

waiting for about three minutes, remove<br />

the soot depositions by passing dry felts<br />

through the barrel. The cleaning effect<br />

can be seen in a discolouration of the<br />

felts. When heavily soiled, soot turns<br />

dark grey to black. Once this has been<br />

removed, it is time to dissolve the copper<br />

and tombac. To do this, soak a felt in<br />

Robla Solo MIL, run it through the<br />

barrel and let the cleaner work for five to<br />

ten minutes. Then remove the dirt with<br />

felts. The discolouration of the felts this<br />

time shows green or bluish tones. The<br />

two cleaning steps should now be carried<br />

out alternately to remove the layers on<br />

top of each other. If neither dirt nor<br />

colour residues are visible in either case,<br />

the cleaning process is complete. For<br />

corrosion protection, it is recommended<br />

to saturate a felt with a little oil and then<br />

pull it through the barrel.<br />

In case of extreme contamination, the<br />

barrel can also be filled with Robla Solo<br />

MIL. The barrel is sealed at the muzzle<br />

and filled up to above the chamber with<br />

Robla Solo MIl. Damage to the barrel<br />

is thereby excluded. The rifle is to be<br />

placed in the gun cabinet overnight<br />

with the muzzle pointing downwards.<br />

This procedure must not be used for<br />

gas pressure loaders with a gas channel.<br />

Cleaning must be carried out the next<br />

day. Ballistol also offers intensive felts.<br />

These contain fine brass fibres and thus<br />

produce a more intensive mechanical<br />

cleaning effect.<br />

After thorough cleaning, it’s off to<br />

the shooting range. Here the weapon<br />

is tested for precision. In addition,<br />

ammunition and weapon adjust to each<br />

other and then show the usual reliable<br />

accuracy.<br />

A thorough cleaning of the weapon<br />

is not only important when changing<br />

ammunition. Deposits do not only<br />

influence the internal ballistics, but<br />

also the projectile velocity. The DEVA<br />

e.V. was able to determine that bullet<br />

lubrication in barrels affect the muzzle<br />

velocity (V0) and respectively accuracy.<br />

Due to reduced velocity of a bullet, it<br />

can be assumed that gas pressure in the<br />

barrel of the weapon also increases. This<br />

endangers the shooter due to damage to<br />

the firearm.<br />

As the inventor of gun oil, Ballistol<br />

recommends basic cleaning with the<br />

chemical barrel cleaner Robla Solo MIL<br />

at least once a year for hunters. With<br />

a higher firing frequency, as is usual<br />

for sporting or professional shooters,<br />

correspondingly more often.<br />
