OT - cleaning bores of target pistols

[ViggoG]

A few cents worth on my own observations .


As many before have stated the bore is the most damaged portion of the rifling .

This mostly brought about by scrubbing the rod to the side as the rod is forced through the bore.

This damage will take place at either end of the bore equally, always with damage to accuracy of fire.


In addition the chamber end of the bore is exposed to driving the abrasive powder and

or residue through at very high tempratures and pressures.


Temp. and Pres. being physically inseparable in as much as temp. and pres. are directly related to each other .

Any increase in pres. causes an exact rise in temp.


Therefor 14.7 psi @ 20 deg. centigrade when raised to 15,052 psi results in 20,480 deg. cent.

and this is the temp of the abrasive particles mentioned above .

Even for the short period of time a hellish way to treat your baby and this you do each time you fire it .


This abrasive action is called bore erosion and is probably the most active cause of bore degrading other than rust and corrosion.


Any object that can become contaminated with any abrasive will cause some damage regardless of hardness of the carrier however the softer the carrier the less force that can be transferred to the abrasive to damage the bore and

or rifling.


These facts almost decree the use of bore snakes.
