smith where he or she will give you the bad news—that your cylinder and receiver block will have to be replaced, with a $600-$800 price tag.

As Pilkington explains, never use a petroleumbased lubricant on an airgun—only synthetic.

I mentioned synthetic grease, so let’s talk about proper lubricants for modern CA guns. Never use a petroleum-based lubricant or cleaner with your airgun. If the petroleum product gets into the high-pressure line, it can diesel (ignite) and cause a potential life threatening explosion. Also, nonsynthetic oils or cleaners can cause the rubber or plastic seals to deteriorate. Most traditional firearm lubes and solvents will harm your airgun. The good news is that you don’t need to lube an airgun very often or very much. Honestly, we see more airguns damaged from over-lubing than under-lubing. If you want to lubricate your gun, all you need is a very little amount of synthetic grease on the working parts of levers or pins and a “smidgeon” of moly grease on the sear and the cylinder threads, as mentioned above. In normal use, the only user lubrication that I would consider absolutely necessary is the grease on the cylinder threads. Other lubrication can take place when you have a professional check-up of your airgun. How often should that happen? It depends on how much you use it. Top athletes that are shooting daily should have their guns gone through once a year. Schools or programs that shoot their guns half a year or so can get by with a rifle service every third year. Individuals who shoot their airguns infrequently can go six or seven years or longer. What does a full service consist of? Normally, all seals and

springs will be replaced. Valves and valve surfaces will be inspected and replaced if necessary. This necessitates disassembling the whole gun, so all moving parts will get inspected and re-lubed on re-assembly and any potential problems should be found. As I heard one shooting athlete say to another, “Getting your rifle rebuilt is a good idea, ‘cause sometimes they just find stuff.” One thing you can do to preserve the life of your airgun is unscrew the cylinder every time you finish shooting it for the day. Unscrew it enough that you hear the air “whoosh” out of the regulator. Leave the cylinder attached to the gun to prevent dirt or other foreign objects getting on the threads. When you get ready to re-install the cylinder, unscrew it all the way out first, and then start back in to avoid pinching the sealing o-ring. The reason for releasing the air is to take the pressure off the regulator springs and o-rings—the heart of a modern CA match rifle. The regulator is what steps the 3,000 PSI air in the cylinder down to around 850 PSI to give a consistent shot each time you pull the trigger. Another point about regulators on CA guns is to exercise them after the gun has set for a while. Shoot three or four shots without pellets before starting sighters to make sure that the internal rubber seals are moving as they should, as sometimes they can stick when the have set for awhile. Another frequently asked question is: Does your air rifle barrel require cleaning? There is some debate on this issue. There are those who say it should be cleaned every time after firing, and those who say to never clean an airgun barrel. Airguns don’t generate any real heat, nor do they have dirty powder residue like firearms. I have tested many airguns for pellet accuracy and, occasionally, found one that does not shoot well.

I tried cleaning the barrel, looking for improvement, and it seldom helps. I am going to say that as long as you are using good quality match pellets from RWS, H&N, Vogel or JSB, then cleaning is of little benefit. If you think it helps, don’t let me discourage you. I recommend you use some doubledup monofilament fishing line to pull a cleaning batch through the barrel. I see no need to ever put a brush or a rod through a 10m airgun barrel unless you have a pellet stuck in the bore. A barrel that has been cleaned should have 15 to 20 “fouling shots” shot through it before you start a match, as a totally clean barrel will shoot to a different point of impact than one with a normal amount of pellet wax on the lands and grooves. Always make sure that pellet holders are securely closed in your travel case. Every year we get three or four guns that have problems. When we dissemble the action, we find little chunks of pellet lead from the gun case that somehow got inside the action. For those that use a CBI (Clear Barrel Indicator), you should carry something like a sandwich baggie to store the CBI when not being used. I cringe every time I see an athlete remove a CBI and throw it on the dirty floor, then pick it up and stuff it back into the barrel at the end of the shooting session. This can cause long term damage to either the rifling or the crown of your precision airgun. All these basic rules apply to air rifles using CO2 as well.
