Barrel "Conditioning".

[Mr_Ed]

With regards to Barrel cleaning, has anyone else noticed that their EV2 needs its barrel cleaning after around 500 shots or so as it starts to go off.

I ask as this is what i'm finding.

Would it perhaps be better if i polished the barrel (internally of course).
Has anyone else done this and what were their results like afterwards?

And finally, what is the best way to polish a barrel up?

Many thanks,
Steve Ed

Best method is "Hand Lapping" you need a proper cleaning rod with a swivel handle,and the barrel is best removed from the gun.Using molten lead you make a plug for the barrel onto the end of the rod you then use fine jewelers rouge as a polishing medium or if you fancy spending a bit then the diamond polishing pastes are excellent.You then put the polishing medium onto the plug and a bit into the bore ahead of the plug and work it back and forth keep checking that the plug is still fitting the grooves of the rifling as you progress.If the bore is choked then be wary of going too near the end when you have polished it a bit then concentrate on the rifling leading up to the choke.You can measure where the choke is by pushing a pellet slowly up the bore with the rod before doing anything else.Take the measurement from the rod and mark this with chalk or a pencil on the outside of the barrel as well as on the rod itself (I use tape on the rod.) This is also good for showing up any tight spots in the rest of the bore too and they should be marked on the barrel and the rod too.These are then worked on more than the rest until the bore is feeling smooth up to the choke.
The other method is fire lapping (Fire arms owners will know about this method ) you impregnate some Ammo (I found the Milbro twin rings to be very good for this) by rolling them between two flat surfaces and the polishing medium Use some plexi glass or similar start with coarse and work your way down the grades until you are using something like T cut metal polish.Solvol Auto Sol is good for the stage just before the T cut polish as T cut is finer.fine grinding compound from the Auto store is a very good first stage polish.Use around ten pellets for each grade of paste.Smokers Tooth paste is very good for this too by the way just use about 15 for first stage then go to Solvol then T cut for 5 shots to finish.Test the bore again by pushing a pellet up it slowly feeling for any rough spots or tight spots other than the choke.
Clean the bore and then test for accuracy.
All things being equal unless there are tight spots in a barrel I just use the fire lapping method and have had great satisfaction with it for 99% of the barrels I have had to polish.
If your crown is in good shape then kiss it and do nothing else to it, but if it looks dodgy or you are not sure if it is good then a touch up using a brass domed screw of the slotted head variety can be used to polish it up using the paste too.
Polishing the whole bore has the side effect of making the probe seals on PCP guns last a lot longer
