here is what I do, no warranties, results may vary.
I learned how to clean a gun in the army and modified the procedure to fit my needs.
What you need:
- one-piece cleaning rod
- adapter for above to run patches (at least two sizes for 30 cal and 22)
- bronze brushes for each calibre and possibly nylon brushes
- lots of patches, 22 and 30 cal are different
- gun oil
- nitro bore cleaner
- "Wipe Out" for tough cases
- bore snake for each calibre
procedure depends on gun and state of gun; just went through a 100 year-old milsurp.
Here is the procedure for such an old girl:
- unload and PROVE etc
- bolt out
- check the bore (some times you can actually see stuff)
- disassemble gun
- run a dry patch through to check for rust or deposits
- if it's bad soak a patch in nitro bore cleaner
- let sit with the solvent for ten minutes
- run the bronze brush through a few times
- switch to dry patches and run them through once until they come out clean (this can take 10, 20, 30 ... depending on the state of the gun).
- when you are satisfied it's clean, soak a patch in oil and run it through to coat the barrel for storage. Before shooting run a dry patch or a bore snake through to get the oil and any dust out.
For the gun I just did I had to do this three times, nitro solvent, bronze brush and patches until clean. Don't get the nitro solvent on the stock if it's a nice stock.
If it's a new gun, well treated and fairly clean:
dry patch, oily patch, then dry patches until they come out clean again.
Would use nitro solvent and bronze brushes only occasionally as needed but not after every shoot. You shouldn't have to. Some guys will not use a bronze brush on expensive barrels.
If there is a lot of deposit in an old or mistreated gun "Wipe Out" is your friend. Follow instructions on bottle, needs to sit for a bit with muzzle down so it doesn't flow into the action or stock. Wipe Out is especially good for Cu deposits.
While out shooting or hunting I have a bore snake in my pocket. Get's out deposit, dust and moisture before and after shooting quickly. Doesn't really replace cleaning but makes it a bit easier, if you get stuff out right after shooting and before you transport the gun home. Bore snakes need to be washed occasionally as they accumulate dirt from the guns.
For the rest of the gun, disassemble, wipe off any dirt with patches or a dry cloth, apply light coating of oil and reassemble for storage.
As I said that's what I do, depending on the gun. There are different opinions out there on what's best but this seems to work for me. Today's quality rifles, stainless barrels and modern ammo it doesn't require all that much. Old milsurps are a bit a different story.
Good luck, don't go overboard, spend your time shooting not cleaning.
