Long Range 101 Part 44 - Cleaning Your Extreme Range Rifle

Long Range Precision Rifle Minimal Disturbance Cleaning Regime

'Clean as Needed' -- Basic Premises
a) Immediately after use in corrosive environments or exposure to water
b) After exposure to grit, dust or sand.
c) When rifle becomes excessively fouled with powder or copper (perform inspection) -- when accuracy begins to deteriorate or significant MVV is encountered

Round count between cleanings may vary dramatically based on use and environmental conditions.
moisture
blowing dust and grit
general use of rifle, load dynamics and rate of fire

Cleaning STEPS:

1. Insert Bore guide into action
2. Attach a copper brush to your one piece coated cleaning rod
3. Soak brush in Powder solvent (Hoppe's No9)
4. Gently and carefully scrub bore from break using bore guide with 10 passes (NOTE: If brush exits muzzle, take care when pulling brush back through the crown that damage does not occur). Allow solvent to sit in bore while you move on to next steps. Be careful not to let solvent leak into the trigger group.
5. Clean bolt using powder solvent (be careful with rear face on lugs -- use nylon bristled toothbrush)
6. Re-soak brush in powder solvent, do 10 more passes.
7. Remove brush and attach jag to cleaning rod. Run several patches wetted in powder solvent down bore until the powder fouling is removed.
8. Run clean patches till bore is dry, if storage in humid environments is anticipated you can wet last patch lightly with gun oil
9. Clean the chamber using the appropriate chamber brush and powder solvent. (J Dewy manufacturing)
10. Dry Chamber Using Swabs
11. Remove solvent from bolt lug tracks
12. Lubricate bolt lugs with a shooting grease.
13. Lubricate bolt body and the portion of the bolt where the bolt handle is attached to the bolt body.

*After cleaning, before using the rifle in the field again, 1 to 5 fouling shots should be taken before field deployment time to reestablish powder fouling equilibrium.

Copper Remediation can be done if Excessive Copper Fowling is experienced.

Procedure:
1. Wet a patch with Sweet's 762.
2. Push the patch through breach to last 1 inch of the muzzle
3. Fill last inch of bore with Sweet's 762
4. Slowly pull rod back out towards chamber, stop when you reach the throat
5. Wait 3-5 minutes for soak, slowly push patch back out and exit the muzzle. Save solvent if you can.
6. Scrub the bore with 10 passes using patch on jag, or until clooper has been removed,
7. Chase copper solvent out of the barrel using patches wetted with WD40 followed by clean patches until completely dry.

NOTE: You will have to reestablish copper equilibrium if you did not use the Benchrest Shooters Barrel Break-In Procedure. This typically takes anywhere from 20 to 60 rounds. You will know when you've achieved equilibrium when your group sizes shrink and your MVs stabilize.

Only clean copper out of your bore if necessary. The less you disturb the bore, the less MVV and POI shift you will experience. Minimal disturbance is ideal for our shooting discipline. Only clean when needed.
