Step 1
Scrub out your gun bore with the proper size Phosphor bronze brush and use Bor-Solv supreme bore solvent. This can if used vigorously remove all powder fouling and residue. Occasionally a Bristle brush might be preferred to be made of natural hair it is hydroscopic. This fact will help this brush
308 Lower Receiver retain more of it's bore solvent chemical and for an extended period. In some applications a bristle brush can therefore be a marked improvement over a phosphor bronze brush. This process however, has become more commonly used in Europe.
Step 2
After scrubbing out using both sides of a Herringbone 4"x 2" patch in a Split brass or Nylon jag. This can remove all of the contaminated solvent. The split jag is utilized by inserting a patch midway and longitudinally into the split and then rotating the patch in your turn in the direction you are likely to tighten the patch and also twist the rod in use. Always check the chamber when cleaning and if there is powder residue around the forcing cone make use of a Chamber brush handle with a Payne Galway chamber brush to get rid of residue build up.
Step 3
Next oil the gun bores by using a clean Wool mop and some liberally applied Rangoon oil. Rangoon being a tenacious and slow evaporating oil allows the gun bore to be stored away for longer periods than usual. Occasionally wash out the wool mop with warm soapy water. Use paraffin or turps first if the mop is extremely dirty. When the mop is dry re-soak in clean Rangoon oil and we recommend you keep the mop in a new polythene sleeve or similar container.
Step 4
When storing your gun do not forget to first relieve the stress of the main springs by inserting a suitable pair of Snap caps and dry firing the gun. Then after in the event that you install a Muzzle stuffer this can with the snap caps in position not merely keep the oil vapour inside the barrel, but will also keep the dirt out and protect the conclusion of the barrels against damage in your gun cabinet
Step 5
Before firing the gun again it is very important to get rid of all trace elements of oil. Oil remaining in the barrel however slight could seriously rival the barrel walls as a result of hydraulic conversion process. Remove all superfluous oil with a patch and jag turning the patch over until it is clean. Always check the chamber before firing and if there is powder residue around the forcing cone eliminate it with a chamber brush. We advise you never to force a Payne Galway type chamber brush down the barrel as this sort of brush could eventually come apart and might also damage the gun.
Tips and Final Word...
When cleaning a rifle or pistol use the same technique as for a shotgun except replace the split brass jag for a Diamond jag and change patch to the natural flannel type Rifle patch. To use the diamond jag place the jag diagonally throughout the patch by the end and rotate before the patch has wound fully around the jag. If the patched jag is too large for the bore in diameter, unroll a little of the patch at a time, trim and rewind same before the correct interference diameter is obtained. When cleaning continue to change the patches before the last patch discarded is entirely clean.
Lastly we'd offer this good advise. Never be tempted to use a set of Gunmakers Turnscrews if you don't are absolutely sure that the Turnscrew blade has been precision ground to the exact size of the slot in your gun screw and the tool steel is properly hardened. Engraved gun screws are very costly to repair and a bad sized blade can very quickly cam out of the screw under consideration and may damage the gun screw or the final on the gun. Sometimes even injury to an individual can occur. If you're unsure always ask you gun dealer for advise. If you need to make use of a turnscrew on your gun make your it is of good manufacturer not just a cheap and poorly made import.
