Correct Cleaning - Pull throughs are good for lever actions - I may possibly use one in the field hunting if I get debris in the barrel muzzle. bar that i would not have one in a quality barrel.
many say you do not need to clean Rimfires or centre fires until groups start to spread, Q- why do the best competition shooter and Benchrest shooters clean their expensive barrels often to correctly maintain them and their accuracy performance.
Many will say but we always use a bore snake or do it this way well they are always wrong or not so correct. Proper preparation and safety helps with proper performance in all things especially the shooting sports.
For all Bolt rifle - I remove the bolt use a action Specific Delrin Bore guide- Anschutz model 54 are available form many, I import mine from Sinclair's Int -
this was taught to me by a multi world champion Benchrest shooter:
a. remove bolt, insert quality specific bore guide,
b. using a good quality - ONE piece Calibre specific Cleaning rod,
c. put two wet patches of lead remover down the barrel to remove carbon and some lead or copper, then one dry,
d. change from jag to calibre specific Nylon Brush and soak and then scrub the bore back and forth making sure your brush is always parallel to the bore, patch out with one wet and then dry , checking if the lead has been removed in rimfires,
If rimfire check for carbon & lead ring at the throat of your breach of the barrel, if visible spend extra time just on that area I use a short rod, I cut down and have it in cordless hand drill and soak brass or nylon brush and spin at slow speed if bad and been there for a long time a whisker of bore past as slow as possible, then wet patch and dry.
e. If copper / coated centrefire projectiles then use a good quality calibre specific brass brush soaked in copper and lead remover, scrub the bore them patch with wet, then dry's- check for any signs of copper. if signs the repeat buy wetting the bore with soaked copper removal patch - leave for 15min if possible or more then scrub with brass brush - patch out scrub with Nylons then patch out - if still signs of copper fowling, cap the muzzle and use some sweets to soak the bore - then scrub and patch out and then the nylon and patch out of a clean barrel bore. if storing put a lightly oiled patch down to coat with film of preventive lubricant- DO'T FOEGET TO CLEAN THAT LUBE OUT BEFORE TAKING IT AWAY FROM HOME TO HUNT OR RANGE just a wet then a dry patch. Do it as if it is a winning barrel every time, and it will look after you.
