I clean at the range when the barrel is hot. Here’s my advice and regimen. Use plenty of solvent. Anyone who knows me will tell you I go through it like it’s free. Solvent is your friend, not elbow grease. Clean brush with alcohol before going to each subsequent step. Spray alcohol 70-90% cuts the stuff quickly. Not a fan of brake cleaner.
ALWAYS WEAR RUBBER GLOVES AND USE AN O-RING SEALED BORE GUIDE, NON NEGOTIABLE. YOU AND YOUR RIFLE WILL BOTH STAY HEALTHY.
COVER YOU STOCK WITH A STOCK BOOT OR PROTEKTOR LEATHER COVER. AND HAVE A RAG ON TOP OF THE BOOT/COVER TO CATCH THE GUNK! HAVE PLENTY OF RAGS!
1. Use a firm nylon brush with lots of Sweets mixed with J-B bore compound. I mix them in a 4oz bottle. It will look like brown pancake batter. I put some stainless steel ball bearings in the bottle to break up the JB. Do about 25 strokes. I also short stroke the first 5” of barrel here and in the next step. Push out with patches until that brown gunk is gone.
2. Now go at the barrel with straight Sweets on the nylon brush. It will get frothy like a rabid animal and that tells you the bore is saturated. Do about 25 strokes. Push out that gunk with patches until they are clean. Again, clean your brush with alcohol before going to step 3.
3, Next use Butch’s Bore Shine on the nylon brush with lots of it rolling through the barrel. This is cutting the Sweets left behind and getting any let over carbon. Again, use the solvent like it’s free. 25 strokes or so. When you patch out the barrel at this point the patches are pinkish-orange like the solvent is coming out of the bottle it came from. Good sign that you barrel is getting clean. Again, clean your brush with alcohol.
4. Remove bore guide and swab out the chamber to remove solvent left behind. I use a Dewey Chamber cleaning rod chamber mop that’s covered with a 3” patch. Return guide to bore when both chamber ad guide are clean.
5. Now apply Wipe-Out Accelerator with your nylon brush. It will foam up. Leave the Accelerator solvent in the bore and apply a shot of Wipe-Out spray in foam solvent until it oozes out of the muzzle. You can let the two chemicals do their magic for 15 minutes while you get a cup of coffee. Clean the brush with alcohol before getting your beverage.
Push this solution out until it’s gone. Remove the guide and swab the chamber and clean the guide.
6. Lightly oil the bore with Montana Xtreme bore conditioner.
7. Enjoy your coffee. You’re finished.
This takes me about 10 minutes from step 1 to 5.
I hope this is helpful.
