Step 2: Shooting at the range. After each of the first 5 shots at the range I completely clean the barrel. I clean the barrel after each shot. I scrubb the barrel with my Basic Cleaning solvent, this is a formulation that I gained from Fred and I have included the recipe below. After I’ve scrubbed out the bore with the cleaning solvent, I run a dry patch down the bore to remove the solvent and ensure that the bore is cleaned. Then I wipe the bore with my WWII surplus gun oil, run another dry patch and load up for the next shot. I do this after each of the first 5 shots for the day at the range. Once this 5 shot string is completed, I shoot normally for the remainder of the time at the range. I swab when I have to and I load and shoot with nothing special.
When I’m done shooting for the day, I scrubb the bore out with my Basic Cleaning solvent until it is clean. You can tell when the bore is cleaned as the patches will no longer have black residue and will have a greenish coloring. The greenish coloring is normal. Modern black powder barrels are made from steel which has a general composition that is 98% Iron; ~1.0% Chromium and ~0.4% Carbon. The greenish coloring on the cleaning patch is the result of a chemical reaction between the cleaning solution and the chromium in the steel. Once the bore is cleaned I run a dry patch and then run my WWII oil on a patch through the barrel. Hopefully, there will be a break of several days before the next time that I go to the range. So every few days I’ll run another oiled patch down the barrel and inspect it very carefully. When you do this you will note that the patch should be pretty cruddy looking at the beginning of the seasoning process. That first patch after the gun has been cleaned and sitting for awhile should come out with black residue, even after you’ve scrubbed it clean and oiled it. You most likely will even find rust residues. A few days later run another oiled patch, and a few days later run another oiled patch. These 2nd or 3rd patches, before you return to the range will be cruddy as well, but each will be less so.
The next time that I go the range I again go through the tedious 5 shot process as stated before. At the end of the day, I clean the gun thoroughly with the Basic Cleaning Solution, swab the barrel dry and oil the gun as stated before. Over the next few days I’ll again run random oiled patches down the bore. You will notice that after each shooting session there will be less and less cruddy residues on these patches that you run in the days after shooting the gun at the range. If I have the patience, I have found that after 8 to 10 times to the range, with time in between to run oiled patches, I will reach a point where the barrel will have little or no residue when I run a oiled patch down the barrel several days after cleaning it. At that point, the barrel is seasoned, and you will note that the gun will load easier after successive shots and the gun will clean easier at the end of a long day of shooting. I have even seen accuracy improve in 2 of my guns, once they were properly seasoned.
For a good Basic Black Powder Cleaning Solution...here is my cleaning solution formula:
1 Liter Storage Bottle
1 Cup House Hold Ammonia
1/4 Cup Dawn Dishwashing Soap
Fill the 1 Liter Storage Bottle 1/2 full with warm to hot water. Add 1 cup of House Hold Ammonia and then 1/4 Cup of Dawn Dishwashing Soap. Mix well and top off the liter bottle with warm water.
