Seasoning a bore is a practice that ended when the barrels quit being made of cast iron, or it should have anyway. The steel in modern barrels does not allow that kind of infiltration. A modern barrel is best kept clean and then coated with a good protectant. Mine have heavy mineral oil in them as a test right now.
I don't know what brand gun or style gun you have. Some guns it is best to never put a liquid protectant in because it gets around the threads of the drum and breech plug. When loaded for long periods, a little bit of oil bleeds out of the threads and can cause misfires. The CVA's and the Traditions fall into that group. When I removed the drum from a couple of the CVA barrels lately, both showed the same problem. Lots of oil in around the drum threads that can leach into the powder. How many times have you heard someone say, it always goes off at home? I believe that is one of the primary problems people have with those brands of gun when they tell you it did not go off in the field. Several years back I discovered that storing the guns upside down at home with a dry paper towel all the way down the barrel on the ramrod increased the reliability when they had been loaded all day or several days when I am out hunting. I figured it was drying something, but I never knew what until recently. The powder chamber is still shiney on my oldest rifle, so the liquid scrubbings and protectants did not hurt anything that way. My primary hunting guns no longer get liquid oils and protectants, and they also do not get anything that doesn't evaporate quickly used cleaning them.
Hope that helps! My target/goof off guns still get cleaned the way they always have. If I use a gun hunting that has been cleaned that way and has had oil put in it, I remove the screw and add a 2 grain prime directly in under the nipple. If the nipple isn't clogged, when the hammer falls, the gun goes off!
You have a nice day! Do a search and there are cut away pictures of a CVA/Traditions guns breech system.
