Most people do not understand seasoning a barrel. When I season a barrel I first scrub it completely clean then I take everything off including the breach plug I put it in an oven and hold it at 200 degrees for about 10 to 15 minutes,then using insulated gloves I wipe down the inside of the barrel with BB. I have Hawken rifles I won bought or built [one of each] in the 1965 to 1978 period that have never had any thing else used in them. Now none of them have ever shown any rust. The one thing I would mention about BB is that it is a waxy substance and if you don't use some thing to clean out the excess when you clean the gun it can build up and will affect accuracy. Lee
