I have a question. I have a Thompson Center Fire Muzzleloader it has the stainless barrel. I was told not to use the aluminum rod that came with it to load the gun. i was told that it would scratch the barrel. i wouldn't think it would being aluminum is softer than stainless. Is there any truth to this. I was also told that i should not run a brush down the barrel to clean it simply use hot water and soap to clean it when using the triple seven powder. Also to use pellets instead of the powder because he said you cannot get an accurate amount when using the powder and that the powder cannot be packed as well as the pellets. is there any truths to these. i think i am dealing with an idiot. Please help me i just bought this gun and i am new to this.
