Lead vs Copper Jacket
I'm new to rimfire.
I went to purchase my first box of ammo. I asked the store owner his recommendation. He said I should avoid lead ammo and buy copper jacket instead. He said that lead tends to leave residue in your barrel. Eventually the build up will start to effect accuracy. Even with cleaning, he said you can never completely get rid of the lead in the rifling groves and that I would save myself a lot of headaches down the road by sticking to copper jackets?
I'd like to hear your opinion as to weather this is good advice or not.
