yea, you'd still be amazed what I hear in that respect.
I had a guy at the hunt club tell me I can't shoot cast lead out of my rifle at 2400fps without having to 'scrub' the barrel afterwards.
I offered to let him shoot my gun but on the condition he had to shoot it 50 times and then check for leading. He declined. I suppose he didn't want to go through 50rnds of kick you on your butt ammo out of my 7lb 35 whelen with full house loads.
