G30, LW barrel. So I'm shooting a lot of cast now and trying different things. I got some bullets from 2 different companies. Same bullet, weight, everything, just 2 different companies. One box the bullets are kind of shiny and slippery and the other box they look like regular cast, not shiny or slippery. Load them both the same, 2 different weeks at the range. The shiny slippery boolits pretty much don't lead the barrel at all. Barely a trace after 50 rounds. The other box, quite a bit more leading, same powder and load. Not terrible lead, just more than the other bullets. The hardness is supposed to be the same for both companies. So what's with the shiny slippery bullets? I have to also mention here, that all the tips for the Choreboy wrapped around a wire brush is an awesome tip! Works great cleaning the barrel.
