I was wondering if ladder tests ever do not work or tell you absolutely nothing? I did a ladder test with a 300 wsm 180 interbonds and rl 17 and there were no bullets close in charge close to each other, also, when i have shot rl 17 over a chronograph the velocities were all over the place. any comments or suggestions on this? anyone have better luck with rl17? i also did a ladder test with 760 and there were 2 very distinct powder ranges where there were "nodes" also, on a chronoraph velocities are predictable. any inputs or comments would be appreciated. also, it seems no matter wht bullet, the 760 at 64 grains does well, also, with different primers. But velocity is not the best from my wsm with 64 grains of 760 which brings another question, what kind of velocities do people get out of wsm's?
