Klikitarick-I too am quite suspect of loads that are near a max charge,as we should be.I take absolutely know data reguardless who it is from unless there is pressure data with it.There is a lot of it on the internet and from some notible people who some might just take there word for it.Not me.When I work up a Hunting load,I use the chrono and other factor's to determine when I am close to max.The classic signs don't show up at 40,000 as you know.But with the chrono and case expantion which increases consistanly with increases in powder charge and recoil,one can get pretty close with the chrono being the first line of defense. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
