[QUOTE="Brown Dog, post: 177504, member: 1622"] Bloody Hell! Was Evil Kneivel's motorbike spin stabilised?!! :) :) What RPM? :) and those long passes, are they gyroscopically stabilised too?? So to answer your question change 'bullet' to 'spin stabilised projectile' and YES I've already explained what's going on, and where the force comes from (the OVERTURNING MOMENT) but you fellows don't want to understand. ....and meanwhile properly stabilised shells just keep on landing point first. The firing table elevation for an L15 155mm shell Charge 8 at 24.7km is 834mils (approx 47degrees). Your theories state that the shell will retain that angle throughout its flight and land still pointing up at 47degrees. But they don't. Weird isn't it? Still, from your Flat Earth perspective, at least you don't have to worry about Coriolis ! :) Abandon Ship! [/QUOTE]
