I'm looking to design a non tumble lube 500 S&W bullet with the following criteria
1) 700 grain weight - wheelweights - .700 nose length - BTAN design - 0.150 bore ride length - 93% meplat - 0.4 grove to band ratio.
I figured it out - the 0.4 grove to band ratio was to high resulting in V shape between the bands. 0.9 ratio solved that.
Thanks in advance.
