Yes i do agree in some respects, as far as the boat tails, their main advantage is sub sonic speeds i beleive (long shots), they hold stability better. as far as the golf ball, basically there are two types of fluid flow, laminar and turbulant, laminar flowhavin the least coefficient of drag of the two BUT it separated easily from the projectile creating GREATER drag. turbulant flow (golf ball dimples) has more drag to start out with but it better adhears so to speak to the ball. i agree with youon the trailing edge. and as for the polymer tips, they look pretty and thats what people buy i guess. on low velocity muzzle loading bullets the make little differance out to 150yards,
