Not necessarily: the Barnes 6.5mm 126.5 grain LRX bullet is solid copper with a hollowpoint filled with a polymer tip. It measures c.35mm long (the same as a lead-cored 6.5mm 140 grain Berger VLD) which gives a length/diam ratio of around 5.2. The problem comes when you want a tracer version of the bullet….
Incidentally, the LRX has a G7 BC of .460, a G1 of .230 while the Berger's numbers are .612 and .313 respectively - the cost of going lead-free! OTOH the LRX will have a higher MV due to the reduced weight, even though the propellant space will be about the same.
