[QUOTE="Michael Eichele, post: 897003, member: 1007"] Equal nose profiles, boat tail dimensions, diameters and weights, bullets that have a lower specific gravity such as copper will always have a lower BC. These will require a longer body and subsequent bearing surface to match the weight if a jacketed lead bullet. Longer bullets for a give form create more drag, period. If you make them in identical dimensions, the all copper bullets will be lighter and subsequently have less sectional density and you guessed it, a lower BC. Either way, jacketed lead will always have more potential. Then the twist becomes an issue. Imagine creating a mono metal the was to compete with the 215 vld or 230 OTM. What kind of length would they have. Twist? Well a 10x won't work. How about reduced velocity with a longer bearing surface? Copper bullets have their strengths and a place but will always have less of an advantage over jacketed lead. [/QUOTE]
