I've been doing a fair amount of hitting the books on bullet design, etc. I was surprised to read in more than one place that bullets are designed by volume not weight. I also noticed that the benchrest bullet makers don't seem to adhere so rigidly to a/the weight designation standard. 30 cal 115s being an example (30 BR) In our world what says the 169.5 weight 277 bullet is the cat's meow. Why not 169 or 170.1? Just as an example. It seems that things have evolved since the early days of the industry that the the weight has become the 'name' for a class of bullet. Other descriptive adjectives and feature are added on to further describe a bullet. (Accubond, Ballistic Tip.......) Just wondering........... Are we stuck in some one else's box?
