This is something that has bothered me for a long time. Actually ever
since my first reloading manual in the late 70's.
I've noticed when a new caliber comes out the bullets have high BC's. At
the time of my first manual the newest was the 7mm Rem Mag. BC's
were higher for the newer bullets then any other caliber. I wondered why
but never looked for a reason.
Today I was looking at BC's for the .204, Sierra lists a 40 gr bullet with a
BC of .287, pretty high for such a small cal. But look at .224, the
absolute best I see is .272 for a 55 gr.
It's bothering me that newer seems better. Are they making newer
bullets for newer calibers more pointed? Or is it my imagination?
