For the 7mm-08: 0.485 BC. Nosler Ballistic Tip. 140 gr.
For the 243: 0.43 BC. Sierra Game King. BTSP. 100 gr. (this is the only .243 bullet with a BC above 0.4 All of the 7mm-08 bullets have a BC above 4 except the Barnes Triple shock and it is 0.394.
The wound channel is significantly greater for a 7mm-08 over a 243 as well. .284 vs .243

Was just going apples to apples:
quote:
Note that with bullets of the same weight and style, such as the 100 grain .243" and .257" bullets or the 150 grain .311" and .323" bullets, the smaller diameter bullet always has the superior BC due to its better sectional density.
