High Noon,
Yes, 100 fps (or more) can make a definite difference at longer ranges, and I'm not talking about 500+ yards but "typical" hunting ranges. Have seen some flat-based spitzers expand minimally at ranges under 300, and not by "guessing" they didn't expand much by looking at entrance and exit holes, but by recovering bullets, often from animals that didn't die very quickly even when shot well through the chest.
The higher the retained velocity, the less likely this is to happen--and a higher-BC bullet will often catch up to or surpass a typical flat-based spitzer in velocity at 300 yards, even when started as much as 300 fps slower. When started only 100 fps slower, it will catch up far sooner, and after it catches up will retain even more velocity as range increase. Along with expanding more reliably, it will drift less in the wind.
Have seen this over and over again over the years, and not just at 300+ yards. Will be posting a column on this very subject next week, with far more details. If you want to discuss the subject more after that, then will be happy to accommodate you.
