Yes, at the same PF.

 

You can load a heavier bullet slower (lower PF) and NOT hit higher.

Either I just learned something that I'd never heard of before or "missed it" just did an excellent job of pulling my leg.

 

I just don't know which.

you learned something.

It all has to do with dwell time in the barrel. A faster bullets will hit lower on the target. So, if you loaded a 147 with a higher velocity than the 124, the 147 would strike the target lower. But in general a heavier bullet traveling at a lower velocity spends more time in the barrel, therefore strikes the target slightly higher than the quicker 124 grain bullet with less dwell time.
