I just remember they were close, I forgot to say I was shooting the XTP Mag, so Igoogled "XTP Mag Ballistic Coefficient" andthis shows the BC to be at .230 for the 300g XTP Mag:

So the Speer GD and the Hornady XTP Mag are pretty close to each other, which explains my POI comment of little difference.The lighter weightXTP don't nearly have theBC of the 300g, therfore better down range energy. Sorry for the confusion, my error.

The XTP Mags have a thicker jacket and therefore stay together better when hitting bone, also they can be shot a higher velocities, see this chart:

My opinion is that any bullet will do the job on "bow shots" right behind the front shoulder. If you can always put the bullet there, it doesn't matter what you shoot. However if the deer moves and you hit shoulder blade, then you want a solid penetrating bullet that expands--these are called balanced bullets, because the wound channel is large causing a quick death, hence the need for a thicker jacketed XTP (called the XTP Mag) or the Gold Dot or the Nosler Partition or the Barnes (any of them are good--PBX, MZ, TMZ, Barnes Origonals, .458 X bullet, etc). Accuracy is #1, then Penetration is #2, since you gotta get into the vitals, expansion is #3 to cause large wound channel and disrupt blood supply to brain and shoot thru is #4 for ease of tracking.
