I gues I am wondering exactly which Hornady 300XTP you were actually using? Knowing that might explain some of what happened...

In theory, and probably true, the heavier bullet should penetrate more, but in fact that is detirmined by expansion and the substance(animal) that you shoot the bullet in.

As Chap says the 300 GD's have a longer shaft hanging out from under the mushroom and it will drive through farther if it and the 250 a fired at the same velocity. The 250 makes up for some of this penetration by the fact it is shot with a greater velocity - 1860fps (300 grain 1775)..

I am not going there because I do not have the PRB experiance but I would highly suspect what you indicate to be true.

I wish I could show you a pic of a 250 or a 300 hit with the resulting blood trail but all I have are hits by a .451/260 grain Nosler. BUT - I would expect the same results from either of the God Dots. This shot was on a small toe whitetail @ 170+ yards. I was down hill and quartering to me. The shot sent him straight into the air with all four feet... then his flight response took over - he made it about 30 feet. The bullet entered the chest cavity a little lower than I planned and came out behind the left front shoulder... now the impressive part for me... everything in the chest cavity was dark red jello... I may have it a good portion of the heart but there is no way i hit every organ in there. When I got him opened up - there was nothing but jello in the chest cavity... Blood trail no problem - there was all kinds of blood at the hit site and all the way to drop site... even at the drop site there was blood splatter (new term for me from the CSI shows I watch) all around the area.... he was really spraying blood. This is pretty much how I found him...
