Just my opinion Cayugad, but I believe the 300 is a little to solid to shoot a whitetail with. The 300 grain is a Protected Point according to Nosler you and I would look at it and call it a "soft point" with a partition behind it. The 300 is really built for penetration
This is the bullet I load and hunt elk with because I (think) I need more more penetration against the thicker skinned elk. It really does the job there. I have shot a couple of deer with this bullet (in frustration becuase I have not seen and elk or a really nice buck) and at the closer ranges (75 yards and under)it penetrates to well - goes right through - the deer is dead but it takes awhile for the deer to know that. While with the 260 the bullet still passes through (bones and all) but the hydrostatic shock of the HP litterally blows up the vitals.
That would be my assesment of the two... it is just the expsense that is driving me nuts....
