I'll chime in here just to help the relection process along if I can....
To start off with the .270 is an excellent whitetail caliber...ther is nothing another caliber can do that the .270 can't for whitetail deer...period.
Secondly, what I'm suspecting here is bullet construction....I'm gonna draw some stones here, but what the heck....there are alot of new-fangled, fancy, multi-construction bullets made for deep penetration, controlled/delayed expansion. One must remember that a deer (especially the 70-100lbs deer you fellows down south hunt) is a thin-skinned animal....it is not a hog, nor a moose....you do not need special bullet construction that will delay expansion to kill a deer...I'd even say...Stay Away from these Bullets!!! They are simply not designed for deer, but rather Elk, Moose and certain Sheep. If your taking a Fail-Safe, of Swift-A-Frame or even certain Nosler Partitions and hitting deer with them at 100-150 feet with velocities around 2800-2900 fps...you can bet your bottom dollar that those bullets simply will not do what they are designed to do...they may just end up acting as FMJ's and pass right through that deer...then you go on a nice little walk for a couple of hours....
What you really need for deer at those ranges is Energy Transfer....you want to take the energy stored in the bullet and make sure it is transferred and is dissipated in the deer itself, not a tree 100 yds from the exit hole.....Soft points are excellent for deer hunting, some hunters will even tell you that flat noses are even better because they really "whomp" the deer in it's tracks spending all of it's energy on or very near impact...you will get some fragmentation, but remember that some fragentation is'nt all that bad if it happens inside the deer...it is excellent on arteries and such...get away from the 100% weight retention, 2X expansion, deep penetration/controlled action bullets for deer...get a good solid bullet (ie..Core-lokt's, Interlock's, Power-point's) and it should do just fine...
My 2 Cents...
