270 bullet for whitetail??????

You may be splitting hairs. If you're not getting an exit wound your bullet is expending all of its energy on the animal which results in quick kills. You don't need an exit wound if you don't need to track .

I have the same problem with my .257 Weatherby when I take a deer inside 200 yards. The velocity is so great with this round that the bullets (BT and Accubond) come apart and destroy everything internal. Beyond 200 yards the velocity is low enough that the bullet performs as advertised and I get a pass through. That may be an issue with a .270 if you are shooting less than 100 yards.

If you want a pass through, take look at a premium bonded bullet like a Barnes TSX in 130 grain.

Not trying to be argumentative, but to clarify the statement above, I wasn't talking from a ballistic coeffecient prospective. I should have been a little more clear about that. I was talking from a trajectory prospective...

The BC is about trajectory; it tells you which bullet flies thru the air better. Consider the following from a brochure on Federal Premium ammunition, with .270 Win. Sierra GameKing BTSP bullets, both zeroed at 200 yds.:

130 gr., MV 3060, -6.5 in. @300 yds., -19 in. @400 yds., -38.5 in. @500 yds

150 gr., MV 3000, -6.5 in. @300 yds., -18.9 in. @400yds. -38.3 in. @500 yds.

Notice the trajectory is virtually identical (due to the higher BC of the 150gr. bullet), but the 150 gr. will deliver much more energy when it gets where it's going.

Sasquatch, how big are your deer up there? Down here they run small, usually less than 200 pounds, which means that a 100 grain 6mm projectile will pass through them.

Decent-sized mulie bucks are around 225-250 lbs., seldom much bigger.

Both .270 and .308 caliber projectiles (of bonded construction) will usually pass through them, which is a good thing. Most of our shots where we hunt are from 100yds. to 250 yds.

The last three I remember were 100 yds., 184 yds., and 202 yds., using a range-finder.
