There is a great deal of difference between a 150 gr .277" bullet and a 150gr .308" bullet.One is very light for caliber,and the other is very heavy for caliber.
There'snot much difference between the .30-06 and the .270. I was just making a point cause he was asking about the 150gr.
For optimum penetration and expansion for a .270 and or a 30-06 on deer sized game your SD should be between .190 to .242, which covers 100 grain to 130 grain bullets for a .270 and 125 grain to 165 grain bullets for a 30-06, for elk your SD should be atleast .270 or better for both calibers, a 150 grain pill from a .270 has a SD of .278 and a 180 grain pill from a 30-06 has a SD of .271.
I know to alot of folks this is french to them. but this also where alot of folks mess up and choose the wrong bullet for their game. just another 2 cents
edit: wanted to add this maybe this will help translate the french, a 150 grain bullet in a .277 dia has a SD of .278 which is fine for elk, where a 150 grain bullet in .308 dia has a SD of .226 which is just barely middle of the road for deer.

To tell you the truth most folks can't tell the difference when shooting freehand at the range they group pretty close together out to 100 yards. From the bench out to 100 yards there is a little difference. Think about it there is no powder and only 15 gr of weight difference. Unless you are shooting over 100 yards I woulden't worry about it. One thing to remember tho is when you are out in the back country and need ammo cause you lost yours or whatever most back country stores carry 150 amd 180 gr ammo not many that I found carry 165.
