Hi James,

I'm being lazy......and not looking it up......but I suspect the 180 grain .277 bullet has a sectional density equal to....or greater than the 220 grain .308 caliber bullet. Which means it should penetrate as well or better than a bullet of similar construction. Which would also make it appropriate for nearly the same uses as one would apply a 220 grain bullet from a .30-06. (For those people that only have one rifle.....it being a .270.) Though you'd give up frontal area.

I know personally when the wife and I were looking for a .277 bullet that would give great penetration on heavy animals.....and still shoot reasonably flat.....we chose the 160 grain Nosler semi-spitzer Partition. It worked very well for us in all circumstances we used it in!

At any rate......it just provides more options for rifleman desiring to use a .270 of any stripe......on really heavy game! Making a really good cartridge....even better.
