If all I had was a .270 and wanted to go elk hunting, I'd take it!
I'd find some ammo in 150 grain and preferably with a bonded bullet or a Nosler partition.....A-Frames would be superb!
You might want to see what Federal has to offer.....but I'm sure Remington and Winchester offer premium ammo too.....darn stuff gets spendy!
Yes.....you can also just get 150 corelokts or power points too.....but I'd prefer a bonded bullet!
