RE: best bullet and weight for 270 whitetail hunting
The 130 grain bullet from the 270 has good Sectional Density. About equal to the 165 grain bullet in 30 caliber. You should have no trouble with the 130 on game up to Elk. At that pioint I would opt for the 140 or 150. Many Elk have been taken with the factory loaded 130 grainers.
