I used to shoot a .270 for deer, i tried every ammo under the sun but i can honeslty say my .270 was not picky at all in fact it preferred the cheap stuff. I used 130gr Remington Corlokts and honestly they shot the best out of my .270. The federals shot well too.
I shoot Primarily Federal Ammo out of all my guns, My .300WSM Federal, along with Shotguns, hand guns and other various sporting calibers. But the cheap stuff out of my .270 worked great. Try them all, but if your just shooting whitetails 130gr Corklokts are great. I shot a 9 point at 430yards with 130gr Corklokts out of my .270. Thats tuff to beat. Not to mention is about the cheapest bullet on the market and can be found at every store across the nation.
