For deer there not many wrong bullets out there so long as bullet weight is 130 or 140gr. I hunting friend has use hornady ammo for years, 130gr sst for southern deer 140gr sst for large north deer and there interbond for elk hunts. But years ago he used winchester old 130gr soft point. heck we all used the basic soft points from different companies. Shoot a few and see what your rifles like best . keep of more expansive bullets off the shoulders.
I dont know the exact specs of my .270, but I've used 130gr Remington Core-lokt PSPs and know they mushroom very well from the wound channels, and acutally had found one stuck in the hide. It had mushroomed beautifully and had excellent weight retention.
I have a Savage rifle in 270, and I have been using the 130 Remington core-lokt bullets for many years, and have never been disappointed. Seems to mushroom very well and leaves an impressive wound channel. Plus, my gun groups them very, very well.
I have to admit every 270 I have hunted with was borrowed from an experienced hunter. I have never fired a bad 270 round. Most popular are the 130 gr soft points. Every time I used a 270 it was one shot one kill.
