For deer hunting, I would select the 130 grain Ballistic Tip. You don't need a tougher bullet than that. My preference with 130 grain bullets is IMR 4350 as I have so much of it. However, H 4350 is fine, too. According to the late Ken Waters, the most accurate powder with 130s is IMR 4831. I have found it to be very accurate as well. Of course, H 4831 is the classic Jack O'Connor powder.
Remember to start low and work up with your powder charges. One custom Mauser 270 I loaded for wouldn't take more than 53 grains of IMR 4350 under a 130 grain Ballistic Tip. My current 270 - and I have owned about 12 - is a custom FN Mauser. It has a 24" Shilen barrel. It won't take more than 55 grains of IMR 4350 with a 130 grain bullet. My current load is 54 grains under a 130 grain Barnes TSX for about 3,050 fps. 55 grains gives me another 100 fps.
Many factory 270s I have loaded for would accept 56 grains of IMR 4350. In my many factory (usually Remington) 270s, 57 grains of IMR 4831 was the fastest and most accurate load.
Good luck with your loading project.
