Using the 150 over the 130 isnt going to make a huge difference either way. The .270 is such a fast round in either the 130 or 150 grain bullets that it is like being asked if you would rather die in a car crash going 150mph or 130mph, either way your dead. The only real difference will be if you are going to try shooting over 200 yards or so, the 130 will shoot a bit flatter. Bullet selection is the real key though. I like the Core-Lokts for a factory load, they have always put the deer down very humanely.
