I’ve used the 140 Fusion in a 6.5 Creed on elk with great success and feel very confident with them.
The .270, which I’ve used since the late sixties is basically a magnum with the 130’s.
I’ve gotten bullet splash on a couple of occasions and one of the constants was that the deer were wet from rain.
One, a smallish blacktail at very close range was hit behind the shoulder with a 130gr bronze point reload. I completely jellied the shoulders! The entrance site was a huge hole....and yet the buck ran out of sight. The off side rib cage wall was peppered with fragments.
I wouldn’t count out the Fusion offering based on one example.
If your still concerned, you might consider bumping up to the 150’s.....
