Just load the 130TTSX and don’t worry.
My backpack elk rifle is a 308 Win. Couple years back I shot a big cow quartering towards me with the 150 TTSX (2800 FPS). 1 shot, it died. I decided I wanted more velocity to ensure expansion so worked up a load with the 130 TTSX (3050 fps). Waited for a broadside shot on another big cow, 1 shot and it died too.
Neither animal took a step but I am pretty patient and selective on my shots. Both were pass throughs.
I just think of this combo as a short action 270 Win.
