Quite a big difference between the two bullet weights there @Tentman even in published load data.
Nosler list their 130 weight bullets doing 3200 fps out of the PRC with H1000 (2217) and down at 3030fps with a 140 weight bullet. That's from a 26 inch barrel mind you.
With my first lot of reloads I'm back up to 2770fps with the 147 ELD-M, plenty of bang flop out a long way. I think there is also an advantage of running a custom barrel in your case, excited to see what you end up running in yours.
