25x47 or 6.5x47 for NRL Hunter

[762 ULTRAMAGA]

I'm about to order a barrel for NRL hunter matches and I'm torn between the 6.5x47 Lapua or the 25 cal version.

Given the power factor requirements I'd have to send a 134 around 2840, or I could shoot a heavier 6.5 like a 144 lrht at 2650.

I guess what I'm really hung up on is whether or not a lighter 25 cal bullet going 2850 offers any advantage in terms of recoil or ballistics over a slow high bc 6.5?

I’m fighting that same demon right now my buddy built a 25prc but I have a lot of brass and all the stuff for my 6x47 so I wanted to go the 25x47 just worried I’d have to overload to hit PF

I would check TNF and use whichever one has a higher TNF and still makes power factor.
