I also don't see a big enough difference between the Nosler, PRC and WM.
The throating thing is mute for me. I run A191 chambers for my LR stuff so there is no advantage with the PRC on a Rem 700 platform.
Recently bought my first 300RUM, just to compare and run some numbers, but still can't source ammo for it or dies (Dies are being located for me by a member here)
Have had a 30-378 Weatherby in the past, but that amount of powder for the velocity gain was just ridiculous...a pound of powder didn't go far. Same thing with my 338-416 Rigby Improved 45°. Powder usage is ridiculous also, but I only shoot that a dozen times and normally only 40 rounds at a time.
I have never really gone for all the hype when new cartridges come out.
I don't have a man bun, in fact I shave my head and have a foot long goatee beard, so no Creedmoor's in my safe.
I have a 6.5x47 Lapua instead. Lol.
Cheers.
