12" Monster barrel, 6 ARC vs 6.5 Grendel

[7mmShooter]

Hey y'all, looking for anyone who's run the 12" Monster barrels that BluntForceTrauma sells, Or any other same length barrel comparisons are helpful as well! I'm curious how close they run with their respective factory loads, say 108gr ELD in the 6, and 123gr ELD in the 6.5... The research I've done so far tells me it should be pretty much a coin flip situation at close/medium range with the 6 ARC taking the long range advantage. Thinking a 12" 6mm ARC with 92gr Cavity Back MKZ or the 103gr ELD-X could be pretty sweet little rig!

Thanks in advance

Thanks VASCAR. So the 140fps difference I've found in my research was about right then if not a little low... They're within 25ft/lbs at the muzzle. I can get the 6 ARC barrel right now vs likely spring next year for the 6.5 Grendel, so other than offloading the little bit of Wolf steel I bought I think the 6mm ARC will be the way to go for my use, which is mostly targets with some hunting mixed in.

If you're not dead-set on a monster barrel, Odin has this 12' 6.5 Grendel in stock...

I decided I'm going to go 6mm ARC, just need to find a bolt.

Bought the bolt from RTB, Monster 6 ARC barrel from BFT is on the way. This should be a fun build
