6mm ARC vs 6.5 Grendel Sanity Check

[biodsl]

With the less than grendel case capacity and limited to mag length, aren't the 109s a touch long? What kind of velocity vs barrel length?

I saw an old article on accurateshooter or something that seems relevant to this discussion... looking for it.

Old and comparing against 6br but still..

I've been playing with the 115gr RDF in my Rebby Lilja 16" 6ARC. The RDF measures at 1.342, longer than the Berger at 1.277. Getting around 1MOA at 2490fps with LeveRevolution so it can be done. I bet the Berger is a more accurate bullet though. The 105 RDFs aren't very good in my barrel. I'm going to push them closer to the lands and see what happens.

Note: At standard pressure, this 115 RDF load is supersonic at 1150 yards. It goes trans-sonic at 900 yards with 479 lb-ft of energy. From a 16" barrel.
