First off I just read the first two posts so if this info is no longer needed my apologies. What I am running, Savage lite weight hunter, .260 Rem, 20" barrel with the 110's. I checked them again last month. 3406 at 4500' on a Caldwell Chrony at 10' from muzzle. Not a heavy load for this rifle, I was shocked at the velocity and contacted Steve, he felt that what I had was similar to their results.. Shot a small buck up close last year, meat loss was minimal but the internal damage was shocking. Hoping for test #2 this weekend.
I run the 124's at 2900 out of a 22" barrel, with H4350, so I would think with the 110's out of a 16" barrel, you'd be in the 2900 range for speed as well.
Here's a pretty interesting article on how speed is affected by barrel length in a 6.5 Creedmoor. Honestly, if I had it to do over again, I would've gone with an 18-20" barrel as I'm supressed 99% of the time.
