6Dasher seems fast for load?

[Southern Custom]

So I’m developing my first 6Dasher load on a proof barrel. Using Berger 108 hybrid target bullets, over 31.5grs of VARGET with Apha brass I’m seeing around 2900fps. I’m not complaining because it’s printing 1 hole 5 shot groups around .3 MOA.
My question is, is this speed unusual? Most everything I see from this combo is around 2850. That’s what my barrel shot for the first 100 rounds before speeding up to 2900. Just curious.

Im loading 108eld and 106 tap in alpha with 30.5 of varget and cci 450's i average 2750 but this barrel has 1600 rounds and all my brass has at least 8 firings on it.
I do know my lot of varget is slower then my buddies lot of varget. He loads the exact same and gets 2820-2840 average.

Not exactly. I’m running my new barrel at 31.2 grains of Varget at 2850. May just have a fast lot of Varget and speedy barrel.
