Factory Ammo Data **Login To See Pics of Data
« on: September 17, 2017, 04:26:39 PM »
Hi all, I figured I would post some black and white data for a Weatherby factory loading.  Most data is stated for a 26" barrel.  This is helpful for the Vanguard shooters with 24" tubes, and of course was shot with my S2 in .257 Weatherby.  Temp was 85 and shaded. 100' ASL.  Weatherby states the MV for this factory offering is 3500FPS.  Round 1 hit 3506.  Average FPS 3482.  5 shot string.

We, the unwilling, led by the unknowing, are doing the impossible for the ungrateful. We have done so much, for so long, with so little, we are now qualified to do anything with nothing.

Pretty good results out of the 24" tube. I have found they my 257 Vanguard seems to reach very close to printed velos the few times I have run it through a chrono.
