Hello Guys,
Im all sorts of confused.
I have chronographed my rifle on 4 different occasions. The rifle is a Savage 110 chambered in 7mm Weatherby Mag. I am shooting a 154gr Hornady SST over 69.0 grains of powder and igniting them with Federal Magnum Rifle primers.
The gun is very accurate. I have been consistently getting .5MOA accuracy out of this rifle.
My chronograph is a Competition Electronics Pro-Chrono. It seems to be very consistant. I usually chrono more than one rifle when I set it up, and I have not had trouble with it on any other rifle. This rifle, and this rifle only, is giving me wild chrono readings.
See below:
The rifle seems to be throwing different velocities with no rhyme or reason.
I changed the scale today to see if it will make a difference. Any other variables I should try to track? I wanna get to the bottom of this...
