Its output was a ongoing velocity vs. time plot rather then velocity vs. distance. It confirmed one thing Harold Vaughn had shown with a magnetometer rig in his e book, Rifle Accuracy Points, about fifteen a long time prior to him, and that's that more than the first couple of calibers of bullet journey further than the muzzle, muzzle blast more accelerates the bullet a little.

And I agree with The purpose on Varget becoming more stable at lower temperatures. An additional reader produced a comment about that, and honestly I hadn’t created Be aware of that before you decide to fellas mentioned some thing over it.

It looks as if there might be sound introduced in the data from other things staying released, but I’d have an interest to listen to your results if you try it the other way.

You need to do understand that when you change the temperature on the bullet by that Intense of the mount which the physical measurement from the bullet actually adjustments.

To even get fairly correct effects of the concept the particular rifle would have to be heated and cooled concurrently as the bullets.

I have an interestng BDC turret wrap design and style from my scandinavian close friends and it spans from -20 to +20 for Lapua military services sniper ammo any variation is staggering as you get earlier 500m or so.m

The purpose of the discipline take a look at was to quantify the temperature stability of the popular Hodgdon H4350 and Varget powders and Look at Individuals to IMR’s new Enduron line of powders.
