Re: H-1000 velocity variation/air temp value??
I don't use as it changes things on the app more than they really change, I think your better off just ignoring that feature with H1000, Retumbo, Varget, Magnum. even rl22 is more stable than that feature allows for
Here's how it works though
Powder Temp - This is an optional input and should only be entered if you also entered an MV Variation. This is the base powder temperature and should coincide with your Muzzle Velocity. So as in the example in the "MV Variation" field description above, you'd put 55deg here and 2850fps in your "Muzzle Velocity" field (or you could be 57deg here and 2855fps in Muzzle Velocity, doesn't matter). Now when you run a calculation using this ammo profile, there will be an option to enter current Powder Temp. If you were to specify say 65deg for powder temp, Shooter will automatially raise your MV to 2875fps.
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
