    Calculating muzzle speed from bullet drop without a chronograph

    I'm looking it over and I think I need to look it over more. Thanks for taking the time... I may have another question or few... This seems to go backward. I want to determine initial velocity with distance, drop, gravity, and BC... because I have to assume the initial velocity is unknown. But...

    Calculating muzzle speed from bullet drop without a chronograph

    it should be the drop in feet, not inches... so it is 1.5 feet / 18 inches! See the redone calculations. 3400 fps would be way high for a springer pellet rifle.

    Calculating muzzle speed from bullet drop without a chronograph

    hahaha... oops. thanks. that changes the calculations quite a bit! So say you were shooting at 100 yards. You have to convert to feet... 300 feet We know G is 32.15 If the pellet dropped 1.5 feet V = 300 * (32.15 / 2 * 1.5) ^ 1/2 V = 982 fps The variation is about 3.5 feet for 600 to 1000...

    Calculating muzzle speed from bullet drop without a chronograph

    Forgive my naivety. I used to know math, but have sort-a fallen off the bicycle some 30 years ago. I hope I don't go all ballistically ignorant. I have a problem trying to calculate muzzle velocity for pellet rifles. Specifically, I assume there is a way to do it without a chronograph and come...
