Thanks, very nice, I shall use it.
Thanks, I'll convert your formula for grammes, from grains, as my mass data are always in grammes.The formula is simple. You just have to convert grammes to grains (plenty of converters online).
V(fps)squared X Wt(grains) / 450240
So an 80 grain projectile at 220 fps would be: 220 x 220 x 80 / 450240 = 8.59 fpe
This should make it easy for you... 1 gram = 15.4324 grainsThanks, I'll convert your formula for grammes, from grains, as my mass data are always in grammes.The formula is simple. You just have to convert grammes to grains (plenty of converters online).

Thank you, yes i did know that bit, because I used to struggle with the venerable "Grains" scene when I was shooting black powder replica revolvers, and reloading cartridges for a 44 magnum Ruger Super Blackhawk . . .This should make it easy for you... 1 gram = 15.4324 grainsThanks, I'll convert your formula for grammes, from grains, as my mass data are always in grammes.The formula is simple.
