Can someone calculate the energy...

Permanently deleted user
for a .458 325 grain Hornady FTX bullet traveling at 2027 fps for me? I don't have any software that will do that and I cannot find a similar bullet in any of my loading manuals. Thanks!

    Thats about 3000 foot pounds. See page 81 on this pdf file.

    Handy calculators from www.handloads.com are about halfway down the right column. [8D]

    I get 2964 ft/lbs. 3000 is probably close enough. Velocity times velocity divided by a million times bullet weight times 2.22. (Velocity is in fps and bullet wt. is in grs.) Try it!

    Energy of anything is just speed times mass. Simple 9th grade math. The trick is to convert to foot/pounds which everyone uses for most comparisons. [:(]

    E=MC squared: I believe it was Albert Einstein.

    I think that is still just a theory. Mass {M} times the speed of light{C} times itself {squared} equals energy. The closest we have come to prove it is called a thermonuclear explosion.[;)]

    babun hit on the point I was making...converting all that into data we can use.

    Sounds like a 45-70 load, shoot a 350gr out of my Marlin 1895CB just a little faster. Works great on elk, shoot a 400gr Barnes SS out of my Siamese Mauser 45-70 about that fast. Keeps the elephants out of the tomato garden, and the rhinos out of the rhubarb.[:D]
