44 mag foot pounds of energy

According to WY game and fish regulations I have to have a certain amount of foot pounds of energy (500)at 100 yards in addition to caliber restrictions etc. Any one aware of a fpe calculator on the net that I can use. I have found ones for factory loads but these are my handloads with a 240 grain Keith style bullet with no GC. The velocity is around 1100 fps but I would Chronograph it out of this particular gun before taking it to the field. My other 44 mag load the gun really likes is a 300 grain XTP with a maximum dose of H110 which easily meets the restrictions but it eats me up out of my flat top Ruger after just a few rounds.

Thanks

Does this help?

Not knowing the exact BC of the bullet, but based on 1100 FPS MV, the Lee shooter says you should have 645 ft. lbs. at the muzzle and 514 at 100 yards.

Depending upon the reloading manual you are using, there should be a trajectory and energy guide contained.

Thanks for the help. The main reason I am having problems with this is that I can not find the BC for this particular bullet. I do have the several manuals with the tables but all need the BC to correctly calculate the velocity at 100 yards and therefore the amount of engergy. You have gotten me closer however.

I used an average of 3 different 240 grain bullets that I have data for and came up with a BC of .188 which I used in the calculator for the numbers shown above. It will be within a few #'s one way or the other, certainly close enough for hunting.
