energy question

[huntwithme]

trying to find out how much energy i get at 200 yards when using a 26 inch barrel on a 50 cal accura mr using 100 grns 209 with a 260 grn pt gold bullet i passed on a 6x6 bull elk at 200 yards straight on shot
thanks

You need to know the velocity and BC of the bullet then plug it in to a calculator like the Berger one;

Assuming bc of a brick and BH209 posted velocity for your bullet with 100gr gets you about 1935fps at muzzle and about 1300 ftlbs at 200 yds. I would not take straight on with that energy. I believe you made good call.

Rough calc but reasonably close. Used 8,000 ft, 40 degrees, bc=~.260, the 300BT has BC of .300 so the 260 much less. I just threw in bc .260 since really means not much tossing big bullets close.

the bc is .220 and the fps is1832

Here's an interesting powder test performed by a guy using a CVA with a 26" barrel and 250gr projectiles. His 100gr loads were measured by volume….NOT weight.

Shooters have debated the merits of Blackhorn 209 vs 777 vs Goex black powder for many years. Which one should you be hunting with?

Here's some data straight from Blackhorn showing velocities and charges by volume and corresponding mass weights.

Maybe @ENCORE can chime in here as well?

I think you did the right thing. Very little margin for error with that shot.
