Punch it into the ballistics calculator I posted

Here is data from Pigs calculator out to 500 yards. Sight in for 100 yards, and if I read the data correctly then it has 7" of drop at 200 yards, 25.9" at 300, 61.3" at 400. With 1117 ft-lbs/s of energy at 100 yards it should be good fo most Florida game aside from Bear and Gators, neither of which I have a desire to go shoot.

Great for 100 yards or less with probably a max of 200 yards.

I was trying to be generous and gave it a ~250 yard deer round.

Well with a 200yard zero the drop is about 15" at 300 with the same energy.

My concern is the energy won't be enough.

If the barrel length is 20 inches, then I agree that a max of 250 yards is reasonable.

According to Sierra Infinity, the Federal Fusion 7.62X39 ammo at a starting velocity of 2350 fps drops to 1656 fps and 750 ft lb of energy at 250 yards. While 1000 ft lbs is preferred, the bullets should be soft enough to open up at the reduced velocity to do adequate damage.
