Google JBM Ballisitics calculator, & enter your cal, bullet weight, b.c., muzzle velocity, altitude, temp, & zero range.
To keep it simple, remember 3 basic criteria
1800 fps min (for most, not all) bullets to properly expand
1500 ft lbs energy min recommended for Elk size critters
1100-1000 ft lbs energy min recommended for Deer size critters
Remember these are Basic, Generally accepted numbers. They are not absolute nesicities. Bullet choice for intended purpose/critter, is a crucial factor.
(I love my 180 Accubonds @3100 MV out to 750-850yds from my 300WSM)! A 200gr Accubond @ 2900 fps MV will getcha closer to 1k with less wind drift, more velocity, & more energy
JBM is free. It's really a handy tool for giving you a good idea of energy, velocity, & drop.
It's not perfect, but it'll getcha real close.
You'll have to record your own actual velocities & drops in the field to perfect your data, but JBM will get you real real close out to 1k or so on steel, or paper.
