Hunting Energy References

.300 Win. Mag.: Retains at least 1,000 ft-lb (deer-sized energy reference) through 500 yd — the end of the listed data. Retains at least 1,500 ft-lb (elk-sized energy reference) through 500 yd — the end of the listed data.

.30-06: Retains at least 1,000 ft-lb (deer-sized energy reference) through 500 yd — the end of the listed data. Retains about 1,500 ft-lb (elk-sized energy reference) to roughly 350 yd.

A retained-energy reference only — not a shoot/don't-shoot distance. Real effective range depends on your accuracy, shot placement, bullet construction, and conditions. The ~1,000 ft-lb (deer-sized) and ~1,500 ft-lb (elk-sized) figures are commonly cited rules of thumb, not standards.
