Does the 1 1/2 (or 2) rule still apply today?
Does anyone, other than myself, use it when considering the animal(s) they are hunting?
Perhaps some of the older generation on here, and a few nostalgic "youngsters", may have heard of the 1 1/2 (or 2) rule debate for hunting.
Some insist on using 1 1/2, others insist on using 2.
What is the 1 1/2 or 2 rule?
An arbitrary factor by which to select the proper caliber and ammunition for a hunt.
Formula: (I'll use whitetail deer)
Average animal weight x 1 1/2 (or 2) = recommended caliber
250 pound animal x 1.5 = 375 foot pounds of energy (penetration/"knock down")
OR
250 pound animal x 2 = 500 foot pounds of energy
The amount of energy required at a maximum given distance.
Hunter selects 500 yards as his/her maximum range: There by rule; the weapon of choice should have a minimum 375 (or 500) foot pounds of energy to ethically and humanely kill the animal (deer) at 500 yards.
Note: those who debate preferring the factor 2, also consider other large/dangerous game that could be encountered, such as elk, moose and/or black, grizzly /brown bear.
