So I've been pondering this question in my head since I last went back to South Africa in July.
It appears that there is a large school of thought in the UK that subscribes to sending light bullets at deer at a very high velocity whereas in many other countries the leaning is toward heavy 'n slow.
I am fully aware of the maths behind energy, but what good is high energy if very little gets imparted on the intended target?
In my mind 1900ft/lb with no exit is better than 2400ft/lb just passing through on its way to its interstellar destination.
A counter argument is of course that light 'n fast is flat, but in reality the difference between a "flat" caliber and a "loopy" caliber, within reasonable UK stalking distances and zeroed properly, is neglible.
Further, gravity is a constant whereas wind is not, so surely it is better to have something that bucks the variable better than the constant?
The floor is open to debate....
