Re: .308 max killing range
So called "expert gunwriters" always have there theory on how much energy and velocity you need to cleanly take animals. They are part of the average society and think alike. On the other hand, guys that hang around here know better then to listen to them "experts".
It doesn't take 1000ft lbs to kill deer, and it sure dont take 1500-2000 lbs to cleanly take elk.
As JWP mentioned, as long as your bullet is going fast enough to reliably expand and make it to the vitals, your going to have your animal reguardless.
I"ve seen deer shot with 55g NBT out of 22-250 and swifts at 400-450 yards where there only carrying 500ft lbs at most, and they got leveled as if they were hit with anything else. Its all about shot placement and knowing your limits.
From what I've seen and read from experienced people, deer are relatively easy to kill. Poke a hole through the vitals with anything and there going to die. I figure 500-600 lbs is plenty for deer, and 1000 ft lbs is plenty for elk. For reliable expansion, I like 1500fps of impact velocity or more. I know these numbers are quite lower then what them experts say, but I've seen plenty of deer/elk killed with those kinds of numbers with no problems.
And if you really wanna get technical about it, look how many animals died from the mighty 30-30. That cartridge dont even have 2000 ft lbs of energy at the muzzle, I doubt it. Maybe, I dont know, I dont care for the 30-30, but that dont mean it didn't kill its fair share of elk. See what I mean??
