Don't want to start a cartridge argument on here, but maybe I kind of do.**
Seriously. Where do we all stand on the ballistics argument of a hunting round. Do you care more about the diameter of the round, weight, the energy at impact, velocity, or some combination. For example.
Assuming accuracy and cost are the same, with factory ammo of a good hunting bullet which of the 2 below is a more powerful hunting round for deer at 300 yards in your opinion. (This is from Sportsman's Warehouse website, was just an easy place to pull data for the examples.)
.308 Winchester 165 grain @ 300 yards 2116 ft/s velocity and 1640 ft-lbs energy @ impact
or
.270 WSM 145 grain @ 300 yards 2575 ft/s velocity and 2136 ft-lbs energy @ impact
So the debate is what is going to have better killing power in case you hit a shoulder or something. Do we want a heavier bullet with a bigger diameter or faster bullet with more energy at impact. Of course you have to have a bullet that expands properly to take advantage of either.
I guess I have always thought the bigger caliber was more critical and never really questioned it, but over the last few years reading and learning the greater energy actually makes more sense now. I read somewhere in a perfect world you want a bullet that expands upon impact and goes all the way to the skin on the other side of the game without punching through the hide to make sure all of the energy is transferred into target. Energy is wasted if we get a through and through.
Anyhow, if you go with the the 1000 ft-lbs of energy guideline to ethically take white tail, both of these options are good at 300 yards, but if you take out to 500 yards the .308 is barely making it past 1000 ft-lbs and the .270 WSM still above the 1640 ft-lbs the .308 has at 300 yards.
I guess count me in on team trust the scie.... err better say physics and give me the .270 WSM for the win on power. What about the rest of you knuckleheads?
