Personally, I care a lot less about trajectory (in most cases) than I do recoil.
Especially since I use a laser range finder at any distance that matters.
Things I shoot aren't hard to kill and I'd much rather have a gun that's fun to shoot than use one that would kill elephants when I'm only shooting deer.
Most of the time, differences between cartridges are irrelevant. If the shooter is up to the task, they're up to the task, and if they're not, whatever difference there is between a 270 and 30-06, or 243 and 300 WinMag, isn't going to suddenly make up for the shooter's inadequacies.
Skill matters. Power almost never does.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
