RE: Do you really your rifles trajectory?
One thing that seems to floor most people...
You drop a bullet and shoot one, both hit the ground at the same time!
Course that's if the ground was perfectly flat etc...but the physics are all there.
All bullets drop, and whether its a 300wby or a 375H&H, there isn't a huge difference, sure a .257wby vs. a 45-70 is quite different.
But dead on at 200yds, I find most bullets, drop close to 40" at 500yds, sure +/-, so whether its 45" or 38" or 50", it's never, 5" at 500yds vs 50".
I've never been too into that zero range of my bullet, I like to know where my bullet will be at a certain yardage.
