Im trying to develop a trajectory chart for my AR-15 zeroed at 75, 100, 150, & 200yds. And then I thought, surely, somewhere, someone had already done that.

Im not going to specify a particular brand or ball weight, since I use several. Im simply looking for a chart of "basic" trajectory, with rise and fall.

Does anyone know a URL I can go to?

Thanks, that gives 'generic' numbers for 250 and 200 yds. It it reasonable to presume I can extrapolate the numbers for 75 and 100 yds from the difference between 150 and 200 yds, or would the angle of climb be too different at that close range.

Hi, Declan:
Use these calculators instead of extrapolating.

This is Beartooth's link to the JBM advanced online calculator.

I like Norma's; choose english and ballistic (does metrics too, if that's your flavor).
