predicting reload velocity

[high country]

They're nice for load development, but at the end of the day 200 fps won't make any difference unless you need a vectronix range finder.

At 400 yards the difference between 2600 fps and 2400 fps (with a 3" high zero at 100 yds) is about 8 inches. I'd be concerned about that.

But it's a known value. If you're a holder over guy.....shoot a 338 edge, if you're a dope and twist guy.....it matters very little.

3" high introduces a lot of problems for people.....like the 175 yard slightly uphill shot.

why would any one sight in 3"high at 100   if you want to be zero at 250 then zero at 250.   Seems to me that would leave a lot of uncertainty like the up hill 175

I'm a zero at 300 yards guy... 4 inches high at 100... Most my shots are in the 300 to 500 yard range. Makes holdover easier and anything from 100 to 500 no dialing of the scope necessary an then have dope chart for set distances which cuts down on my mils to dial with a 300 yard zero. Simplifies it for me! Not meaning to jack the thread, best way I've found for reload velocity is to shoot from 100 to whatever , work backwards mathematically to find velocity.. As said math doesn't lie

I am a dial and shoot guy, "zeroed" at 100.  Actually, the dial is set to 100 most hunting situations as that is the distance I would need to take a quick shot.  Longer shots almost always give the time to laser and twist.  The nice thing about the dial with distance markers is you can "zero" your gun for any yardage for any situation of hunting without going to the range.

I spent a ton of time at the range and reloading bench, $30 on a turret sticker and now shoot anything from zero out to max range with absolute confidence.

Most shooters sight in at 100 yards because most ranges are 100 yards. There are  few 250 yard ranges although it would be advantageous to test loads at longer distances than 100.

It really comes down to how one hunts and knowing their weapon which dictates how they set it up!

  part of zero @ 100 also comes from the glass being used.  Some people have BDC glass for their caliber etc and those often call for 100yrd zero to use the holdovers built into the glass.
