250 Grain Deep Curl Ballistic Charts
Here are some charts I recently worked up for the 250 grain .452 Speer Deep Curl using the Handloads.com Ballistic calculator.
There are thirteen charts for velocities from 1500 fps to 2100 fps in 50 fps increments. A 125 yard zero was used in all of them.

Muley, the gun and powder is not material to those charts. The charts work for whatever gun and powder used that produces the muzzle velocity stated.
The only "equipment" effect in the chart is the Sight Height. I used a sight height of 1.5" which is pretty much the average for a scoped rifle.

How much powder?
With 100 grains of T7 FFG and 250 grain Deep Curls, my 26" barrel Lyman Mustang gets around 1850 fps (with the chronograph 12 feet from the muzzle)

I'm not trusting of what ammo companies claim. I used to have a Chrono, but I lent it to a buddy (ex), and he shot it.
