Solved from this product's advertised 1550 fps, 45gr bullet and G1 BC 0.125, with the sight 1.5" over the bore at standard conditions. Compare every zero for .22 Magnum.
How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 4" vital zone, ±2" either side of the line of sight. Dashed line: where the bullet goes subsonic. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 200 yards.

Product Overview
Winchester's Dynapoint 45-grain is a copper-plated hollow point .22 Magnum load Winchester lists for target and range use. At 45 grains nothing in the caliber is loaded heavier. It leaves the muzzle at 1,550 fps with 240 ft-lbs on a G1 BC of .125.
From a 100-yard zero it drops 8.4 inches at 150 yards, about 3 inches more than CCI's Gamepoint 40-grain jacketed soft point from the same zero. At 100 yards it is doing 1,143 fps.
If you're cross-shopping, Remington's Premier Magnum .22 WMR 40-grain pointed soft point starts 360 fps faster and drops 5.8 inches at 150 yards from a 100-yard zero. Fiocchi's Field Dynamics .22 WMR 40-grain jacketed soft point starts at that same 1,910 fps on a G1 BC of .126, within a thousandth of the Dynapoint's.
- Only CCI's Gamepoint and Fiocchi's Field Dynamics carry a higher G1 BC among the loads compared
- A copper-plated bullet, where the soft points compared leave bare lead at the nose
- A hollow nose at the caliber's heaviest bullet weight
- At 1,550 fps it starts at least 325 fps behind every 40-grain load compared
- A 10 mph crosswind moves it farther at 150 yards than any of the 40-grain soft points compared
