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 8" vital zone, ±4" either side of the line of sight. 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 400 yards.

Product Overview
Winchester's Super-X 300-grain JHP is a jacketed hollow point .45-70 load made for deer. Winchester's bullet has an open nose over a lead core inside a copper jacket, the oldest and simplest way to build a .45-70 hunting bullet. It leaves the muzzle at 1,880 fps with 2,355 ft-lbs and has a G1 BC of .283.
Zeroed at 100 yards, it drops 11.6 inches at 200 and 40.7 inches at 300. From a 200-yard zero it drops 23.3 inches at 300, and it reaches 200 yards with 1,333 ft-lbs.
If you're cross-shopping, Grizzly's 300-grain JHP shares the bullet weight and the open-nosed jacketed build but starts 380 fps slower with 856 ft-lbs less at the muzzle. The two do not share a hold at any distance.
- Still moving at 1,415 fps at 200 yards, the most of any 300-grain .45-70 load
- Holds 1,776 ft-lbs at 100 yards
- Kicks less than any .45-70 load over 300 grains
- Kicks about 21 percent harder than Grizzly's 300-grain JHP in the same rifle
- Winchester names deer for it and nothing larger
- A lead core, so it cannot be used where lead-free ammunition is required
