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 500 yards.

Product Overview

Underwood markets its Custom Competition 300-grain to competition shooters, long-range shooters and large game hunters. It is loaded with Nosler's Custom Competition bullet, a match hollow point with a boat tail, rated at a G1 BC of .800, and it leaves the muzzle at 2,700 fps. Zeroed at 100 yards, it drops about 51 inches at 500.

Compared with Hornady's Match 285-grain ELD Match, the Underwood holds up just as well in the wind: at 500 yards, a steady 10 mph wind blowing across the range pushes each about 11 inches sideways. The lighter Hornady drops a little less, about 49 inches at 500 from the same zero, and it kicks about 8 percent less in the same rifle. Compared with Barnes' Precision Match 300-grain at the same bullet weight, the Underwood starts 100 fps faster and flies a flatter path: the Barnes drops about 57 inches at 500, and the same wind pushes it about 14 inches.

Buy the Underwood if you shoot competition or long range with a 300-grain bullet and want less wind drift than Barnes' Precision Match 300-grain or Federal's 300-grain Sierra MatchKing. Pick Hornady's Match 285-grain ELD Match if you want the same wind drift with less recoil. Pick the Barnes if you want a 300-grain load with a little less recoil. Pick Hornady's Match 250-grain BTHP if recoil matters most; it kicks about 26 percent less.

Strengths
  • Higher G1 BC than Barnes' Precision Match 300-grain, .800 against .716
  • Still moving at 2,167 fps at 500 yards, 126 fps faster than Federal's 300-grain Sierra MatchKing
  • Drifts about 7 inches at 400 yards in a 10 mph crosswind, against 8 for Hornady's Match 250-grain BTHP
Limitations
  • Kicks about 5 percent more than Federal's 300-grain Sierra MatchKing in the same rifle
  • Leaves the muzzle 270 fps slower than Remington Express 250-grain Scenar Match
  • Drops about 51 inches at 500 yards from a 100-yard zero, against about 46 for Hornady's Match 250-grain BTHP
