I'm looking at a ballistics chart right now, published by Big Bore Express, makers of Power Belts. According to them, the 295-grain Copper Magnum bullet has a ballistic coefficient of .168. (If you have a set of ballistic tables, such as those in the Speer reloading manual, you can use their .17 BC figures for this 295-grain bullet to check performances.) With this bullet and 100 grains of Pyrodex, muzzle velocity is 1620 FPS. Zeroed at 150 yards, it is 3.48" high at 50 yards, + 4.48" at 75 yards, + 4.31" at 100, and + 2.93" at 125 yards. 0 at 150, and -10.4" at 200 yards. Therefore, midrange misses (shooting over) at 100 are quite possible, especially if you held a little high to compensate for a drop that wasn't there!!

Keep yore powder dry!!
