What is the bullet drop of a .300 win mag?

The guy above is right. Remington.com has ballistic info for their respective rounds. But they are general. My .300 win mag zeroed at 200 shoots 2 1/4" low at 300, 7" low at 400, 16" low at 500. With 180 gr federal premiums. At 800 yds we are in the "feet" range. At 1000yds it something along the lines of 36 ft of holdover.

These guys gave you some good input. One problem with factory ammo is it's not consistent. Meaning you can aim for the same spot over and over again. It's not going to hit there every single shot. Meaning again your sight in will be close not on out past 100 yds. If you want consistentacy (reload). No way would I trust the Remington brand of ammo for long distance shooting, the powder loads vary to widely and the bullet weights are off sometimes 3-4 grns in most cases. The bars in your scope represent yardage, not inches. Usually in 100yd incruments. You have 6 lines for 600 yds. And like .357 said, a 20 degree base offset will be better than a standard base mount design. Also understand that a scope with 1/2 inch adjustments is for crap past 400 yds. You need a fine tuneable 1/16 to 1/8 adjustment to ever so slightly move the crosshairs.

You can use any online ballistics calculator to get the precise drop. To be honest with you, you had better try to keep it at a realistic range, like 400 to 500 yards. You must be a very good trigger man to go beyond that.
