Anybody know the drop on a 300 Winchester Mag?

1000 yards info would be nice.

Federal Gold 190 gr. at 2900 fps.

I found one table on the internet that showed what the drop was from 600 to 1000 yards, but that does not help.

Thanks all.

You need to know the ballistic coefficient of the bullet that Federal is using in that load in order to plug it into a table.

Sure it does, that assumes a 600 yrd zero.
If it's loaded with a a Sierra
HPBTMK @ 2900 fps it will drop 338.57",,with a 600yrd zero, 175.08"

Thanks much Cardinal -- that link is now on my Favoites.

By the way, the BC on the 190 gr. MatchKing is .533.

That extra .033 of BC in the equation adds up to 10 inches of drop at 1000.
