Can you explain how you came up with this, I thought the drop of a 22 bullet at 300 yards was around 10 feet, standard 40 gr traveling around 1050 to 1070 fps.

I went in to my ballistics app and adjusted the zero distance to be 350 yards, which is what it is when I have adjusted the elevation on my scope. Wolf MT shows 77.1 " high at 200 yards and SK Biathlon shows 69.3 " high.

With a 50 yard zero, the drop is around 10 feet or more, but because I adjust the scope and point the muzzle more up in the air the bullet rises above the line of sight.

I realize trajectory isn't nice and even like this, but if your mid point is 72" high to hit zero at 300 yards, you drop 72" in 150 yards or 5400 inches. 0.013" drop every inch, .143 inches in the 11 inches of gel, if it didn't deflect, would still look pretty flat.

Even a drop of 3 feet in the last hundred yards is only a one percent drop, just a tad over a degree. Plus the nose of the bullet isnít pointing down, gravity is pulling it down while it flies straight and level. When it enters a denser medium to travel through, the drop will be even less than through air. So the path through a ballistics gel should be pretty much level.
