How Much Does Rain Affect Trajectory?

But...how many jigawatts is that?

 

Inside of the hooded aperture on an M1 or M14 match rear sight whose aperture is shaded? I don't think so.

What about the shaded side of the front sight making the visual horizontal center appear right from where it really is?

 

WOW!!

 

I believe water does not compress at all.

 

I have only shot in the rain when I had to. So yes, I have shot many times in 1000 yd. matches, in the rain and actually done quite good most under 7in. groups. I think that is mainly due to wind died down. Would the groups I shot in the rain been better with no rain? I have no idea. Maybe the wet targets make the paper / groups shrink?

 

This is how I actually feel.

 

Water can compress a little bit if there's enough pressure. Glacier ice is about 8% denser than regular ice. A cube of glacier ice in a full to the brim glass of tap water will expand enough to push water up then over the edge.

From "https://www.quora.com/Is-iceberg-ice-more-dense-or-less-dense-than-normal-ice".....

"Since icebergs calved from glaciers, their ice density is roughly 0.9 g/cm^3. (The theoretical limit for pure ice is 0.917 g/cm^3.) Not taken into account that icebergs may sometimes contain larger cavities, or some areas with less dense ice, which may make the overall structure lighter.

The “normal” ice cubes you may have in your coke or your whiskey (if you like that) are lighter than glacier ice, because they contain lots of microscopic air bubbles. That’s also the reason why this ice is white (air bubbles scatter light), whereas glacier ice is blueish. I haven’t measured it, but I would estimate that “normal” ice might lie around 0.8 g/cm^3"

 

This is off topic but the “light rule” is very old - before they made shaded sights. The rear being closer to your eyes had the most effect on your aim.

 

Glacier ice is by in large a large precentage of air. Glacier ice at the bottom has been compressed and is clear as compared to the surface ice because the air has been completely compressed out.
However, water I'd H2O, and does compress very slightly because of the oxygen in it. That is why hydraulics use oils which ate void of gases.

 

I thought it is blue because of hardly any air in it. Like my article above says.

 

Must be why a bottle of Glacier Water cost so much...

 

How did you know what we had for dinner?

 

Yes it appears blue but it is a refraction of light through the thick ice. Reduce it's thickness and in fact it is clear.

 

Just shoot a 6.5 Creedmoor. I hear they will shoot between the drops.

 

No the drops get the hell outta the way cuz the know thier fixing to get vaporized.

 

I disagree.

It can appear clear because there's less distance between the two ice-air junctions. Just like stacking 10 light blue camera filters next to one. Views through the stack is more blue than the single lens. There's a limit our eyes have discriminating light intensity for each color (frequency).

 

If you google it you will see many posts regarding this affect. I know it seems weird, but it is the light refraction or scattering of the light and the blue seems to come out. But it is clear.

 

That's a property of water's varying density due to temperature, (Water is most dense at 39ºf/ 4ºc. Above, or below that temperature it expands to a lesser density.), and the composition of the ice (air bubbles, etc).

Unlike a blue filter lens, water is clear. Any assumed color is from impurities, or more likely the reflection of the atmosphere/ sky.

 

Ohhhh, so now you're gonna' tell us the sky is blue???

((insert shitstirring emoticon here 'cept i don't know how))

 

In my experience, rain had no measurable effect on the bullet. Rain's affect is on the shooter. When you are cold, wet and miserable, it makes it harder to focus on breaking that perfect shot. It pays to practice, and not always practicing just when the weather is nice and agreeable. Get out there and shoot when it's cold, windy, raining.
