Ground effect on pellets ?

james.dean · Feb 17, 2016

Hi buds,
Have you ever witnessed / experienced this while shooting ??
Do you think That, because of the ground heating up quickly after a very cold night, of you're shooting close to the ground (30 cm max from the pellet to the ground during the whole flight) your groups can be altered ??
Because either I have an issue with my set up or that's what happened as I normally shoot less than a centimeter groups at 65 meters and today, at the same distance, groups were not less than 6 centimeters..
Even if heat waves didn't make the thing easier, That's just not normal...
What do you think about it?

My 100 yard range goes the length of my pond and in certain condition it has a great affect on my shots. Even my powder burners are affected up until you get into the 3300 fps rounds.

Thanks mate =)
I'm reassured to see I'm not the only one to experience groups opening in these conditions =)

Or shooting over open water. It seems like the pellet get sucked down by the surface. An illusion of course, due to the fact that plane water make you think your target is much closer, but now and then I really get the "suck down" feeling.........

If you have any sort of mirage, that makes the target appear to be in a different place than it actually is. The heat waves make a lens out of the air. Rising air current can also affect the pellet flight, as can down drafts. However, for the most part (I primarily shoot prone), I've found that being closer to the ground negates a lot of the wind issues, as the wind is slower close to the ground than it is the further from the surface.

Very good point I_Like_Irons!! I do alot of my shooting prone as well and the wind is not as prevelant close to the ground. At my home range, I had to make some adjustments because of small rolls in the terrain, I was hitting dirt before the pellet got to the target. Now that I have all that figured out, it is sometime almost unbelieveable the difference in wind deflection from the prone position to a benched or standing rested. +1 Sir!!

That's very interesting Irons and AJ. I will have to try that once the ground dries up. Its been raining like mad here lately.

I have noticed poi changes shooting over water especially wit a little wind in the picture.

Great point Nappyman!! Shooting over water can be very tricky.
