Flattest Shooting Air Rifle you have ?
I am curious on say your long distance shooting and what your flattest shooting round in caliber, distance, speed and Bc ?

So hypothetical if you had a zero of 50, 75 or 100, what would your drop be at say 125, 150, 175, 200 in inches or feet? What if you are off 2 yards with your estimate ?
Trying to compare my numbers with you other long distance shooters.....

Thanks again,

Thanks Jay

My flattest shooting airgun (over long distance):
caliber = 7mm
farthest distance = 500m
muzzle velocity = 1052fps
BC (RA4) = 0.220

You can put that information in a ballistic app (such as Strelok, ChairGun, etc) and get all of the data that you are looking for.

Zero distance does not affect absolute drop. Zero distance will affect the additional compensation needed.

Strelok is almost spot on at all distances. Here is what it gives me:

Absolute drop (at sea level):
50yds - 4.0”
75yds - 9.2”
100yds - 16.6”
125yds - 26.3”
150yds - 38.3”
175yds - 52.8”
200yds - 69.4”

If distance is off by 2yds at 100yds, that’s about 0.7” of drop.

If distance is off by 2yds at 200yds, that’s about 1.5” of drop.

Great numbers thank you. Sadly even is great as your rifle is ... Wow look at the drop from 100 to 150 yards pretty crazy right ?

Here's a couple of ballistic charts from my Strelok Pro of a .357 Slayer with a 10 fps speed difference going between 935 fps to 925 fps over four shots, showing a 40 yard zero. The last chart is of the speed at 900 fps. I have the bc calculated between .162 and .165 in the app. The impact at longer ranges is significantly larger with a 25-35 fps speed difference, so knowing the gun and it's shot cycle can be critical to your group size.

You’d be severely hardpressed to find a better or “flatter” shooter than what Scott (The Real Airgun Scientist) has built with this rig.

Its funny how it doesn’t make a huge difference large cal or small so long as the speed is between 900-1000 and bc below 1 @ 100 yds there are not huge differences in drop. You can go from about 9” to about 17” and thats with an under 20 fpe 177. My 25 m3 shooting 34 gr nsa @ 950 bc .114 drops 8.4 @ 100
