And that pesky butterfly off in the distance, darn things. If the op wants a FLAT trajectory a .17 is it....as long as it's a .17 HMR. that is.You have two completely different questions in your thread.
Flattest Trajectory (TM) is simply a factor of muzzle velocity, retained velocity and scope height above bore. How are you with differential calculus?
Accuracy is 100 times more involved than a function of ballistic coefficient. Pellet precession, nut, wind drift, center of pressure, center of gravity, spin rate, gyroscopic stability, shooter's ability, the fit, form and function of the gun, valve and other mechanical influences - just to name a few things that affect "accuracy."
As previously mentioned your question is pretty much not answerable as posed. Pellets from the moment they leave the barrel are rising until they reach the beginning of their apex….the length of the apex or flat portion of the flight is affected by pellet weight and speed and ballistic coefficients. A more appropriate question is to ask “what air pressure will produce the speed that is needed for a particular pellet type and weight to produce the longest possible flattest trajectory. Of course then you need to know about barrels / barrel types / twist rates / choked or not… sigh the questions only get more complicatedWHAT SIZE PROJECTILE HAS THE BEST ACCURACY AT 50YARDS.
What is "nut"?You have two completely different questions in your thread.

The one that produces the smallest groups!WHAT SIZE PROJECTILE HAS THE BEST ACCURACY AT 50YARDS.
Thanks for that!In short, there is not short answer in the world of Airguns. There is NO DEFINITIVE BEST, or any other -EST (flat-est, best-est, quiet-est).
It all depends (TM) on a multiple of factors.
Just to add to the implication here, check out the "winner's circle" where you plan to compete and see what's performing.In the N50 pellet class, the top 15 or so shoot 22 caliber.

Simple question, non- complicated answer. Assuming non-competition, .22 cal. 18.1 JSB or FX pellets are the best compromise for me . Better in the wind than .177 and less bullet drop than .25.WHAT SIZE PROJECTILE HAS THE BEST ACCURACY AT 50YARDS.
