I'm new to the AG world. So I purchased the FX Crown .25, air compressor, SCBA tank, quality optics, rings, etc. I've only shot the JSB King Diabolo since that's what the Crown was set for. Once I got the gun, I performed the harmonic tuning to get the best accuracy out of the JSB's. Now, to my question. All these different pellets, hollow points, pointed, armor piercing, etc...have different characteristics, yes?! I'll assume that if I change over to another line, then I'll be back to harmonic tuning to that particular pellet. Is there's any real advantage to the other pellets? I'll pick off the occasional squirrel during season because I do enjoy eating them and the JSB's have definitely impressed me with the ability to drop them dead. Most of what I do, recently, is sit in the back yard and pick off the berries on my Bradford Pear trees and Walnuts. Occasionally, I'll smear some cow manure on a 2x12 and splatter the green doodoo flies. I've watched numerous YouTube vids where they test different pellets in Ballistics gel or a block of clay, but they don't mention accuracy. I'm more into accuracy than how big a hole the pellet leaves. For those who've tread the waters, chime right on in.....
