Question: Where are the "sweet spots" in velocity when tuning a.177 or .22 air rifle?
Back story: While I'm "mechanically challenged," I'm trying to tune a .177 RTI Prophet Compact. The last owner used it for shooting slugs. I'd like to use it for pellets. (JSB 8.4s would be ideal.) I've had good results by adjusting my .22 rifles to shoot around 880-890 fps. At one time I owned a .22 Vixen that shot accurately at around 700 fps. And I assume that the high power rifles must shoot accurately at velocities above 890. So--generally speaking, are there multiple sweet spots in velocity, is there only one ideal velocity when tuning a rifle, or does it vary from rifle to rifle and barrel to barrel? Thanks in advance for your help.
