hello there,

just wondering what is the best and preferred FPS you have found for Crown .22 with JSB 18.1 gr to have tight groups at 100 yards?

thanks.

 

Each gun/barrel will be a little different. Approximately 900 fps is a good starting point. Then go through and sort all your pellets for consistent weight and condition.

shoot a crap load of pellets .

Find out what your gun really likes. considering that you can have a 10 fps spread, and the human factors, just get it to the point that you are happy with the groups.

Any pellet will start to destabilize at higher FPS speeds. (It's just the limitation of their design)

But the idea is to get it up to it's maximum FPS to reduce the time in flight and give it a flatter trajectory. 

I would assume that you have a crono? So go out and have fun!
Good Luck!  Be safe!

Have a Great Day!
