size of pellets

Yes, they are all .22 cal ...the .218-.217-.216 is refering to the bore diameter of your rifle..
Usually with pellets, if you use the wrong diameter, there is a lot of forgiveness because of the shape of the projectile.
it can make a slight difference in accuracy and percision...not going to make a difference to the average plinker, but maybe to a benchrest or FT shooter.
The diameter of the projectile plays a bigger part when using slugs, where the fit plays a bigger role.
That is when you can "slug the rifle" ...if you wanted to do that..here is a video on the process

Thank you, very helpful. I can't find my bore Diameter of my ghost all the info that came with it just says .22 cal. I'm shooting JSB jumbo heavy 18.13gr
