Thread: Airgun pellets - How light is too light in spring guns ?

Supposedly, lightweight pellets don't offer enough resistance to the spring and the spring and piston slam down too fast and cause damage.

For instance, I'm using a 22 cal spring gun and typical weights for lead pellets are 14-18gr. Would 12gr be OK ? 10gr ? a cleaning wad ? Can you look at it by a corresponding maximum mechanically safe pellet muzzle velocity ?
