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

I usually like my springers around 890-950 range and choose the pellet weight depending on that and accuracy. If gun goes beyond 950, I use a higher weight pellet (Provided its accurate)

Usually if a pellet is too light the sound signature of the rifle is more like crack, recoil is harsh and overall harmonics go for a toss. You can feel it. My Diana52 .177 was going as high as 979 on a 7.87grain JSB and I could feel it. Started using 8.44 grain JSB and I could feel difference in the shooting cycle. It is more subdued.

Not sure if this answers your question, basically you have to experiment a bit with different pellets and employ a chronograph.

My 2 cents

In looking at increasing power for
a 1322 I just got, an increase of port size increases air flow on discharge helping to increase power, so I'm assuming a smaller port will increase resistance. probly be something a pcp shooter could tell you. they deal with ports and valves as standard.

It's a spring gun and I'm worried about breaking the spring, piston etc if the pellet is too light and its half way like dry firing it.

As a general rule, with spring guns i would stay away from alloy or leadfree pellets. They are usually too light. For the very powerfull springers i would avoid the lighter lead pellets lke Express and RS pellets by JSB or other similarly light ones. For the really weak springers i would avoid the heaviest pellets. Otherwise don't worry too much.
