I was thinking of putting a heavier spring in my beeman rs2. its a .22cal. What would be the max poundage I can go to with out serious mods to contain the energy exerted from the spring. The site I found con make the springs any size from 1-400 lbs of force. 400 might be a little tiresome to cock. I think, but I might be wrong, a normal adult air rifle spring has around 150-200 pounds of force? any suggestions on how high I should take it would be great.

In this Diana 34 rebuild I used an ARH spring with slightly lower spring pressure than factory original to increase velocity. The GSI kit spring {.125"} is slightly thinner than the factory spring wire {.128"} originally in it, that takes less effort to latch the sear, while ultimately significantly improving velocity.

Properly sized well made seals and flow dynamics are usually more critical than 'peak spring pressure' is, but having a quality made spring does increase the longevity of a rebuild. I have several rifles with ARH springs, that have been shooting very well for many years . . .
