There was a thread started on here fairly recently relating to springer performance with fluctuations in ambient temperature. After a brief search I was unable to find that thread so as to update it.

Airgun World dropped through the letter box this morning and, in it, there's yet another brilliant article by Jim on this very subject. A must read for anyone interested in the subject. Also looking into rings vs parachute seals and the effects of "rapid fire".

Thanks Jim.
