Yes. You can leave your good springer cocked for hours too, with no significant losses or adverse effect. Hunters been doing it, I do it, and it's been studied...
nah, that ain't right..on a modern gas strut, the piston to seal fit is tight enough that a large molecule like nitrogen won't fit through.given the hundreds of nitro guns owned by people in this forum, if rams were failure prone it would shouted from the rafters..nitro rams that are centered and not abused with light pellets or detonation will last along time. the lack of centering that kills most rams that fail in the field isn't a ram failure it's a manufacturer failure. as are the QC related sealing failures that show up at the beginning of the life cycle. a cheap ram is a cheap ram and a cheap gun is a cheap gun that's why there are aftermarket fixes for them and places like this where the people that have those guns can find the fixes.
Cocking has gotten a lot easier on my son's Titan GP from when it was new at Christmas. I wonder if the gas ram has lost a little pressure?Don't own a chronograph, sorry.
