Hello. Help needed my s410 is about 60 fps lower in cold weather. I have had all seals changed about 6 months ago but now the power is lower is this caused by the temperature drop.I have warmed the final up with a hair dryer for a few minutes and it goes up from 730fps to 780.does this mean it needs a good clean inside to Polish the internals as the grease or oil is thick due to cold weather making it thicker than normal.

Predictive spelling strikes again !!!
But we kind of get what you meant to say, Blackcat
Yes, a PCP in cold weather will significantly drop in power. No worse time for this to hit you tha when you are hunting in winter and the rifle is like a block of ice ... Once you know that it is happening, you can allow for it.
