It's because of the lutefisk that we stick around.




Yummy; fish cured in poisonous corrosive checmicals...sounds llike my idea of a treat. I saw that stuff featured on Bizarre Foods and honestly would love to try it...I've never had food I wouldn't try at least once.

its that cold here in wisco too. if i shoot outside i get about fifteen minutes before my fingers are burning with numbness and are almost too stiff to pluck a pellet out of the tin!

about temperature though, i don't think it has much effect on springers. i zeroed my big cat when the weather was above freezing, and last time i took it into the elements it had to be about zero and she was still dead on. noticed at about 50 yards or so the pellet was dropping considerably so maybe it has an effect on velocity, with less air being drawn in

Part of the problem with 'cold'- which is not the "air" per se- but the temperature itself- parts contract. I.e. piston seals and other such things, and the more they contract the longer they will take to expand when used, and some parts (i.e. a breech seal) on a springer may not warm up quickly/much at all- meaning the extreme cold may affect output- but it's not related directly to air "pressure" because of the temperature.

If the seal was properly expanded... then the air volume would be the same. It may compress easier since it is cold already, and would heat up less. <- Possibly resulting in lowered velocities because the air will not want to expand as quickly after the piston's stroke.

maybe it's just her breaking in since we just passed the 500 shot mark, but out in this near zero weather the cat barely holds 2" groups at 25 yards and there are more than occasional fliers. one of the last times i was shooting it was from inside the house at the snow and it seemed to be holding tight like usual, but it seems the temp is actually affecting accuracy
