Yes. Air density vs conditions you zeroed in. Look at how altitude density works for airplanes.Are there differences in shooting in colder weather versus hotter weather?
Air density will get you with rimfires too. Just a lot less. When I shot matches with sub sonic match ammo I would get to the club and shoot some sighters at sun up before the event, leaving them a click or two low to account for the warming day. It worked back then.IME yes.
I was shooting in sub 35F this spring & did notice significant drop off as the guns cooled.
Im going to take up rimfire shooting instead going forward
This is something I’ve been thinking a lot about because of the over the barrel storage system of my Barra 250z. The 7075 AL is thin and it’s noticeable how it affects the gun… below 50 degrees and it mostly just effects my shot count. Plus the gun just sounds different and it’s noticeable. FPS drop is minimal until freezing temps…. However I have been experimenting with a solution and have found it. One of those heated hand warmer sleeves that you see football quarter backs using. It’s open on both ends and it slides right over the barrel. It’s not great for walking around but I plan on using it to hunt coyotes from from a blind over a bait spot once the temps get cold enough… it’s not long enough to fit over the whole barrel but I just slide it down towards the regulator and plenum so any air entering the gun block will be warm…. I put hand warmers in the gun bag and keep the gun inside the house so it stays warm. It helps that I live in Utah where there air is incredibly dry too. But either way as long as you take steps to prevent condensation it shouldn’t be a problem.IME yes.
