Nah, cold temps are fine for shooting. Heck, the barrel stays cooler and so does the Coke on the shooting table. But along with that we've had high winds ("Taku Winds" called locally) of upwards 90mph at the harbor. Less back in the Valleys but you never know until you get there.
I've been reading a lot about bad primers in factory ammo these days. More so than ever. I think that's why I use one of those roll pads to lube cases instead of sprays..... it controls more of where the lube goes.
