Re: Reloader 17 temp v velocity change
I cannot recommend any other brand of primer as I have never run any real tests comparing different primers in cold temps, but I will say that CCIs not working in the cold is something you'll hear about every now and then, I wouldn't call it common but it does happen.
You could just keep your ammo in a coat pocket. My problem occurred after the ammo box was sitting in the snow with 19F air temp.
"Out of range" is a theoretical concept as far as I'm concerned. Send it!
