I've shot in -15C weather before (that's 5 degrees F) which is cold enough for me! With wind it is miserable if a guy is just sitting and shooting. Cross country skiing, snowshoeing or about any activity that keeps you moving its different but as I get older I find sitting and shooting in the cold is not much fun. Don't mind a few shots but I've got some serious testing to do here!
Yup, got car heaters, got warm clothes, got all of it and use it. However, the older I get the less desire I have to sit on a cold bench holding a cold gun and shooting. Down to freezing it isn't too bad and even maybe to -5 C but after that... call me a wuss!
I got everything loaded and may make up some more of these Brenneke'ized slugs while I wait. I'll likely get 'er done next weekend.
