As long as you don't have a gun set up for 400 FPS you'll be perfectly fine, high end stock guns are all sub 350, and most cheaper guns, once downgraded to 350 will have no issues. Batteries die ALLOT quicker however. Carry extras close to your body to keep them warm. And as stated, GBBs are fairly useless.
EDIT: after seeing drakes post i must add one more thing.... AVOID V2 MECHBOXES for the winter. V3/6/7/8 at minimum or spring shotties/BA rifles
