About shooting a bow in the cold.I have and am sure many of us have shot bows in just below freezing weather.I really don't think it makes a diff.I leave the bow strung a little while before going out to hunt in the cold weather.Lots of different experiences and opinions on this.One thing though is as the winter goes on the dry air can increase the poundage of a bow a little.A couple of pounds at times and more.I think as long as the humidity does'nt constantly stay below 30% the bow should be ok.Some woods become brash quicker than others,or are'nt as elastic so to speak.
That ELB bow was not fine tuned tillering at all in my opinion.I would send it back for a refund.
