I have hunted it in september and been there throughout the winter months, Magote Ridge will hold alot of elk as well as fifteen springs area. They will still be rutting but probably call shy by then so just listen for them at night and find fresh sign during the day. Stay away from roads and easy access points as others will hunt before you do. Get a Carson NF map, and have good mud tires cause it will rain or snow for sure.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
