Top 2021 Colorado Leftover Tags

With Colorado hunting seasons about to kick off, many hunters have shifted squarely into hunt preparation. However, if you are like us, you may not have drawn that coveted tag yet again. So once again, HuntScore is here to help you quickly pick out the best leftover tags. Once again we have ranked leftover tags by coming through historical data and finding the gems. Some of Colorado\'s leftover tags have over a 50% success rate and go on sale Aug 3th @ 9 AM MT at CPWD\'s site here. Below is our ranking for the top 5 tags available per species, sex and manner!


If you want to stay up to date throughout the season, we suggest checking out our blog on Alerts! You'll never miss a leftover or returned tag opportunity and also be able to immediately see all tags that fit your hunting criteria.  

Methodology

Our analysis assumes the primary objective for purchasing a leftover tag is success in the field. So we aim to find the highest harvest rates for leftover hunt codes. Using the prior 3 years of harvest data, we used a recurisve match to find the best possible harvest data. What does that mean? Well the thing is, some of these leftover hunt codes haven't been available in the last 3 years. So we find the next best match by loosening up the fields we match on. First we try matching across the season, sex and manner (full match). If we don\'t find a match we drop, we drop the sex (nosex match). If we still don\'t find a match, we drop the season. You get the gist. Basically we try to match as best we can to give you an idea of what the harvest rates might be like.

About: Matt grew up running around the oaks, pines and birches in central Minnesota. He spent his youth hunting, fishing and riding bmx. For better or worse he's a restless hunter, prone to wandering the reaches of public land. Many youthful days were spent dreaming about chasing elk, deer and bear across mountain sides with a butterscotch maple Interarms 300 Weatherby from his father. 25 years later he still has the same dreams they just happen to come true every Fall and Spring.
