well, just returned from 3rd season Colorado, we went there armed with 2 bull tags and 2 leftover cow tags, the weather of course sucked, full moon , 30 in the am and 60 the rest of the day with bright sunshine, we were hunting low on private land that held no elk, but, elk transitioned thru the ranch heading back to BLM daily hopefully. The season started off well, we killed a cow opening morning but didn't see any other elk that day,next day rain and no elk, Monday I was lucky enough to kill a beautiful young but very large cow, incidentally, the first cow was shot with 300 win mag 180 gr noslers out of a Christiansen arms long distance shooter, it took 3 rounds to put her on the ground at about 140 yds, first 2 were thru both lungs and she didn't act like she was even hit, the 3rd broke her shoulder and she dropped, my cow shot with my .338 win mag at the same distance using 225 gr Barnes x and she literally went legs up in the air. So now to the ethics situation, we had a blind set up overlooking a 500 yd meadow that we were able to use only 200 yds of our private and BLM land, the rest was a neighbors and off limits. Unfortunately there is an oil company gravel road that cuts thru the far edge of the property, fast forward to weds evening around 5:00 pm, now, shooting is over at 5:33 pm, with 30 min of shooting light left a herd comes out of the trees and starts grazing toward us, the wind is in our favor , leading the pack are 2 6x6s followed by a 5x5 a 5x4 2 spikes and about 8 cows and calves, they cross the road onto our side and they stand there grazing, we could have made these shots but I got greedy, choosing to wait until they were closer , suddenly a pickup come up the rd and the herd splits, the truck stops in the middle of the herd and hangs out for 5 mins but doesn't shoot, finally the turn around and go away, the herd rejoins together and heads back towards us grazing slowly, another pickup comes from the other way and turns sideways in the road watching the elk,no shots fired, finally the truck leaves and the herd heads our way, we are running out of light but we still have 10 minutes for them to reach us, finally, the herd is 70 yds away standing Broadside all in a row, guns up on sticks ready to count to 3 and fire together and I look at my watch.......its 5:38 , 5 minutes past shooting time.....end of story, we let them walk. One of the hardest decisions I've ever had to make. There would have been no mistake about who shot if a warden was near and Colorado has the Sampson law that kicks your butt if you poach, it actually made me physically ill to know that we had passed up a 200 yard sure shot only to have them in our pocket and couldn't shoot!
