Hey everyone, Im a long time deer/elk/duck hunter and I blast coyotes when they get to close to my cows. Im in southwest Washington and I frankly cant bring myself to chase these decimated elk numbers anymore. Coming onto a herd and seeing each and every one of them limping on one good leg and having nothing on them but their skin and fur. Just hurts my soul. So ive made the decision to switch my efforts to hunting the predators. Hopefully helping out the elk and deer along the way. My question is, since I cant use bait or hounds. Spot and stalk or calling seems to be my options. What is everyones opinion on a E caller that can put me somewhat away from the target while also not costing a arm and a leg. My second question is rifle related. I have a 300. win mag I use for big game. It does some damage to a deer. Im wanting to go after coyotes, bobcats, cougar, and black bear. What is a caliber you guys would suggest that can drop all of those without destroying the hide on a cat or bear in case I choose to get one taxidermized? Thank you all for your time!
