Out of 150 coyotes taken in the last 2 years with 55 grain V-Max reloaded by a veteran who runs a commercial reloading and gun shop hear in eastern Iowa (FarrosLeadFarm.com ; check him out, great prices on ammo, firearms, etc.). I've had 3 unrecovered coyotes. They made it to deep heavy cover where I lost them. Only took a few second shots to finish the job on a few. Estimate 30 to 40% are dead and just don't know it. Run 30 to 100 yds. being lung to heart shot and then drop. I've been hunting exclusively at night now.
