Given that Colorado elk hunters are successful on average only about 25% of the time, no shots fired and ammo cost of $0.00 is probably a common story.
Probably not. Even the most numb-nutted nimrod will fire a few "sighters" before the season.
But I do agree that the cost of bullets argument only applies to practice, not the actual hunt.
I walk too many damm miles between elk to hunt with a varmint bullet.
I walk too many damn miles to use anything other than the bullet I want to shoot. Most often it's a .50 caliber muzzleloader bullet that many will tell you (on the internet) is no good for elk.
