Re: Colorado elk bullet help
Irregardless how any bullet prints on paper, if it doesn't perform 100% reliabily and never fail, you shouldn't be using it for hunting. You should never have to worry about pushing a bullet to fast or to slow, wondering if the load is just right to perform. Any HUNTING bullet that causes you that kind of work, isn't worth using on paper.
Powerbelts are well and widely known for being unreliable. Bullets that are supposed to mushroom, shoot and act like a FMJ, punching nothing but a hole. Others completely explode on impact, with very little if any penetration. The internet is full of hunters with bad expierences from one end of the country to the other. Complaints of extremely poor to non-existent blood trails, with perfect hits. Just because someone may shoot them and in the past have had good luck, its only a matter of time. As mentioned above by another poster, he's had elk lost from hunters shooting the bullet and doesn't recommend them. See his reasoning?
I would highly recommend that you do some searching and just see what others have to say. Then think about this..... IF a bullet MAY perform that badly, why would I want to risk it? Use a premimum bullet and one that doesn't have so many bad reviews across the country.
