For Elk
you should use a Core bonded bullet, Sold copper bullet, Heat treated Lead with gas check or a Sold Brass bullet.

Hornady 300gr xtp may not work people tell me that the jacket comes off too easy. Barnes makes 225gr sold copper bullet that does good

on ammo Cor Bon makes a great line for the 44mag and Grizzly has a great line of boned core and sold brass "called the PUNCH" 44 mag ammo
