Hornady says the bullet is good for deer and elk with a muzzle velocity range of 2000-3100fps. That makes me think that an impact velocity of 2400fps wouldn’t be out of the realm of reason for this bullet. I may try them out of my 30-40 krag at about 2000-2100fps.
My son shot a large bodied buck through the thickest part of the shoulder with a hornady 30 caliber 150gr interlock with an impact velocity approximately 2600fps. The bullet went through the shoulder bone and left about an inch sized exit hole in front of the opposing shoulder. That’s the kind of performance I’m used to out of standard cup and core bullet.
