My 14 year old son took his first Moose yesterday. 450 Bushmaster at 100-125 yards, Factory ammo loaded with the 250 Hornady FTX bullet that goes 2100fps out of his Ranch Rifle. We can reload them hotter but hard to improve on the accuracy. The bullet hit behind the foreleg and angled forward to stop in front of the far shoulder. The moose stood for about 5 seconds then fell and couldn't get up again. Retained weight of the bullet 213.1 grains! Pretty great rig! Nice combination of low recoil and good hitting power. I was worried that the 250 grain bullet was too light for diameter but this Hornady FTX seems to think it's a premium bullet.
