7mm Rem mag for elk.
I used to use 175 gr. Nosler Partitions. 9 elk: average 3 bullets and 140 yards.
I've switched to Berger 180 gr. VLD hunters. 7 elk: average 1 bullet and 0 yards.
Shot ranges averaged ~250 yards.
Some comments from above:
"you need 1800 fps for expansion." True - with a muzzle velocity of 1850, the berger at 6000' elevation has 1845 fps at 1000 yards. 2200 fps at 600 yards, 2000 fps at 800 yards.
"I say aim for the shoulder." If this is your style then don't use Bergers. They will not penetrate through. Each of the 16 elk above were shot in the heart/lung region. Why waste meat?
"Larger that elk I'd use a more solid bullet." True again. My 44 Mag on my hip for grizzlies was not sporting Bergers. It had handloads with Hunters Supply 44 Cal 300gr FP Hard Cast Bullets, Lead Flat Nose.
I was looking to break bone and penetrate everything, not splatter at the first sign of real resistance.
"Bergers require a Twist rate that most rifles don't have." Yes and no. Berger has a stability calculator on its website. For my hunting conditions (elevation, temperature, air density) the 180 Berger is stable for almost all conditions out of my standard Remington 700 (9.25 rate of twist) and my Kimber Mountain Ascent (9.5 rate of twist). The Berger 195 VLD is not stable for some of my conditions, so I choose not to load it (sticking with the 180 VLD's).
