Re: Confused on 7mm bullets for elk
I'd use the 160g AB if it was me. I've played with both out of my 7 RM and they are both excellent bullets. I have found the Bergers to be VERY fragile and thus not really my type of bullet for elk hunting. I like to have 2 holes at any distance/angle, Bergers are hard pressed to do that at closer normal hunting ranges.
If your elk is broadside then I wouldn't hesitate to use either bullet.
I used the 168g and 180g vld on deer and wasn't very impressed on 2 of the 3 shot. They did die, however bullet performance was not ideal.
Shot 2 deer with the 168g. The first was behind the shoulder about 200 or so yards. Bullet performance was great on that deer. Bullet exited leaving about 2" hole and a blood trail that was a foot wide. 2nd deer was shot at 600 yards in the shoulder. Deer dropped but was not dead. Moving its head around and what not. I put another one in its neck and that killed it. Upon skinning/gutting, neither bullet exited and this was at 600 yards.
Next year I used the 180g vld thinking it would give better penetration and less expansion. Anyways, ended up shooting a buck about 100 yards in the shoulder and he just stood there. Put another one behind his shoulder and he still stood there. Few seconds later he tipped over. Both bullets exited, but they acted like FMJ's. pinsize exit holes and not a lot of internal damage.
I wont be using Bergers anymore, and especially not on a large bodied elk. If they aren't performaning great on deer, they aren't going to do any better on elk.
I'd shoot whichever is most accurate in your rifle and learn to pick your shots if the Berger is the one you decide to stick with.
Just my experience with them.
