It’s completely fine for elk, I have seen a few roosies that would agree, and none that wouldn’t.
One shot in particular, I took a teenager to kill her first elk, first shot was a done deal, it was standing there dazed, so I had her shoot again, almost head on… bullet entered the neck, went through the whole body, completely blew up the femur (made a mess actually) and exited… that’s surprising to me, but also confidence inspiring.
The elk I see shot with a rifle will mostly be with a creed, with some bigger cartridges mixed in, and the 7-08 is another good one for less experienced shooters.
If someone has no problem with recoil, shoot whatever you want, but heavy recoiling rounds make a lot of people really suck at shooting…. If you can introduce someone to shooting that never forms bad habits, that’s a big deal, and lighter recoiling cartridges are helpful there, and with modern bullet designs, they are also extremely effective on big critters.
Most horror stories come from poor shooting or poor projectile choices (like archery people blame broadheads or light arrows, or whatever)
I don’t rifle hunt elk, but if I did, I wouldn’t hesitate using the creed, it’s proven itself to me as a legit elk cartridge, granted about 350yds is the furthest I have seen them work on elk, but I assume their effectiveness reaches much further, I just haven’t personally seen it
