The first elk hunt I was on I carried a 600 Remington 308. I felt that was power enough. But I came within 20 feet from a grizzly. It was following me. After that I carried a 338 Win Mag with 250 grain partitions or a 350 Rem Mag with 250 grain partitions - nothing smaller Last year I took a 270 with 160 grain partitions - first time with a smaller rifle since the 308 some 50+ years ago. I shot a lead cow at 350 yards and the cow dropped. So my advice is that a 270, 280, 30-06 or similar is plenty of power with proper bullets. It’s up to you if you will be in grizzly country, As for me, I’m chicken when it comes to something that might hurt me after I shoot it.
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally
