I’d lean towards the Accubond and TTSX myself but I have 0 experience with the Berger, so its my tendency to use what has worked well for me in the past. The other nailed it. Once the rifle is on paper at 100 with a good zero, I’d wanna check them all out at distance to see how they hold up. As BSA mentioned you’ll have to spend some trigger time just getting good yourself out to the extended distances.
Unlike BSA though I’d bet my average elk ranges have been in the 250 yard mark.. maybe I need to get better at tracking though..
I think you’ve got a solid plan, I’d address the trigger and make sure it’s light enough to shoot well off of a pack and get to shooting. I think you’ll find with some dedicated time it’ll work just fine for everything you mentioned.
