Good subject Badger and welcome back, the original M6 was .22 hornet and 410 shotgun, a bit more power for the center fire but can't carry a lot of ammo, and it was meant for the USAF, it only held 9 rounds of Hornet. The current .22lr version and .410, has lots of possibilities that I think compliment each other, especially if you reload, the .410 chamber will accept 45 colt, 454 casull, and you could reload these with lower pressure round ball, or expansive bullets, but sticking with the original conception, is not bad either. I also considered buying one of these many yrs ago. The use of para cord on anything, just to have it available is a good move, I use it on my knife sheaths on certain knifes and it is always good, make snares, turniquet etc, and just having cord to make shelter is good, so wrap it around everything you can and have it handy. Nice video too, it will do the job, and if you carry some super colibri aquila ammo, super quiet, but I have killed 72 squirrels in my back yard with nobody noticing, right behind the ear, and they fall out of the tree.
