[@ClocktowerEchos] I'm only commenting because you said C&C welcomed. The only comment I have is that all of the firearms you've listed are chambered in a caliber with a lot of recoil (though the .357 in a lever-action wouldn't be terrible). As long as most of your cult members are larger people, this works out just fine, but if you have smaller individuals or people that aren't as familiar or well-trained (they could all be trained in each of these weapons proficiently for all I know), something with less recoil would be more effective than something with a lot of power.

If you do decide to include smaller calibers, I recommend keeping with the Remington Model 700, but selecting several chambered in .223 in addition to the .308 models. The .223 is more than capable of reaching out to distances up to 600 meters in the hands of a capable shooter, and while it has less power than the .308, well-placed shots on a human target will put them down easily.

For revolvers, I would suggest finding something in a 9mm selection. Ruger makes a small one called the LCR that can be kept in a pocket for self-defense purposes. It's hammerless, which means it won't snag on any clothing if you have to draw it in a hurry, but that also means it has a double-action only trigger, which means each pull of the trigger requires a longer, more difficult squeeze of the trigger. Taurus also makes one called the Taurus 905 that operates more similarly to your usual double/single action revolver. That you can fire in double-action, but you can also pull the hammer back for a crisp single-action pull as well, if you are able to take the time between shots to do so. 

And for lever-action rifles, you could pick up something in a .22 WMR (Henry has these too), which packs more than enough power to take down small game at medium range as well as put down a human with the appropriate shot placement within 100 meters. But as I said before, the .357 in a carbine wouldn't really be all that bad for recoil.

Ignore all of these suggestions, though, if you don't plan on any of your cult members not being comfortable withstanding the recoil of more powerful arms.
