I'm not familiar with the marlin 308MX, but marlin makes a great lever action. I would give a word of caution if you are planning on using hornady leverevolution ammo. On at least some marlins, the leverevolution ammo can jam in the magazine tube, leaving you standing there holding an expensive club. That is decidedly not fun when you have a 280 lb boar coming after you. Been there, done that, not fun.

About any centerfire rifle of .243 caliber or above will do the job on hogs if you do your part. But I would suggest that you never use a varmit bullet in any caliber on hogs. That, in my opinion, is a recipe for disaster.

As regard the see thru scope mounts, in my opinion they are not the best of both worlds, they are the worst of both worlds. I would suggest either a good peep, or a low power scope, I have a couple of the nikon 2X8's that work very well. Whichever you get, practice with it untill you are good with it.
