what would everybody say is the amount of energy required at contact to pass through both lungs on a bull moose? Every bow starts out with enough, but at some point does not have the required lbs.

I would worry more about the tip used, the shot angle, and the shot placement. Put a Silver Flame on an arrow off the shelf of my longbow and I'd take a clean, broadside, 20 yard shot. If you have a compound, I'd guess with the right tip you'd be covered. I have heard a lot of talk about 60 KE being the minimum number for elk and moose - but I can tell you that a lot of these animals have been killed with far less energy. That said, my first elk was a spike. I shot it with an older bow, 650 grain arrow, three blade Muzzy, probably around 63 KE - the arrow went through the far ribs and caught by the fletching. The tip had, obviously, passed all the way through both sets of ribs. Those older Muzzy tip are not, in my opinion, the best tip for penetration. The shot was about 40 yards, broadside, down hill slightly.

my Desert Stryker x-bow, shooting a 497gr bolt, starts out with 106KE. Your thinking 50yds shouldn't be any problem. I'm shooting a 150gr bolt cutter.

I've never shot a bow with over ~93 KE, a pal of mine shoots a lot less - his moose was in that range, distance wise, in Alaska. Put the shot where it is supposed to be, with a quality, sharp, well designed tip, and I think you will have plenty of energy on the arrow to get it done. I'll have to look up the bolt cutter - not familiar with that one. I will mention though that a 50 yard shot has it's own potential issues that won't have much to do with the energy on the arrow! But I won't harp on those, we all know what we can and can not pull off. Plus, every shot is different - it is up to you to figure out the whole "shoot" or "no shoot" thingie. Most of my elk have been in the 40 to mid-40 yards, so I understand. I comment here in the xbow section not because I shoot them, I shoot longbows and a Bowtech 101st. I think mass and speed gets us to KE and momentum. After that, it is all about hitting what you shoot at with the right tip... To me, the means of launching does not matter in the least - so far as what the projectile will do once it arrives.
