is there one?

I'm finding it's something I just don't use hunting rifle is rubbish because of the shot speed, sniper/marksmen doesn't have enough power for long shots, or I've not found one I can mode up that much.

It would be nice if there was a 50 cal pistol or revolver..

Sniper rifle is probably the best option.

I wish there is a gun that its base reciever was a 50 cal so we can mod it with armor peircing or a bigger kick or what have you.....fingeres crossed for dlc.

I read in a post awhile back that a .50 heavy machine gun was supposed to be in NV.

Having a .50 BMG in anything smaller than a large anti-materiel sniper rifle or a heavy machine gun would be insane. Yeah I know, not the best game to bring that stuff up...

What's not to like about the .50 Receiver? I one-shot Mirelurk Queens by the dozen with that thing. I like that it gives the gun a different feel and that delicious sound, rather than just boosting the damage.
