I confess I am a hoarder.I have a hard time getting rid of anything especially guns.Could you guys give me a list of guns and rifles you used throughout the game such as when I started I used this gun /rifle then I replaced it with this one and so on.Maybe that will stop me from carrying several guns and rifles thru the whole game.

oh man it depends on the character....i guess usually hunting/riot shotgun, Lucky, modded hunting rifle and sniper rifle are my stadards. and i dunno if you know about this, probably, but its so rad it just made my dad mad:

Before GRA I had a canned answer for this question....Now I don't.

Well, there is the Riot Shotgun with Magnum buckshot. That's still the best CQB weapon in the game as I was easily stopping multiple charging Divide Deathclaws cold with that.

I agree with MD...( Did I just say that? ) It depends on your char. For my playstyle, I start out with a fully mod Varmint and the Weathered 10mm. I later drop the Varm for Ratslayer. I hold on to Ratslayer the entire game. I later trade the W 10mm for the 10mm SMG. Then I pick up the fully mod Sniper. I run with those 3 until mid game.

Mid to late game I have Chris COS Sniper, 12.7mm SMG and Ratslayer. I run with those through the end.

I keep every weapon I find, until I get Jury Rigging. Then I repair the high end ones with the cheap and get all my Implants at once.
