After going into the topps casino for the first time, when they took my guns they also took boone's sniper rifle naturally. Unfortunately now I can't get it back to him since they gave it to me and it doesn't show up to transfer inventory. I also tried going in without him, but they ended up putting it in my inventory anyway. Its useless now since i don't know what its supposed to take for ammo. What's my best bet?

Also, why couldn't it just be made to put all my guns back where they were including hot keys? This would solve the issue.
