Use the amulet.

Standing up you take the amulet in hand and concentrate on activating it. A mist seems to encase you slowly till finally you can't see anything, then it dissipates. Looking around you can see you are clearly not on earth. This must be one of those other planes she talked about. Walking toward you is a 7' gray granite like skinned hulking humanoid creature with a mouth full of pointed teeth over an inch long. It is both hairless and naked, yet while looking clearly male, it is apparently sexless as you don't even see an opening let alone some sort of cock. It's red eyes glow deeply as it looks you over and licks it's lips. But to your surprise it simply walks passed you, pulls open a heavy metal door, and into a shop with a sign that looks like a suit of armor. The dry heat of the air assails your lungs as well, but your ring keeps you comfortable. There isn't a sun visible but the air glows a reddish hue, the walls of all of the buildings seems to be stark black and gray iron. The road below similarly is iron but only a foot or so on the sides of the road are solid, the rest of the road appears to be a grating of interconnected crossed iron bars, from below you can hear the soft wailing and suffering of some poor tortured souls baking in hell. “Oh fuck I'm in hell.” Is all you can say. Instantly leaving seems to be the only thing you should be doing right now. Your eyes dart right and left and you spot several signs on the sides of buildings that would indicate they are also shops, the one you are standing next to is called “Sean's armaments.” And a drawing you are pretty sure is a lever action rifle. “Oh, so this is the easy access to more ammo.” You say with a little grin, shaking your head. Looking at the amulet you are sure it can take you back to, the prime, you think she called it, but not till tomorrow. It seems it is a once a day powered item. “Might as well go in.” You add as you pull the door open.

The shopkeeper is standing behind a glass case full of what looks like 2 revolvers, a muzzle loaded pistol, and one large one small pair of semi-auto pistols. The man behind the case seems to be human with short neat black hair and a short neat beard. He is dressed in a simple white shirt, pants, and a black work apron over it all. “What can I help you with miss?” He asks with a welcoming grin.

“Hi do you have .45 acp, and 12 gauge bullets?”

He smiles. “Excellent choices, yes of course. I must say that shotgun of yours is a masterpiece, can I see it?”

“Certainly.” You say with a grin and hand him the shotgun, opening the action first to show him it is empty.

He looks it all over, even taking it down as if to clean it. Finally saying, “Oh I simply must have it. Is there any way I could get you to sell or trade?”

“I wasn't really looking to sell. I don't know, what is your offer?”

“None of this junk.” He laughs pointing at his display. He then locks the door and puts up the closed, back soon, sign. “Follow me, I'm sure I have something in my safe.” You follow him back into the workshop behind the next door. It is sort of a cool display of organized chaos. “Ok, how about any of these three, plus ammo trade even bullet for bullet.” He then shows you a cool lever action rifle in .30-30 looks just like a Winchester model 94, weighs about 7 lbs, which is lighter than the shotgun by several pounds, it also seems magic. Next is a break open double barrel, over under rifle/shotgun, the top barrel is 12 gauge, the bottom is some variety of .30 caliber, this gun is nearly 12 lbs, and very long with a 28” barrel, and also seems to be magic. Last is a bolt action scout style carbine with a short 16” barrel, forward mounted 4x scope, and 10 round detachable box magazine, you would guess is some .30 cal as well, it is also about 7 lbs. it also seems magic.

You look them all over, “Very cool, but I think I like my 12 gauge.”

He says, “Ok, one more idea, what if I throw in a magic dagger.”

“Oh let me think, what about ammo, how much.”

“Sure, for the .45, I sell loaded in packs of 10 for 15 silver, if you bring me the brass I will load them for you for 1 silver each, or I can sell you the powder n bullet for you to reload, 5 copper each, well 10 for 5 silver that is. 12 gauge is the same for buckshot or birdshot and double that for slugs. My .30 cal rifles I sell ammo the same, basically, but a pack of 10 is 22 silver, for me to reload is 2 silver, and powder and bullet 10 for 8 silver. If we do any trade I'll throw in a bullet press so you can reload.”
