What gun does this ammo go to?

The first one definitely looks like pistol round and could very well be a .45 ACP. You can see the number 42 on the base, but To the best of my knowledge, there's never been a .42 caliber handgun. Most likely, the number 42 refers to a lot number or a manufacturer number. It's hard to tell in the photo, but the second one looks thinner and longer. I would assume it's a rifle cartridge, but it's hard to say with no measurements. Reminds me of the old .22 long rifle, but those were rim fire cartridges. I think I've read about a small center fire she'll, but I can't remember anything about it.

They're definitely not 30-06 shells.

 

Where would one go to sell or even donate it? I'm never gonna shoot it

 

Yea you've just got yourself some old .45 auto. I wouldn't shoot it though. It's kinda cool to hang on to. Not to mention it doesn't want to chamber so that's not the safest thing lol

 

Good call on the .30 cal M-1 carbine ammo.

 

Assuming that 42 is the year of manufacture, definitely not a rowland. That's a pretty new round. Looking at the pic the brass looks to be pretty equal in length, rowland brass is a smidge longer to keep it from loading into non converted 45's. I've got a bunch of 460 and 45, you can sort them by sight alone.

Really without them in my hand... it looks like a 45 acp. Nothing visual says it shouldn't chamber. Good chance your chamber either doesn't like it or it's not a perfectly sized reload.

 

OP, the pistol round's headstamp's a little blurry - is it "WCC 42?"

If so, it's Winchester manufactured ammo.

 

No that's very common American ammo.

 

WCC 42 is military made by Winchester in 1942 the LC 42 is Lake city arsenal also 1942 All of the ammo shown is very corrosive and I wouldn't even dream in shooting it

 

The .455 Webley & Scott Auto is a semi-rimmed cartridge initially intended for the Webley & Scott Self Loading Pistol Mark I. The cartridge first appeared in 1904 with a 0.885 ins case and very thin rim. A second version, thought to be from around 1910, has the same thin rim but the case is about .927 ins long. This was the later production case length. The official production round, the Mark I was approved in 1913 and was produced up to the middle of World War Two. It had what we would consider a normal rim thickness. All versions were semi-rimmed and, except for the 1904 version, all had the typical jacketed blunt projectile.
