Bullets shouldn't be magnetic since they are made of brass, copper and lead, but I guess these ones had enough rusty ferrous material stuck to them that I pulled them out with a magnet anyway.
The little rod below the horseshoe is also entirely made of copper and not all magnetic, but it was held on to the magnet by some rusty scrap.
I also got a fair amount of loose change, and what I think is a door knob that I was a little worried could be a grenade when I pulled it out amongst the bullets.
Yeah I think it's a cool find too. Some of those look like .45 ACP, so it would be neat to display them alongside your 1911. The caliber should be written along the outer rim of the bottom of the shells, just outside the primer cap. I originally missed that you're in the UK. I wonder if any of those are WWII relics!
Yeah I guessed that was what they were, I'll have to check what they say on them and confirm it. I think one might be a .22 LR or HMR but I'm only basing that on the fact it's small and long!
I'm definitely going to work out a way to display the better condition ones next to the 1911. There's a good chance they are from WW2, most of the guns used in crime here are old ones I think, so it would make sense that the ammunition is too.
That long skinny one is too big for a .22 LR. Idk what it is, but I don't think it's a .22. .22's are really tiny.
