Default What kind of bullet is this?

All but the tip was encased in asphalt-like rock. My daughter found it in ocean and thought it looked like an ice cream cone. She tried to eat the rock part (yeah, she's super advanced for her age). It's been rough and windy last couple weeks, all sorts of cool stuff has been washing up on the beach.

Tapped the rock away with a cold chisel and this is what I found. It's one piece, doesn't appear to have any seams like a modern bullet, but the ridges suggest it's not that old either.

My wife (also super advanced for her age) is convinced it's solid gold.

Any ideas what I might have found?

Standard size iPhone 6s for scale. Don't have a tape measure handy.

I'd estimate 3/8" widest part, 1.75" long.

What's a boat tail?

Tapered rear end, generally for longer range and better stability

50 cal maybe? boattail, modern bullet, the groove with the texture is where the case mouth is rolled inward to lock the bullet in place, the second groove is to lower friction, it's an unfired bullet, no rifling grooves

Good call, except unless that dude has massive fingers I'm leaning toward .30 cal

So it's not solid gold and it's not an antique?

Shit.

Here's a 20mm sitting on my wife's galaxy S4 for reference.

Hard telling exactly what, but definitely not .50. Could be .338, but can only tell for sure with exact width!

Put some mic's to the dia and calipers to the length and weigh it. Should get you ballpark. Take it by a gun shop that also offers gunsmith service so they have people there with tools. Funny post.

Silly, everyone knows you have to use a banana for scale.

That's sure looks like it.

As long as its not a priceless artifact I really don't care what it is. I knew I'd get a definitive answer on here and you guys didn't disappoint.

My guess was .338LM but looks like it's a .50 or similar. Photo is a 300g so that bullett is pushing double the mass.

it's 2017, as evidenced by this thread, everybody knows a cell phone is the universal scale reference.

There are a couple "ammo dumps" five to ten miles offshore, right off the beach from me. Chances are it washed in from there.

They're marked on all the offshore maps for CHS area. I never realized they were actually Ammo dump zones.

My first thought was .50, but he said 3/8" wide. Don't need a micrometer to tell us if it's 1/2" across!

It's a .50cal. Typical of US military or USCG vessels equipped w/ Browning M2 HB machine guns. Much larger than a .30. It's as simple as measuring the diameter. You'll find that the bullet is .50 inches.

Looking at it on the phone, I would also call it a .50 cal.
