I have no clue about old bullets. I've found a few of these and have always wondered what they were. And what's with the flat end? I like the ones with the four rings around them but I can't seem to find any info, age etc. Any help would be appreciated.
We have to have measurements to know for sure, but I can tell you that the flat nose on the bullet was because they were expected to be loaded in a tubular magazine, ie: one behind the other, and it's not wise to have pointed bullets sitting on the primer of the bullet in front of it. They probably date to the late 1800's early 1900's.
Here's a picture explaining about a tubular magazine, you can see how the bullets are lined up, and sharp points resting on the primer in front, the force of the recoil might cause the cartridge to fire. It has happened.
Thanks for the info....the flat end makes sense to me now. The ones with the four rings measure .380 and the other ones measure .420.....if that helps. We are a long, long way from the Civil War battlefields, just figured they might be pretty old.
