Bullet found, What type? I am unsure.

[Retired Fire]

Any Idea? Modern or not?

I dug this at a depth of 8 inches. At first I thought maybe a 45 cal. but it is longer and narrower than a .45 ACP or .45 Colt.
In the first photo it is next to the .45 Auto and .45 Colt. I think it is modern but just not sure. Could it possibly ne a Martini Henry round?

It's a modern bullet with the ridges in the cannelure.
Possible modern 45-70

2x on the 45-70

3x on the 45.70. I used to shoot hand cast bullets in my 1886 Winchester, and I think they weighed 360 grains. Military loaded a lot of 405 grain bullets. That cartridge was used by the military for years, and in fact some national guard units were still using the Springfield trap door 45-70 up to WWI. Off hand I don't know the weight of the bullets in factory loads, but with the reeded grooves, yours is a factory load from probably around 1900 or even more modern than that. I still shoot 45-70's.

Wow, great info. Thanks for all the help! SOLVED!

I dislike stirring up the pond when the ID has been agreed to. When I first saw the photo of the bullet I thought it was a late-1800s/early-1900s version of .45-70 rifle bullet. But the finder says it is "narrower than a .45 ACP or .45 Colt." And, in the photo next to those .45 bullets, it does look smaller in diameter. If that's not an optical illusion, it might be a .40-60 Marlin Model-1881 Rifle bullet, or a .40-65 Winchester Model-1886 Rifle bullet. We need the finder to borrow a Digital Caliper and give us a precise measurement to confirm his statement that his bullet is "narrower than a .45"... and thus is not a .45-70 bullet.

TheCannonballguy, I will stick a caliper on it at work tomorrow and get some precise measurements. Thanks for the input. I will get back to you, Thanks

Naturally it is slightly out of round. But here are the measurements in mm. Sorry but apparently the button for inches is not working.

10.42 mm converts to .41 caliber

.405 Winchester?

I refuse to answer metric measurements in the US. ;-)
