unknown cartridge

[trout69]

Hello:

It has an "A" and a "5" opposite each other. You cannot see in this shot due to the angle but there is what appears to be a "C5" or "05" on the right hand side of the cartridge in similar lettering to the "A" and "5".

Less certain.. there is small writing near the "A" which appears to say "ASI"?

Online research suggests early 1900's but I cannot find this cartridge.

Thanks

Forgot to place the dimensions. I placed it on a caliper and it was either .44 or .45 inches in diameter.

Re: unknown rifle cartridge

A profile photo along side a ruler would sure help.

Forgot to put that... it was .44 or .45 inches in diameter. I do not know the length because it was rusted off.

I can't be 100%-certain about this, because (as you mentioned) not all of the headstamp-markings are visible in your photo of the markings. But from your in-real-life observation's description, it is a (US) Frankford Arsenal cartridge manufactured in the 5th month (May) 1905. In that era at the Frankford Arsenal, the orientation of the markings on the cartridge's base were an F at 9-o'clock, an A at 12-o'clock, double-digit year of manufacture at 3-o'clock, and month of manufacture at 6-o'clock.

Being Rimless, it's not any of the second photo.

Try Rubbing the markings with chalk and see if you can see them better.

Is it a steel case? Looks like a WWI or II steel case rifle, but just guessing since the nose is missing. Monty

Thanks for the responses. I am leaning towards the Frankford Arsenal round. I used dilute vinegar and then chalked right before the photo. Good advice. Thanks. I have posted the last photo which I believe shows the "F" and the "A" at the top. The "5" is at the bottom. You will have to trust me on the "05" because it does not show well on the photo.
The cartridge is not magnetic. Not steel.

Thanks again for the advice and your time. I learned a lot.

Thanks for the advice. I took another photo.

You did good. I posted the last photo at the bottom that I believe confirms your theory. I learned a lot.
Thanks again!!!
