Dating cartridge by headstamp?

[abqfox]

We found what appears to be an old cartridge while detecting today. The headstamp says:
Peters
45 Colt

With all of the research I’ve done on this, I have yet to find any mention of this particular headstamp. Most I’ve seen either contain the stylized P for Peters (which mine does not have) or some combination of RP (Remington Peters) and UMC. Mine just says Peters 45 Colt. Thanks for any help.

1st - I noticed this was your very first post - so, Welcome Aboard abqfox! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).

2nd - A picture(s) is worth a zillion words! If you are having problems posting pictures - take a look at: How to post pictures with your story...

3rd - I searched Google and found HEMBRILLO - An Apache Battlefield of the Victorio War.

There are headstamps that can help with dating. For instance, Remington and UMC joined up in 1912, so headstamps with simply UMC on them will probably pre-date 1912. Cartridges with no headstamp are probably before the mid 1800's. Peters made a lot of ammo, so it's tough to pin down the age of your cartridge. Remington joined with Peters in mid 1930's, so the headstamps became R-P after that.
