Hey John I found some shells along the coastal cliffs here that look very similar but I can't be sure from the pics if they're the same. I think the significant feature is the flange at the back end of the shell. The fact that it protrudes past the dia. of the casing, I believe, means it was manufactured to be used in a stripper clip. My ammo knowledge is a bit rusty but I believe they were .30 cal. rounds used in 5 round stripper clips to allow for fast reloading of certain .30 cal. military rifles. The original speedloader. I found a few of these rounds and a stripper clip in the same area awhile back. Cleaned em up and they snapped right in. Also, if my memory is correct, some mass produced WW ll military brass didn't have head stamps designating cal. etc. So my guess is .30 cal. WW ll ammo. My camera sucks but I'll try to post some photos for you to compare. I'll also talk to some friends I used to shoot and reload with to check my facts and get any additional info. Hope that was at least a little helpful.

Most likely they are rounds that went in lever actions, probably Win. 25-20 or 32-30's for example. I really doubt they're any 1900's U.S. military because they are rimmed (the rim is wider than the cartridge).

The length indicates a rifle casing and the width being just under 1/2 inch makes it approximately a .45 caliber. I would guess a 45-70 rifle round.

Don't know for sure but could be a 30 cal M-1 carbine round. Length is about right. I'm no expert. John

glad we got that cleared up.
