This is?

[MikeS.]

I’m pretty sure this is 7.62-51 (.308) but can anyone confirm for me?
All my reloading stuff is packed away getting ready for our big move

 

[Inglis]

Yup,yup.

 

[MikeS.]

Yup,yup.

Thanks

Just an FYI, the circle with cross on the headstamp is the NATO symbol, so it could only be a caliber that NATO has adopted. So, technically, it is a 7.62x51. Same dimensions as .308, though.

Generally that's true, but there are exceptions. I once bought some .243 brass that was formed from 7.62x51mm LC brass. One could easily form a 7mm-08 case using 7.62x51mm brass too.

Got a caliper?

Very true!

I received some 300 Winchester from @Toprudder a few days ago. I am sizing along, and all the sudden STOP......? Someone had taken some 300 Winchester and necked it down to .284 I think. No worries, I muscled up and necked it back up to proper caliber, .308............... Loaded it today in fact.

You never know, I use 270 WSM to make 6.5 WSM. Sometimes 300 WSM, down to 270, then on to 6.5. I use 325 WSM to make 338 WSM, did 200 of those last week or two. Then I use 300 RUM to make EVERYTHING...........I have made 358 RUM, 9.3 RUM. 9.3 B&M, 375 B&M, 416 B&M, 458 B&M, 475 B&M, 50 B&M, 500 B&M, 458 B&M EX, 458 B&M SA and 50 B&M SA, all out of 300 RUM or any other RUM............... I have used 375 H&H and 416 Remington to make 458 Lott and 470 Capstick. I have used 375 H&H and 8mm Rem to make 358 STA.......... and I could go on and on and on............ Sometime Head Stamp don't match, but not a big deal either...... make it whatever you want..............

7.62X51 or 308 makes good 338/08, or now 338 Federal, or 358 Winchester.... a bunch of lesser calibers....... I even have a friend in Australia that took it to 416..............

Sort of like dating in today's society. Just because it looks like one thing 👠 you don't know till you check it out. Could be something completely different 👞.

Bottom line, it looks to be a standard Lake City 7.62x51 NATO casing circa 1987, unless it's been resized to something else.

Sorry about that!

It’s definitely .308. Neighbor has calipers and we checked them. I have a lot of them that I primed 5 years ago and put them away when we moved. Getting ready to move again and rediscovered them.

 

[Michael458]

Sorry about that!

Oh no, nothing to be sorry about...... I did not see it either until running it into the size die......... Even after, it was hard to pick out, was only about 20-25 of them........ Was of no consequence, run them on through size die and expanded the necks, loaded right up..........

Getting ready to move again and rediscovered them.

Like finding new stuff all over again, cheaper than shopping for them.................

It’s a great find. I’ve already sized and primed them. Although I have a bunch of primers stashed it still saves what I have of stashed primers for other projects.
