Anyone know if this is true.

There are three 7.62 rounds. 7.62x.51 and 7.62x.39 and 7.62x.54

7.62x.51 is a .308 winchester, 7.62x.54 is a thirty odd six

Yes but a 7.62 x 51 is not exactly the same as a .308 from some of the gun forums I've been on. I've heard that damage could be done to your rifle using the surplus 7.62.x 51 rounds in a .308 rifle. Is this in fact true or is it safe to use them?

I've never seen surplus 7.62 x 51. I've seen lots of 7.62 x 39, which is what the AK shoots.

Although the dimensions of the 7.62 x 51 NATO round are virtually identical to the .308 Winchester round, the 7.62 x 51 are loaded to a higher SAMMI spec ( chamber pressure )

What kind of firearm are you thinking of shooting the 7.62 x 51 round in? What kind of shape is it in?

The issue is neither external brass dimensions (which are identical)
nor pressure specs (SAMMI specs for the .308 are 62K CUP,
for the Nato 7.62 are 58K). The issues are twofold: the
greater thickness of military brass vs commercial (military
is thicker, allowing for much case flowing of shot cases),
and the headspace allowance of the NATO chambers vs the .013"shorter headspace allowance for the .308.

Shooting fresh (unreloaded) 7.62 ammo in a sporter .308 will cause no
ill effects; trying to chamber reloaded military brass that has not
been full-resized (not just neck sized) will cause headspace problems, blown cases and all manner of bad things.

The guys that reload 7.62 brass without full-length resizing for .308
are the ones who have issues. Regular sizing dies for the .308 are neck-sizing only, you have to buy a special full-length carbide resizing die to get full length resizing on the 7.62.

I recently watched a fellow trying to close the action of a very new, very nice and expensive customized FN TSR XP on some reloaded 7.62 ammo (baggie brand); he was using a wooden mallet to hammer the bolt closed. After firing the one round the action seized and even with the intrepid fellow slamming the bolt handle on the side of the table he was unable to get it open again.

We breathed a collective sigh of relief when he packed up and left.

Nice.

This is what I am talking about...get your hands on what is available. .22 LRM or 9mm, or 5.56 .223 Rem

Ka-threadbump...

My XD45. It stays under my pillow. It helps me sleep.





My Keltec PF9. It comes with me everywhere I go, except work and school for legal reasons. It keeps me social.




Sometime in the next month or two I'm going to be shopping for a replacement for the Keltec, preferably something in a .45 caliber.

Nice. Erik just sold his (my) XD45 because he didn't like that caliber. I did but it wasn't mine to keep.
