View Full Version : 7.62 NATO trimmed too short

I came into a bunch of 7.62x51 LC brass that was trimmed too short. In a cartridge OAL gauge, it's a few thousandths too short after having been deprimed & resized.

What can be done with this stuff, short of necking it down to .243? Can it be loaded for blasting ammo, like cheap fodder for an FAL? I'm guessing on subsequent reloadings the brass may flow enough to make it good in overall length, assuming it can be shot in the first place.

Don't worry about a few thou. under. They could be .010 under and not matter, the case will grow when you fire them.

Agreed. I used to get all bent out of shape when I trimmed a few a little short. Don't lose any sleep over it.

I would agree also just use it as is

Have you measured to determine whether the shoulder has been set back too far?

If the base-to-shoulder dimension is OK, then the brass is probably OK.

You won't be able to tell base-to-shoulder dimension is OK unless you have one of these.

I got one of those Dillon case length thingys many winters ago. (.30-06) Haven't used it a a few moons. Doesn't it not only tell you if the OAL of the case is in limit, but when you put a case innit, if the head is within range, ya know that too ? Simple, no moving parts and cheap. (well, as cheap as compared to many things Mr. Dillon insists we can't live without)

Maybeso I be fulla stinko again. :(

Gary,

I have that same RCBS gage and when I measure my headspace gages (go, no-go, and field) they all measure .002" shorter than indicated on the headspace gage.

I have not attempted to measure the headspace gages on a shadowgraph but based on the .002" being constant, I'm wagering that the RCBS gage is wrong.

Hey Pete, I'll give you the old saw. It's dangerous to shoot. Do not, I repeat, do not reload. Bring them back with you and I'll dispose of them properly.
Have fun in Fla.

HA! They're actually sitting in the garage, unused at the moment.

I'll have to check the shoulder when I get back, I'm not sure if that was what was set back, or just a short trim.
