Okay I need a little help.

A guy I work with bought a beauty of an M1 Garande several months ago, then went on the hunt for some bulk ammo to shoot and finally gets a deal on 400 rounds of 30.06. Well, he gets his order and well the bullets are just a tad too long! They wont chamber properly.

The casing even looks slightly different and has the markings of H X P 77. My google fu says they are a Greek variant with some mixed reviews.

Any idea what this is and what it is for? He wants to send it back but I guess the place he ordered from says it is 30.06 and all sales are final.

And of course since I was SF I must know about every bullet and variation ever made so he came to me! I told 'em I was freaking Charlie and my Bravos didn't want me to handle any guns! HAHAHA

Greek ammo shot great when I had my Garand. Very accurate. Have him get his chamber checked with a go/no go gauge or at least try to slip a factory unfired case into the chamber. The Navy re-chambered a lot of Garands in 308 and used them until very recently so it is posable that might be the problem.

If he has a tight chamber within specs he can always get a bullet puller, bump back and resize the cases then reload them with the same powder and bulletts. Just remember to weight how much powder comes out of several rounds then average them.

Yeah we talked about that but a 308 round is much smaller than the 30.06.

First round in the below pick is the HPX 77, next is a 30-06, next some of my .308 rounds (180 gr and 150 gr)

He might just have a tight match chamber. How far does the ammo go in? Has he tried any other ammo? Can you describe what it is doing? Was it re barreled by a civilian? They have marks on the bbl and the date it was barreled.

You can have a go gauge put in

Try different ammo. Hornady makes ammo for the Garand specifically

have the chamber cast to make sure it is OK.

Have you measured the ammo with calipers?

You are correct, it is Greek 77 headstamped .30-'06 ammo.

I'll take it and expend the bullets for him, if he wants. :D

The Greek ammo I've used is as MILSPEC as any other. CMP sells pallets of it. If the Garand was rebarrelled with a short chamber and not properly headspaced with a finish reamer that might explain the problem. Have him take it to a (competent) gunsmith with go/no go gauges and get it checked. (Your comment about "a beauty of a Garand" is an indicator that it has probably been refinished.) Aftermarket barrels are usually 10thousandths short so they can be headspaced by the gunsmith. I wouldn't recommend he shoot it until it's been checked. Attached is a photo of some .30 carbine brass I found at my local range. I thought I'd discovered a bonanza of once fired brass until I looked at it. After discussion with my gunsmith, he verified my assumption about it having been fired in a weapon with bad headspace. Hopefully the knucklehead didn't damage the carbine in the process. I would emphatically recommend against trying something similar with a 30-06.

TRBeat me to it; guess I'll have to continue with my own ample stash of HXP, also bought en masse from CMP.
Dx: un-finished chamber likely.
That chamber in proper dimensions (it's ogive, not an overall length issue) should have no issue with HXP ball, nor even the old 163gr long-ish AP which was its standard wartime meal. Mine eats both with gusto.
