30-06 cases tight in chamber

[Jim P.]

I ground .002 off the end of the die. we will see how it sizes when I get home tonight. I just clamped it in a precision v block and placed the v block on its side on the surface grinder

[Jim P.]

here is picture of the die after I ground it off

Many of us who shot M1's and later 14's got our hands on lots of TW/LC 06 and 7.62 brass that was fired in full autos. Always used the SB sizer before 1st reload . They might've run in issue barrels but most HP shooters had rebarrelled with tighter chambers.
Whatever works !

Let us know how it works out .

I sized them the first time with a shim under the head of the shell to where they were actually a few thousandths short. I then shot them but when I resized them the second time without the shim they were again tight in the chamber

Swollen base could cause the length to grow when resizing if your die is on the long side + spring back . How are they sizing now with the short die ?

[Jim P.]

They are sizing great now. Bolt just closes now without having to man handle it.

Ain't it wonderful to have the right tools for the job!!!

[toallmy]

Right on

Glad you got it resolved.

I think you have it working now but let me know if you still want to try the go gauge. I'll have to dig in the shop. I'm trying to start cleaning up after a five maybe six year break due to health and man it is a mess.

I appreciate the offer but it's working fine now. It the gun does have a tight head space, it doesnt bother me. If it ever wears a little it will be right on spec. lol

Here is a little bit of information about 30-06 that I did not know. maybe this is why the military cases are hard to size.

There are many good sources for military ’06 brass on the market, but be careful when using them; the military stuff has a thicker case wall, and therefore a smaller combustion chamber, and it will reach higher pressure with less powder when compared to the commercial cases.

[Jim P.]

I did notice when I was loading , I had one norma case. It was not as full as the military cases with the same amount of powder. I actually dumped it out reweighed since I thought I made a mistake but did not.

[uscra112]

SOME military -06 is heavier, some is not. I did an extensive evaluation of 5.56 brass about 6 years ago, and followed up with a couple hundred each of 308, and .30-06 . The stuff to really watch out for, from my weighing and measuring marathon, is the foreign makes. Your warning is well taken - don't assume anything if it's military. Weigh a few samples, and do the water test.

Sorry late to the party - I see it was for a savage - You could have just loosened the bbl nut and turned your barrel out .000"s
Probably set tight from the factory.
I have all my Savage's set tight but they are dedicated dog guns.

I dont have a wrench for the barrel nut. It also would chamber factory ammo fine

[Bazoo]

If it were me, I'd grind the bottom of the die so it replicated the shoulder length of factory ammo. That way it would be sure functioning through my gun. Course you can always set the die to size less to extend brass life, but having a bit of space for dirt may be beneficial some day.

[uscra112]

Which is what he's done.

[Bazoo]

I don't think he mentioned what difference between a fired case and factory there was. Or least I missed it if it was mentioned.
