30 mi carbine problem or not


January 8, 2013, 05:00 PM
I am reloading 30 carbine & have to put a very hard taper crimp to keep the 110 gr bullet from moving back when I push it against the table edge.
Remington 110gr jacketed SN
This brass has been reloaded 7 or 8 times.
Do you think the brass is the problem ??

Either your sizing of it is a problem, or its lost critical tension/springback.

NEither is good..........

Although, the # pressure you are pushing it into isn't stated... " hard and very Hard" are subjective.

"Excessive" crimp is never the answer to a reloading problem. "Excessive" being outside what is published and customarily employed.

A definitive answer could be obtained by sizing a piece of new brass- and seeing if you encounter this problem.

If you do, 'taint the brass, my friend.

If nothing else in your setup has changed such as new dies or a new setup on the old ones you may need to anneal the brass. More crimp is seldom the answer to neck tension problems.
Hope you get some additional info.

I have spent qite a bit of time on the matter as well. I could not get enough bullet tension to keep the bullet from falling back into the case.

I tried two different sizing dies. One was an RCBS and the other I forget what make. With both dies, I still had the same problem. They both sized the cases to the proper spec.

What it all boiled down to the cases bing old and losing their tension strength. I was thinking of trying annealing next. It may help. We will see.

Old military brass
I tried new brass & it does not setback
This brass is good for one more light reloading.
I uas the cylinder from my Ruger pistol to make sure the cartridge is OK.

Wilson will not make a standard gage for 30 carbine.
I called them & they said they don't make one & don't plan to make one.
The Ruger cylinder works good

Thanks for the help

I just won't use brass that many times in any semi-auto rifle!

It's simply not saving any money if one lets go, or the bullet sets back and you blow up an irreplaceable old rifle.

Not to mention, my eyes ain't going to be that far behind it either!

New brass is a Lot cheaper then M1 Carbines, or glass eyes!

I use it in a Ruger pistol

My rifle is an Iver-Johnson----a gun that I do not trust & never will.
12 gr H110 is as high as I go for the rifle.
If it fits in the Ruger cylinder --it works good in the rifle

I have not used these in many years----Feindstein got me interested.

Well, I assumed you were shooting it in an M1 Carbine I guess.

Set-back is not a problem in a revolver, as long as the bullets don't fall out under recoil.

That Iver-Johnson is made up of m1 carbine parts fitted to an I-J frame which is an exact copy of Military M 1 carbine.

Also on the cartridges I found if I take all the bell ( was using a lee expander die)out of the cartridge neck area & seat the bullet very carefully--that there is NO setback of the bullet on the older cases.

On 'semi-topic': Starline told me they will begin making brass for the .30 Carbine some time this year. :)
