Default Creedmore ,30 cal carbine

I purchased 250 rounds of this ammo from CMP.
It will NOT feed in my S.S.G. rifle. I do have several other brands of ammo as well as home loads that all feed without problems. The OAL length of this ammo is within specs, but is .030" longer than any other ammo I have. I may try seating some of this ammo a bit deeper to see if it will feed.
Anyone else have issues with the creedmore .30 cal carbine?

What is the OAL? Seating the bullets deeper may raise pressures.

More detail, The Aguila ammo (sold thru CMP several years ago) measures from 1.631 to 1.636, my Hornady handloads measure from 1.627 to 1.630, My frontier bullets handloads measure from 1.627 to 1.631 All of these function perfectly. The Creedmore ammo measures from 1.658 to 1.661 and will not feed. My Hornady, 8th edition load guide says max C.O.L is 1.680
My plan is to seat these deeper .005 at a time untill they feed properly or show signs of over pressure. If I get down to the 1.630 size and they still do not feed, I will eventually shoot them up one round at a time as a single shot firearm. I will not buy anymore of this ammo.

At the last CMP games I attended in Vermont the shooter next to me at the carbine match had the same feeding problems using Creedmore .30 carbine ammo. The blunt nose of the bullet kept jamming on the feed ramp. I believe you may be right about seating the bullets deeper. Good luck, Eddie

The overall length (OAL) dimension is only useful if you're using a bullet of the exact same ogive and shape.

I load .30 Carbine using several brands of 110 gr. RNFMJ, RNSP and 100 gr. Hornady SJ. I load all my cartridges to 1.680" OAL. These loads function fine in my 15 carbines.

You are talking about "CREEDMOOR" brand ammunition, correct?

The "Creedmore" brand is the ammo that does not feed. I have reseated the bullets farther into the case (COL is now 1.635) and they still do not feed.
I will eventually use these up by loading one round at a time into the chamber and closing the bolt.
