I reloaded some new Remington .308 Rifle Brass FLS the cases and loaded three seperate loads using imr 3031. Load 1 WLR primers, ogive to head length 2.125, 37.5 gr. imr 3031 using Sierra 150gr GK spitzer. This load was somewhat under pressure. Next load was WLR primers ogive to case head was 2.175 imr 3031 39.1 gr. this was the best load under half inch from tikka t 3 lite at 100 yrds. Last load was WLR primers imr 3031 ogive to case head 2.150 imr 3031 42.2 gr. This was not a max load but its the one next to it. Firing these loads caused a noticible pressure ring above the web. Is this normal for Remington Brass or do they just happen to make lighter brass than winchester. Also this load shot a half inch group at 100 yrds. I have some Winchester Brass that has never done this on the first firing.

Just checking a Nosler manual with their 150 -155 gr bullets they list IMR3031 MAX laod as 45 grs and the starter at 41 grs they also list the 41 grain load as the most accurate.
Lyman lists 40 as a start and 43.5 as MAX with 150 gr spitzer.
Do you see any other signs of over pressure? If you were shooting a bolt gun was the bolt lift unusually hard?
You could do a water volume test on the brass and compare it to the Winchester to see if it is thicker thus less volume and high pressure with the same loading.
From your statement on overall length it doesn't seem you are forcing the bullet into the lands and causing higher pressure that way.
I haven't shot Rem brass in .308 but have in several .224 cal loadings and have not noticed the ring you have mentioned.

I am not loading off the lands i was just testing loads. The Sierre SBT is kind of short to try that i was looking for accuracy. There was no other signs of over pressure on the case except the pressure ring. Primer isn't flattened and no cratering of the primer. Also the high pressure load i am talking about was under half inch at 100 yrds. As far as im concerned the cases with the pressure ring will go into the trash. I will stay with the 40.7 gr. load since it was very accurate. I had no problem at all with ejecting the shell caseing it ejected just like smooth as silk.

That ring is not a "pressure ring" so much as it is a stretch ring.
When a rifle case stretches, that is where it does it, and a shiny ring is formed.
Perhaps a headspace problem from FL sizing them too much?
New brass is soft and has little spring-back when the shoulder is pushed back by FL sizing.
You might back of the sizing die & just neck size them until you fire form them by shooting them the first time, and then they won't stretch so much on the first firing.

Remington Brass Primer Pockets
Remington and Lapua are the very best brass for retaining tight primer pockets through many reloadings. I tire of throwing away good-looking brass with loose primer pockets. Worst offenders to best retainers: Nosler brass, Winchester brass, Hornady brass, Remington brass, Lapua brass. I've tried nothing else, but I only buy Remington and Lapua brass now. Just my experience and opinion. cliffy

Giz,
Run a wire with a small hook on the end, down in the case and see if you can feel the "ring" on the inside. If so , it is a separation starting. The info of neck sizing should stop the stretching, if head space is the problem.

I cannot feel the ring with a wire with a hook on it. Should i try to FLS these few cases again or just neck size. I think i know one problem is i am using Hornady lock rings on the dies and when set they don't give at all like the rings on the Lee dies with the o'ring on the die.
