Anyone doing it? Are you neck turning? I have a little bit of a doughnut at the top of the shoulder, but it seems to chamber fine(it's a semi), extracts easily. I have a box of Lapua .308, 7mm08 brass is expensive for good stuff so it would be good if I can use it.
I don't neck turn and CBF doing it.

Once fired it will be fine and the ring should be gone.

I've been using it for a few years now. I didn't need to neck turn and haven't had any issues using the brass whatsoever.
what He said ^^^^^^
if the doughnut causes trouble with bullet seating you can always get a case neck reamer and ream the inside of the neck to get the bullets seating without any issue.
For a ar?Quote:

Oh ok I didn't realise it was for an AR so please forgive my ignorance.Quote:

So its more a false shoulder than a donut, if it chambers well then it shouldn't be a problem . Iv seen 2 rifles that needed neck turning after necking lapua down to 708. Measure the outside of a fired case from your rifle and a loaded round using your necked down brass. You will need to have some clearance to be sure of consistant functioning. .002 at least for a bolt gun, most of mine are around the 3-4 thou mark.
Roger that. Usually if you have an oversized case in an AR it either won't feed or if it does it locks the action up hard, haven't had that so fingers crossed.
I wish Lapua made 7/08 brass
Just use Winchester :)Quote:

Depends on how hard you want to push the brass? Lapua make harder cases than Norma but i believe the Norma brass is more consistent.

Both 41 and 40.5 grain loads produced groups well under .5" center to center. I'll definitely have to load some more up and see if it wasn't a fluke. It is quite a punchy load, I can feel it in the action when it cycles. There is a little case head swipe on the brass and the primers are starting to crater a little, don't really want to push it far past that. 2209 might be a good option for more speed but I don't really want to try it until I put my adjustable block on - port pressure will probably be very high. Regardless I am pretty pleased with how it's shooting, and a 154gr SST at 2600fps gives me quite a useful load to play with, decent trajectory and retained speed/energy.
