No signs using Hornady and Norma brass and Federal 210 primers.What do other brands of brass look like out of the same gun?
Case neck wall thickness .160... I think i would be inclined not to listen to that guy. For reference that is over 1/8". The listed variance is more than my Nosler 280 brass is thick.Interesting observations on Peterson Brass in this thread. I was using Nosler brass in my 280 Ackley and had a lot of inconsistent premature pressure issues. I really felt from my personal anecdotal experience that Nosler brass is crap.
Since switching to Peterson “all has been right with the world” to quote another poster. It seems night and day in quality to me.
Someone sure the hell likes Petersen brass because when it comes to getting to 280 Ackley Peterson brass, it’s like trying to find unicorn turds. I just snagged 100 pieces Grafs the other day, and that stuff was gone in a few hours.
This guy did a comparison between 280 AI Nolser and Peterson: https://schoutdoors.com/threads/high-quality-brass-experiment-280-ai-nosler-versus-peterson.15575/. “Clear winner is Peterson in almost every category.”
time for new equipment on the benchI think you should turn the necks for .005”+ clearance and your pressure signs will go away.

Also found a related thread, using Peterson, that sounded very similar
Neck Tension and Pressure Signs
I've been struggling in my 6.5-CM loads with pressure signs (heavy bolt, extractor swipe marks, etc.) in loads that absolutely should "not" be delivering them. I'm talking about velocities that are hundreds of fps slower (2400-ish) than factory ammo (2700-ish) ... that by the way ... shoots...www.snipershide.com
Yes, similar experiences, though im not having any stuck or sticky bolts.and that guy has a .296” fired necks. More clearance than you have and the same problem. Have you tried other brass?
Interesting…. I had not noticed that. Did he forget a zero or is he adding two walls together to make the full diameter difference?? I’m no mathematician. Good catch.Case neck wall thickness .160...

My Nosler 280 brass has been fine. It is sitting weighting for its 9th time around. Of course it hasn't been pushed to max pressures each firing either.
You think .080 thick would be good?Interesting…. I had not noticed that. Did he forget a zero or is he adding two walls together to make the full diameter difference?? I’m no mathematician. Good catch.
Probably. I’ll measure a virgin piece when I get a spare moment.You think .080 thick would be good?

It's looking likely.You have neck turning in your future.
The ejector does not look too long.@dmuffman80 Before and after pics of the bolt head. I clean off the grease prior to shooting.
It's looking likely.
Not sure if it's worth it at this point, but i lean toward staying safe than anything else. The (factory) barrel has 1300 rounds through it, and its about this time that i started seeing these signs. Fouling? A re-barrel should be sometimes this year.
Sidebar here, lol, when you have a problem, involving 10 strangers with 10 opinions a quick fix usually is not in the cards.@918v
0.2910 after FL resize and no bullet.
0.2925 with bullet seated
Bullet is a Hornady 140 ELD-M measuring 0.2635 average.
Measurements taken from a Mitutoyo CD6 ASX.

Pick one or 2 of these guys, and follow their lead, exasperate their ideas first.
918 and spife are pretty solid, more are too, I am just more familiar with them>
I respect your advice, and rocketman, fucking elton john in my head, lol, and supercorndoggie's.In another thread recently, a member stated that neck clearance doesn't matter. Not all advice is good advice for sure.
What are the pro (cons are clear so far) for manufacturer creating tight necks? Do you still find yourself neck turning since changing neck dimensions?When you rebarrel ask for a standard size neck. My brass expands to .296” and I don’t have any pressure issues. The last time I had a tight neck cut I saw what you’re seeing- low velocity and pressure signs.
I think you are pointing a finger at the wrong manufacturing process. In a factory rifle, tight neck may be that chamber was one of the final ones done by that reamer, it may be worn.What are the pro (cons are clear so far) for manufacturer creating tight necks? Do you still find yourself neck turning since changing neck dimensions?
This has been a great thread. Thank you all for sharing your knowledge on this. I'll be looking into the different neck turners on the market. I'll have to debate whether to change out the current barrel ~1k rounds early (with the proper neck size), or get turner on the bench.

I've found Peterson brass to be excellent in my straight 284
